Hi,

My only suggestion is to go to your nearest Radioshck or similar store, as they are the people that stock this kind of gear.

Assuming the radio connects to the RS amplifier, the harness is as follows:
From fuse 13: PNK or BLK -> PNK/LT BLU -> PNK or BLK -> PNK/LT BLU -> radio (!)
From fuse 20: RED/WHT -> radio
From fuse 10: VIO -> amp
From radio: ORG and BLK/YEL to interior lights
From radio to amp: DK BLU/RED, BRN/RED, DK BLU/ORG, BRN/ LT BLU, VIO, DK GRN or DK GRN/WHT, DK BLU/WHT, BRN/YEL
From radio to pwr ant: DK RED/GRN
From RS amp to:
R. door: LT BLU/VIO and LT BLU/DK GRN
R. front: ORG/BLK and ORG/RED
R. rear: TAN/BLK, TAN/RED, TAN/DK GRN, and TAN/VIO
L. rear: WHT/DK GRN, WHT/VIO, WHT/BLK, WHT/RED
L. front: YEL/BLK and YEL/RED
L. door: LT GRN/DK GRN and LT GRN/VIO

Uniden grant lt transmit and receives normally but when i key up on AM the AM power regulator gets hot quick i changed out the driver and final and replaced the regulator still does the same thing and it...


Sounds like a "short" if it affects modulation + power. Try to inspect board with magnifier for solder bridges, and bad resistors. Change a few resistors near back with new ones. take out slugs near back finals like L10 or L20's not sure if its same as Uniden Pc68xl. but try that. I found turning L19 up to top gave great Modulation. clip D9, Sread coils 1/16 inch in back. Try to get lower carrier. Carrier does not mean anything much. Modulation is what you need. With less Carrier it may cool down that chip. It may be too wound out.

Blown fuse and reverse polarity diode


Check around the pcboard where the dc goes to the board, sometimes the foil will burn. Also chec the transformer, Chec that one of the wires did not come off the plug in the back. When you replaced the protection diode did it blow again? If not keep checking for opens on the pc board. When you said it was dead do you mean no lights at all or no tx and rx?
