CHECK your grounds... Pics

As some of you may know, I've been chasing electrical gremlins for a while. I THOUGHT I found every ground and cleaned, etc...

Well, I was wrong. I didn't realize that there was a ground behind the passenger headlight as well. My tip-off was:

I washed the car, then the headlights started dancing and the light under the hood was mysteriously working... This was the second time this happened, the only similarity was there was water present each time.

I unbolted the headlight (as best I could) and voila...

...


I hope this is all of them...

Does anyone know where this side (pass on 87 n/a) routes to? I have gotten as far as the radiator. Does it just go to the other side?

What was rubbing up against the wires? Was it the headlight opening and retracting, or other? Can you tell?

It did not appear that the light rubbed the wires and caused this. When I accessed the wires they were safely out of the way.... HOWEVER.... A carfax reveals an accident "involving the front of the vehicle" under 500 bucks. The light cover was painted "gold paint underneath".. So I think I have the cause.

When wet, the headlights spin continuously and other things mysteriously start working.

I think you have rats. Rats with a penchant for copper.

That's nasty man.

My next major project is exactly what you're doing. The main ground off the battery is missing 1/2 it's shielding.

ONLY PUT IN RECOMMENDED FUSES look!

This all started from the PO putting a 30 amp fuse where there should be a 7.5. If your fuse is blowing, FIX the problem, don't put in a bigger fuse!

I'll try to post another pic.

HOLY SH|T... It is WAY worse than first realized. This wire is melted ALL the way up to the fuse panel. I am looking at a MAJOR repair. It has to be 10 feet long.

I have to get an entire wire harness for the lights and ignition from the fusebox back.

Fortunately there is a porsche 944 in the junkyard about 4 miles from my house. I am going to go and see if I can get something tomorrow.

I am so bummed out, however, I did find the cause of a lot of problems.

I went to the local electronics store here and bought some amazing 4G wire (black and red) and re-ran the ground (to the block) and the positive to the starter, then from starter to alt. If you look in the pics you can see the thick red wire. That is the new + cable. It was a lot easier than I thought it would be.

Let me know if you need any advice.

They were in a sheath, I kept tracing the burnt wires and they led me all the way to the fuse box. I pulled the sheath off. I had no choise as it was melted on the bottom the whole way up.

I was just going to say... those wires should be in some kind of wrapping, but SoCal beat me to it

On another note, I'm re-running my + and - leads on my 951, as well as the Alternator-Starter wire, running some #0 for the battery wires, and some #2 for the alternator wire, very good upgrade for everybody IMO (Hence the Iceshark kits).

My oh my! If the wires burnt like that on the open runs, I'd hate to see what some of the connectors at the fuse relay box look like! I just went thru my project car replacing the entire fuse/relay box, and a ton of relay sockets, and misc. connectors, and short wire runs do to "creative" wiring done by the PO, and because several fuses were over amp fuses than should have been used. The pins into the relay/fuse blocks were burnt up into the inside of the block. Look the relay/fuse box over really good.

Actually, took the bull by the horns and took the whole thing out and inspected. There is only one bad wire... Thankfully.

The PO put a 30 amp fuse where a 7.5 should have been.

IF THE FUSE IS BLOWING - THERE IS GENERALLY A REASON...

I can hear the idiot now....

"Wow, it blew the 20 amp too, I'll try the 30. Yep, looks like that did the trick. Hey you smell something?"

Idiots..

I have to say I couldn't pass it up... I saw it on the acura board ( I have a 95 integra w/ 200k ) and I just had to have it.

Brings a grin to my face still.
