Hey guys greetings. New member. I'm hoping somebody on here could help me. I have a 2001 gu 2. With stock head unit. I hooked up my egt gauge and was using a test light to make sure I had power going to the gauge. As I was pulling away I hit positive and negative on the gauge. The gauge still works fine. Although my radio is not working now. There is no power coming from that wire so I switched to a different wire for the gauge. But now my radio screen does not come on and play radio. The button lights Still work and ejects cds. But no playing. I have checked every fuse they all have power inside and out of the car. Both sides of the fuse socket. And pulled the cabin fuse box out to check for burn wires and can't smell anything either. Any help would be greatly appreciated thank you for reading

G'day, welcome to the forum,

Radio unit has/should have 2x powers supplies, one from battery via fuse no 56 (10 Amp) in the engine bay RHS after the battery the so called memory backupĀ  and another from ignition switch ACC or ON position via fuse no 10 (also 10 Amp) inside the cabin above accelerator pedal. e.g. bellow example

I'm not sure which one you have as there are numbers of different models/types with specific harness however it appears that fuses numbers and locations are the same. I have looked up up to 2004 models and the location and numbers are the same.

Also a lot of electronic devices like radios/tv/cassette players have extra glass fuses inside the units, the holders are soldered to the circuit board somewhere inside. Shouldn't be that hard to have look if you are sure that you have positive voltage on those two e.g terminals (pin 6 and pin 10) or just probe wires until you locate two voltage sources in the plug.

I wish this happened to me that way I could finally upgrade to dual din 6" multimedia "Ebay special" without regret, LOL.

Regards
