    I don't know what a driver IC looks like or what the power transisters look like are they the two small ones by the LEDs or is it the same size as the ones I blow up

If the power supply transistors blew out, it's possible that the output transistors have failed (shorted).

If you're going to try to repair it, there are likely 2 blown driver transistors near the driver IC (TL494). You must check them. If they're blown, the new 3205s will blow out again.

Power seat has lost power, right side power windows lost power. Can not find the fuse or relay.


there is a bulletin at gm site in regard to this problem. check the wiring near the parking brake ratchet teeth for damage, also check under the drivers seat where the seat bottoms out wiring could be pinched there or the drivers side door sill.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1734688&psdid=1058&evc=sm#ss1-1734688">Condition/Concern:

There have been reports of either the MBEC 1 or LBEC 1 maxi fuse blown intermittently and unable to locate a short to ground.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1734688&psdid=1058&evc=sm#ss2-1734688">Recommendation/Instructions:

If after normal diagnostics no shorts can be found the below items have been reported:
  1. <LI type=1>"MBEC 1" Maxi Fuse 50 Amp (SI Documenticon1.png ID # 1242532). If no shorts are located on circuit 642, inspect circuits 1340 after the "Rt Door" circuit breaker 25 amp and circuit 1440 after the "Seat" circuit breaker 30 Amp (SI Document ID # 1242687).
    • Inspect circuit 1340 shorted to ground near the right I/P support bracket.
    • Inspect circuit 1340 or 1440 shorted to ground on the support bracket for the I/P relay block.
    • Inspect circuit 1440 shorted to ground under or in either front seat.
    • Inspect circuit 1440 shorted to ground near the parking brake pedal assembly. The short may only occur if the parking brake pedal is depressed.
  2. "LBEC 1" Maxi Fuse 50 AMP (SI Document ID # 1242532).- If no shorts are located on circuit 42 inspect circuit 1240 after the "Lt Door" circuit breakericon1.png 25 amp (SI Document ID # 1242687).
    - Inspect circuit 1240 shorted to ground near the parking brake pedal assembly. The short may only occur if the parking brake pedal is depressed.
Note: Replacement of the circuit breaker is needed if a short to ground is found on circuit 3, 1240, 1340, or 1440.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Scion xa driverside door switch wont unlock 2006


That's in all prob the switch itself. If you can, open the switch panel & test if you have power & ground w/ a test lt as U move the switch back & forth, if OK, U need a switch. if no power or a bad ground-electrical short. sounds like a switch or the connection. Good luck Frank M (if elec short & U cant handle it, take it in.

How do i fix short on one of my headlights on my 97?


If you had a short, you would have already done some
testing to come to that conclusion

A short usually is a wire in need of repair that has rubbed through
& is touching metal.

One side of you car has metal & fluids & the other wires
Both sides are part of your electrical circuits

I purchased an old Realistic TRC-431 CB. When I turned it on it worked fine, the mic was keyed then the lights went dim and stayed dim. Now the lights remain dim. I checked the two output transistors...


The problem is with your power supply. There should be a big round transister on the power supply this is the power transister. It will be mounted to the power supply case. Replace this transister and try to operaste your radio again. Make sure that the power supply you use is at leat 7 amps or the radio will not operate properly and you will possibly blow the transister again.

My marantz SR 7400 suddenly shuts down or goes into protect mode shows code CKPWR5


Most likely you have a speaker short, you need to check the ohms on each speaker disconnected from receiver if they are 8 ohms they should be close to that on the meter no more than a 1 and half ohm varience to what the speaker ohms says on the back. If they are ok you need to disconnect speaker wire from receiver and check for a short in the wire by connecting ohm meter leads to ends of the speaker wire you should get no reading if the wire is good. If this is all good you have a bad output transister in your receiver, but i dout this is the case because these transisters normally short to ground and blow a fuse. Hope you solve your problem good luck

2000 Jeep Cherokee #7 10 amp fuse


You will have to check the positive wire of the wires that go to the parking and side marker lights for a short to ground.Check the easy things first like the bulbs for these lights.It could just be a shorted bulb.You can remove one at a time and see when the fuse stops blowing.You an get a short finder from a part store and save the trouble of getting a bunch of fuses.Hope this helps.Good luck.

My Whirlpool refrigerator trips the main breaker of 40 Amps


A refrig cannot pull 40 amps in defrost , unless there is a direct short in the defrost system ( timer , heater , bimetal ) . I would use an extention cord ( for test purposes only ) , and try a different plug . Sounds like the circuit breaker is weak . In defrost , the MOST you should get , is 6 amps . This will not throw a 40 amp breaker . If you have an amp meter , remove the back refrig panel behind the refrig , and connect to one of the power cord lines (just not the green ground ) , turn into defrost and check the amps . This will tell you if short is in refrig , or weak breaker .
