    Thats very technical and needs qualifications , but if you insist, try checking the fusible resistor first after replacing the fuse, make sure you're using the correct value for the components

I water blasted the motor & then dryed it with compressed air but under load it wont rev & misses & dies no power jst wont drive ?


Hi Gary:
I'd be guessing that there is moisture inside the distributor cap.
Try taking it off and giving it a good air blast and wipe out.
Cheers.

When i turn my car on my cd player is full blast i cant find where to fix it


I want to know if you still can volume it down. If don't then your volume button sw for down was damaged.If still can, your cd player's memory is not functioning. Check the wiring of batt. memory back-up wire from the player, this must be connected to unswitch power supply. ( the power supply is always "ON")

Protron TV Died Tonight


It looks like the power supply failed on your TV.
You might be able to find a power supply for your TV for around $125.00 plus shipping and handling.
