No, your done. Now replace the Y-Main, that's the large one you found the fuse blown on and replace the two buffer boards that the Y plugs into. Those are the two at the far left. The part numbers are on the boards. So that's 3 boards you will need. sometimes they sell the buffers together as a pair which is cheaper. DO NOT buy from second hand resellers. Always buy new when it comes to plasma sets.

2004 chevy impala brake light isses switch has been replaced and so have fuses and bulbs still no lights


Do you know how to test using a DVOM - digital volt ohm meter ? Is there B+ voltage going into the brake light switch ? An coming out when the brake pedal is pressed ? What fuse's ? There is only one fuse for the brake lights !
The BRAKE SW fuse in the RH I/P fuse block supplies battery positive voltage to the normally-open stop lamp switch. When you press the brake pedal the switch contacts close and battery positive voltage is supplied to the left and right stop lamp assemblies and to the center high mounted stop lamp (CHMSL). The left and right stop lamp along with the CHMSL are grounded at G302.
Do you know about the right insturment panel fuse box ?

2004 Deville: I am getting code B 1390 - Device Voltage Reference Input Circuit Malfunction - what do I do?


DTC B1390 -The DIM has an internal battery voltage sensor and a reference voltage. The DIM compares these two voltages via the two battery positive voltage circuits every 300 milliseconds. Do you know what the DIM is ?

Conditions for Setting the DTC
This code shall be set after 10 consecutive readings that the two battery positive voltages differ by 1 volt or greater.


Turn OFF the ignition.
Disconnect the dash integration module (DIM).
Turn ON the ignition, with the engine OFF.
Measure and record the voltage from both battery positive voltage circuits of the DIM to both ground circuits of the DIM.
Compare the two recorded DIM battery positive voltage circuit voltages.
Is the voltage difference less than the specified value?
1 V

Dash Integration Module (DIM)
The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
• Class 2 communication requiring DIM interaction.
• Control of exterior lamps.
• Control of front fog lights.
• Control of the headlights.
• Headlamps on with wiper input.
• Hood ajar switch input w/export.
• Horn relay control.
• Interior lamps incandescent dimming.
• Low side temperature for HVAC compressor.
• Power moding control over Class 2 serial data circuit.
• Reverse lockout solenoid control.
• Steering wheel controls input.

2007 Silverado Classic 4x4 crew cab after parking the vehicle the headlights turn off but not the brake and back up lights How do I repair this problem?


DTC B2550
When the body control module (BCM) receives a signal requesting to illuminate the backup lamps, battery voltage is sent directly from the BCM through the backup lamp supply voltage circuit to the backup lamps.
Voltage for the backup lamp supply voltage circuit as well as the courtesy lamp supply voltage circuit is from the left instrument panel fuse block TBC 2B 15-amp fuse directly through the BCM to these circuits.

What does LD code mean on my whirlpool cabrio washer mean?


Ld flashes when the water level does not change after the drain pump is on.
Is the drain hose or the drain pump clogged?
Is the drain hose height greater than 96? ?
Is the pump running? If not, see TEST #7.
TEST #7 Drain/Recirculation
Perform the following checks if washer fails to drain or recirculate.
1. See Activation of Manual Diagnostic Test Mode, and perform the Manual: Pumps test.
2. Remove the console to access the machine/ motor control assembly. See Accessing & Removing the Electronic Assemblies.
3. Visually check that the P4 connector is inserted all the way into the machine/motor control. If visual check passes, go to step 4. If visual check fails, reconnect P4 and repeat step 1.
4. Remove connector P4 from the machine/ motor control and check resistance values of pump motor windings. Resistance values should match those shown in wiring diagram, page 7-1. If resistance values are good, go to step 7. If winding measurements are much higher (tens of ohms to infinity) than shown in wiring diagram, a problem exists in the motor winding or in the connection between the machine/motor control and the motor. Go to step 5.
5. Tilt machine forward to access the bottom of the machine and the pumps. See Figure 1, page 6-13.
6. Check the resistance at the pump motor. Remove the connector at the motor and take measurements across pump terminals. Measurements should be as shown in the wiring diagram. If winding measurements are much higher (tens of ohms to infinity) than shown in wiring diagram, replace the pump motor. If the resistance at the pump motor is correct, there is an open circuit in the wiring between the motor and the machine/ motor control. Repair or replace the lower wiring harness. If the pump motor windings and machine/ motor control check OK, repair or replace the pump. Be sure to check the pump and tub sump for foreign objects before replacing pump.
7. See Activation of Manual Diagnostic Test Mode, and perform the Manual: Pumps test.
8. If the Manual: Pumps test failed, then the machine/motor control has failed: Unplug the washer or disconnect power. Replace the machine/motor control assembly. Perform the Manual: Pump test.

2003 altima dash fuse blows when i put in reverse and alternator stops working


It is electrical, could be initiated by mechanical (shift lever mechanics are pinching a wire in reverse) or a shorted wire or solenoid in the reverse light system or transmission solenoid circuit. Need a detailed wiring diagram to determine path of circuit for that fuse. That is where you need to start. Try your local library or dealer for a service manual. Look Online also.

Dear Sir:
You have a serious problem:
Do the following step:
1) Test the power from outlet wall.
2) Test it for ground in the outlet wall.
3)power cord test for loose cable.
4) Reset c.breaker from the treadmill
5)test the transformer for voltage input and output(primary and secondary ).
6)Power supply see if there are some component burn or loose wire or melt.
7)See if there are +5 Vdc for digital circuit(main motor board.(
8) Run the calibration software under the Hood motor is the instruction. for diagnose.

Stop Lamp Circuit Description
The STOP HAZ fuse in the IP junction block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to the center mounted stop lamp (CHMSL) and both left and right stop lamp assemblies. The left stop lamp is grounded at G304 and the right stop lamp is grounded at G304.
