How to test the Key Switch
1. Park vehicle on a level surface, turn key switch to OFF, engage the parking brake and remove key from the key switch.
2. Make sure that vehicle battery charger IS NOT connected to electrical outlet. Open the battery circuit by disconnecting the conductors between the battery pack and vehicle components.
3. Raise hood to allow access to wire harness connections for switches mounted in dash.
4. Label and disconnect wire harness connectors from the key switch.
5. With the use of a multimeter (ohms setting), the key switch functions may be tested to determine whether continuity exists between the B1 and 3 terminals for each switch position. The key switch terminals are marked as shown in picture.
A. When the key switch is in the OFF position, no continuity (infinite ohms) should exist between switch terminals B1 and 3.
B. In the ON position, continuity (zero ohms) should exist between switch terminals B1 and 3.
6. Replace key switch if testing determines that the switch is faulty.
7. If key switch tests correctly and circuit problem still exists, check wire harness for possible problems.
8. After key switch testing is complete, connect wire harness connectors to the switch.
9. Connect the conductors between the battery pack and vehicle components
Fuses Block
The fuse block is located under the seat assembly. All fuse block fuses are rated at 80
VDC.
1. Fuse block
2. Passenger hand hold
The fuse location in the fuse block is shown in picture.

1. 10 Amp (front fuse)
2. 15 Amp (bed lift kit)
3. 30 Amp (horn kit)
4. Optional kit
The front 10 amp (80 VDC) fuse protects the power supply to the key switch and all switched circuits. The battery charge indicator is also protected by the front fuse.
The second fuse position is used to protect the optional cargo bed lift circuit. When equipped with the bed lift kit, a 15 amp fuse (80 VDC) will be in the fuse block. The third fuse position is used to protect the optional horn circuit. When equipped with the horn kit, a 30 amp (80 VDC) fuse will be in the fuse block. The fourth fuse position is used for other optional kits, if equipped. An additional fuse is attached to the controller.
1. Controller
2. Fuse (425 A)
3. Screw (2 used)
4. Lock washer (2 used)
5. Flat washer (2 used)
This fuse is rated at 425 amperes continuous and protects the 48VDC vehicle power supply circuit. If this fuse has failed, vehicle operation will not occur.
Traction Motor Stator Winding Testing
Use a multimeter to measure resistance (ohms) between motor terminals (U, V and W). There should be very low (not zero) resistance between pairs of terminals (U and V, V and W and U and W). Also, measure resistance between each terminal and the motor drive end bracket. There should be infinite resistance between each terminal and the drive end bracket.
If resistance between terminals is either very high or zero, the stator is damaged. The stator is also faulty if resistance between any terminal and the drive end bracket is not infinite. If stator is damaged, replacement of the traction motor is necessary.
1. Thermistor connector
2. Terminal U
3. Terminal V
4. Terminal W
5. Drive end bracket
6. Encoder
7. Armature tone ring
Thermistor (Thermally Sensitive Resistor) Testing
Use a multimeter to measure resistance (ohms) between the pins in the thermistor connector. The measured resistance at 77F (25 Degree C) (motor temperature)
should be approximately 600 ohms. If resistance testing determines a short circuit (low resistance) or an open circuit (infinite resistance), the thermistor or thermistor wiring is damaged and the motor must be replaced. The thermistor is an integral component of the traction motor stator.
Encoder (Speed Sensor) Testing
If encoder problems exist, the vehicle controller should determine that a problem exists and a fault code should be displayed on the controller LED and the status indicator light.
Controller
The controller is secured to the rear frame beneath the cargo box. The controller uses inputs from several vehicle components to accurately control vehicle speed, direction (forward and reverse) and regenerative braking. Controller inputs include key switch, direction selector switch (forward/reverse), accelerator pedal, supervision speed limit switch, traction motor thermistor (temperature), traction motor encoder (speed sensor) and battery charger lockout. A single wire harness connection and five (5) cables are used to connect the controller to the vehicle electrical system.
1. Controller
2. Controller LED
3. Wire harness connector
A fuse that is rated at 425 amperes continuous is attached to the controller and protects the 48VDC vehicle power supply circuit. If this fuse has failed, vehicle operation will not occur. Cable connections for the controller are as follows:
Terminal B-: Negative (-) battery cable from the left, rear battery
Terminal B+: Positive (+) cable from the main contactor post
Terminal M1:Cable to traction motor terminal W
Terminal M2:Cable to traction motor terminal V
Terminal M3:Cable to traction motor terminal U
1. Controller
2. Controller LED
3. B+ terminal (+ cable from main contactor)
4. B- terminal (- cable from left, rear battery)
5. Fuse (425 A)
6. M1 terminal (cable to motor terminal W)
7. M2 terminal (cable to motor terminal V)
8. M3 terminal (cable to motor terminal U)
Because of the solid state circuitry built into the controller, there is no method to test it directly (e.g. using a multimeter). A LED exists on the controller to identify normal operation or faults that will prevent the vehicle from operating correctly. The status indicator light on the dash panel should display the same information as the LED on the controller. See chart below for light pattern fault codes identified by the controller LED and status indicator light.
NOTE: If the controller LED and status indicator light are flashing, attempt to reset the controller by turning the key switch to OFF, waiting several seconds and then turning the switch to ON. If the controller LED and status indicator light continue flashing after the reset attempt, proceed with fault code identification and necessary action.

Nintendo 3DS – Disassembling procedure – How to remove the mother board

Unscrew the four Phillips #00 screws along the top of the back cover.
The screws are held in place by locking washers, and will not come out of the back cover.
The comments section is full of unlucky souls who will tell you that the screws here through step 4 will strip incredibly easily. Press down fairly hard, and go slow.
Hold the device in one hand and turn it over.
Grab the top edge of the back cover with your opposite hand so that the cover does not fall back into place.
Flip the 3DS over again so that the back cover is facing up.
Pull the back cover up and away from the rest of the device to remove it.
Insert a plastic opening tool into the notch in the lower case above the battery.
Pry the battery up with the plastic opening tool.
Grab the top edge of the battery and lift it out of the lower case.
Remove the nine 6.3 mm black
Phillips screws from the lower case.
Remove the 2.4 mm silver Phillips screw above the game cartridge slot.
Lift the bottom edge of the lower case off the rest of the 3DS.
There are still two ribbon cables connecting the mother board to the case, so be sure not to pull the lower case all the way off.
Use a plastic opening tool to pry the shoulder button ribbon cables off their sockets on the motherboard.
Remove the lower case from the device.
Remove the two 7.7 mm Phillips screws securing the back of the
Circle Pad to the motherboard.
Use the flat end of a spudger to pry the back of the Circle Pad off the motherboard.
Lift the Circle Pad joystick off the motherboard and lay it on its back so that the ribbon cable connector is accessible.
Use the flat end of a spudger or your fingernail to flip up the retaining flap on the Circle Pad ribbon cable ZIF socket.
Be sure you are prying up on the hinged retaining flap, not the socket itself.
Lift the Circle Pad joystick off the motherboard.
To decrease the chance of losing it during repairs, you may want to remove the two thin pads underneath the Circle Pad joystick.
Use a spudger or screwdriver to lift the pads up and remove them from the device.
Remove the two 4.5 mm Phillips screws securing the SD board to the motherboard.
Use the flat end of a spudger to pry the SD board ribbon cable connector off its socket on the motherboard.
Insert the flat end of a spudger between the SD board and the motherboard.
Run the spudger along the sides of the SD board to free it from the adhesive pad holding it in place.
Once completely freed, lift the SD board straight off the motherboard.
Slide the flat end of a spudger under the corner of the Wi-Fi board, and lift it away from the motherboard.
The Wi-Fi antenna cable is still connected to the Wi-Fi board, so you cannot completely remove the Wi-Fi board yet.
Lift the Wi-Fi board off the motherboard and rotate it so that the bottom side is facing up.
Use the flat end of a spudger to pry the Wi-Fi antenna cable connector off its socket on the Wi-Fi board.
Remove the Wi-Fi board from the device.
Grasp the microphone ribbon cable near the microphone with a pair of tweezers.
Pull the microphone straight up out of the upper case.
Use the flat end of a spudger or your fingernail to flip up the retaining flap on the speaker assembly ribbon cable ZIF socket.
Be sure you are prying up on the hinged retaining flap, NOT the socket itself. Damaging the socket or cable will result in a 3DS that will blink its power LED when you press the power button - and do nothing else.
Disconnect the speaker assembly ribbon cable with a pair of tweezers.
Use the flat end of a spudger or your fingernail to flip up the retaining flap on the camera ribbon cable ZIF socket.
Be sure you are prying up on the hinged retaining flap, not the socket itself.
When reassembling, note that the gold contacts face toward the motherboard (as opposed to the camera cable's gold contacts facing away).
Remove seven Phillips screws securing the motherboard to the upper case:
Four 2.5 mm gold screws
Two 3.5 mm black screws
One 2.5 mm silver screw
Lift the side of the motherboard that sits along the bottom edge of the 3DS.
Continue lifting the motherboard assembly and rotate it until it is resting next to the rest of the device.
Use the flat end of a spudger or your fingernail to flip up the retaining flap on the LCD ribbon cable ZIF socket.
Be sure you are prying up on the hinged retaining flap, not the socket itself.
Remove the motherboard assembly from the rest of the device.
Peel the black silicone cover off the back of the D-pad.
Open the 3DS and orient it so that the bottoms of the buttons are facing upward.
Use your finger to push the D-pad through its hole in the upper case.
Remove the D-pad.

Harman kardon AVR254 – How rest the AVR

Erase a macro
1. Simultaneously press and hold the Activity Button and the Numeric Key or AVR Power On Button assigned to the activity until the Source Selector or AVR Settings Button lights.
2. Press the Activity Button to erase the macro.
Resetting the Remote
To reset the remote to its factory defaults, simultaneously press and hold the TV
Source Selector and the “0” Alphanumeric Key. When the TV Button re-lights, enter the code “333”. When the TV Button goes out, and all of the Source Selectors flash, the remote will have been fully reset.
Processor Reset
There may be instances when you wish to fully reset the AVR 254 to its factory defaults, or the unit may behave erratically after a power surge. To correct erratic behavior, first try turning the Master Power Switch off and unplugging the AC power cord for at least three minutes. Plug the cord back in and turn the receiver back on. If this doesn’t help, try a system reset.
NOTES:
# A system reset erases all user configurations, including video resolution, speaker and level settings, and tuner presets. After a reset, you will need to reenter all of these settings.
# The RS-232 Reset Button on the rear panel of the AVR 254 does not perform a system reset. DO NOT press the RS-232 Reset Button.
To reset the AVR 254, place the receiver in Standby mode (press the front panel Standby/On Switch so that the Power Indicator turns amber).
Then press and hold the front-panel OK Button for at least five seconds until the RESET message appears in the display.
Memory
If the AVR 254 is unplugged or experiences a power outage, it will retain user settings for one month.
