Ive got a '92 and its got a JVC deck installed. Ive also got a B&M shifteron whichthe indicator light is powered by the stereo ignition feed.
I just had the heater core replaced and the guy that replaced it tore the wire off the indicator light- no big deal since I had another light.

I hooked it up and everything worked but then I shifted thru the gears to make sure the indicator still worked.

Then the light and the stereo stopped working.

The deck will accept cd's and eject them but will not turn on otherwise. Once it accepts/ejects a cd it turns back off and wont work otherwise. No clock, no lights, nothing.
There's power going to both sides of the fuse (checked with a test light). I also checked the voltage at the fuse and its 12.14 volts on each side.

The factory deck will not turn on either so Im pretty sure its not a bad stereo and its not the deck to car adapter harness since the factory deck doesnt work either.

I dont see any broken wires or other visual problems. Ive been trying to figure this out for over an hour now.

I dont understand what couldve gotten messed up. Any ideas on what to check?

 

check your fuses make sure the bright one didnt just blow a fuse on you/

 

The fuse on the back of the deck works and the other fuse works because the horn still works and theyre on the same fuse.

 

Make sure it is connected to the exact same power wire and that there is no insullation missing

 

Its connected right. The weird thing is that I can power the deck up using a jumper wire off the battery to the yellow power wire and it works fine but then it doesnt shut off. Once I put the shifter light on the deck shuts off though.
