Hey yall, I recently swapped my battery to the front of the car, 88 GT auto, and it has caused a whole slue of problems. my dome lights don't work anymore, they will not turn on ever, my courtesy lights are the opposite and never turn off and to finish it off my trunk release no longer works. Some stuff you might want to know is that they all worked right before the swap, my ajar light has been on since I bought the car (when running) but would sometimes turn off when I hit a bump, and my trunk light used to work by giving the trunk a good hit but doesn't seem to anymore. I spent hours on here but cant find anything so this is my last resort, I re did every ground I could find and added more but it helped nothing, I've already checked the fuses in the box too. Any help? solve it 1 by 1 if you want I just want it fixed, thanks in advanced guys (and ladies)!

Also the voltage gauge is pinned when the car runs, reads right when its not running, but I checked the battery and not running is bout 12.3v and running 14v so it seems to just be the gauge.

You may have checked already...

Check the "batt" fuse. If it blows, the courtesy lights will stay on.

yeah, sadly all my fuses are good to go so it's something more. I've looked for a wiring diagram but can't find one for interior.
Thanks for the help though!

I had a similar problem briefly when I removed the trunk latching mechanism and it cleared when I replaced it. Look for a broken/loose wire in the trunk circuit. Especially look at the grounding strap and wire. Good luck. Maybe you could contact Mary Bara as she was the electrical engineer that oversaw the wiring for the Fiero . (Just kidding!)

what happens if you put the battery back in the tray and hook things back up?
did you drill or cut anything?
i read there was 2 fuse banks, one in the engine compartment.
just going from a simple signal flow of things, if stuff worked before, then undo what you did
and step by step repeat until it goes bad again. sounds like something got buggered instead of just adding
length on existing cables

Ground issues? Did you run the negative cable from the battery back to the engine?

Hope this helps

Thanks for the help! I'll check up on the trunk latch and no I didn't run a ground from battery to engine, when I moved it up front I grounded the battery to the frame and then added separate grounds to ground the engine to the frame. Could that be the issue because it made sense to me when I did it but I'm not electrically inclined haha

Bad grounds can cause all sorts of weird issues. When the battery is in its original location, it grounds to the engine, not to the frame. Relocating the battery up front for better weight distribution doesn't change what the battery should be grounded to. Yes, I know... somebody will come along and say they relocated their battery up front and grounded it to the frame and everything is peachy keen... but IMO it's not the proper way to do it, and it can lead to problems.

I agree with Patrick, the battery should connect to the car the same way it was originally.I ran positive and negative #2 awg welding cable from the front battery back to the original battery conections. I also added a frame ground in the front while I was at it.

Great I'll get the grounds back to normal and let you know!
