ground locations...?

eclipse27 · 10-14-2007, 06:50 PM

Is there a site that will show me where all my grounds are located. Mainly all that apply for taillights/turnsignals/gaugecluster.

No. Even the FSM won't always show you that part unless it's also got the full wiring location diagram (half of mine don't, just the schematics).
I actually have the 2002 FSM and I don't see where it lists any grounding points in the rear. Only spots under the dash and some in the engine bay. But your tail light ground I believe is very close, just pull one of them and follow the wires. Shouldn't be hard to locate the ground.

Still trying to figure out my problem. My taillights are grounded well. I just dont understand what could cause the gauge lights to flicker/ and the brake lights stay on while the headlights are on. Also when i use my turn signal the oppossite side comes on and doesnt blink... Whats that sound like bad circuit/short?

**SirGCal** · 10-15-2007, 06:30 PM

sounds like the circuits are shorted together somehow...

Im dumb so i appologize for all the dumb questions but i hafta get this running withing a few days. What should i begin to look at / do? Is there a circuit unit i need to look at? Or what

Well, if it was working fine, then you did some work, then it's not working fine; it's almost always where every you did the work... So I'd look there obviously. But from the little you've told, it sounds like the turn signal circuit is shorting out to the brake circuit somehow. I'd have to start with a serious diagnositic of the wiring to see where things are crossed up. Starting with a continuity test between parts of each circuit to see where/if I can get a match to help locate where the problem might be. This isn't going to be an easy solution if you don't find it where you were doing work, but I still bet it's there somewhere. It's the only solution that makes sense.

Thats what i've been doing for the past couple of days. I checked everywhere by the gas tank i've looked over and over at my tail lights and everything was fine. I've tried chasing things down. You dont think anythings fried do you? I guess if it wasnt working at all then it'd be fried.

**SirGCal** · 10-15-2007, 08:02 PM

well, there are different levels of fried.. Could be something melted internally shorting something out without frying completely. If you're stumped, it might be time to take it to a professional to troubleshoot. It's extremely hard to diagnose something like this over the internet obviously since there's so many possibilities.

Wheres the main unit or w/e were everything meets up? I've tracked my lines, but i haven't looked at like relays or anything. I assume there behind the dash?

**SirGCal** · 10-16-2007, 08:04 AM

Ya, it's all part of the master harness. It looks like your tail/brake wires run down the driver's side then under the rear of the tub to the passenger side. There doesn't seem to be a main unit where everything groups. Turn signals come from the blinker circuit while brakes come from the brake lamp switch which seems to be right off the pedal box while parking likes come from the headlight circuit...

Could a corroded pigtail at the brake lights cause this cross shorting you mention?

**SirGCal** · 10-17-2007, 04:35 PM

possible....
