No power to anything what so ever!!!

[d_rock10030]

I know that wiring issues are almost impossible to solve without being hands on, but I was hoping that someone may have encountered the same problem or maybe can point me in a good direction to start! I have a 95 gsx with a 99 4g63t swap in it and for some reason the car is absolutely dead (No dome lights gauge lights not even a ding when I insert the key!) I have tested the power to the ignition fuse in the engine bay and there is power there but that’s all I know to check. The alternator is pulled off right now, but I don’t think that would have anything to do with it, would it? The battery is charged and testing good. I am in the middle of finishing the timing belt job that the previous owner never got around to so one of the cams is off right now. Also, it does not have the cam position sensor on yet. Could any of these things be causing the power issue? I plan on finishing the timing job and reinstalling the alternator on monday so that everything will be in its proper place.

Does anyone know where I should go with my troubleshooting next!!! Please help... So lost and getting a little frustrated!

I am going to ask you a question, did you happen to notice if there was any cable going from the battery to the alternator when you took it off?

 

[d_rock10030]

Yeah there was and there is a wiring harness that runs from the battery to the fuse box in the engine bay.

 

[92AWDHX40]

Sounds like either fuse, relay, or wire connection isnt good, wiring sucks, check your dimmer switch also.

 

[95dsmgsx95]

Yeah sounds like a fuse to me too.Most of the time its something simple like a fuse or a ground.So just check the fuse box under the hood and under the dash and go from there.

 

[d_rock10030]

Yeah thats were I'm at with my troubleshooting at this point. Guess its time to start yanking fuses and going from there.
Now, does anyone know all the grounds that are involved in the 2g eclipses? You see I didn't do the swap myself. this was someone else's project that they never finished that I bought for a grand. Thus Im not sure if all the grounds are mounted properly and I cant find any kind of diagram anywhere... Might have to pull the motor and start from square one. At least that way I'll know it's done right.

 

[H4G64T]

Okay, so you have a wire going from the alternator to the battery, but now you took the alternator out, and that wire is just chilling. So if you need to make a complete circuit to make power and you have a wire just hanging off the battery...how do you have a complete circuit?

 

[d_rock10030]

Took the alt. out to have it tested... its back in now.

check the alternator fuse. i had the exact same issue on my car and that was the problem. i bet you nothing works untill you turn the car on

 

[d_rock10030]

That was the first fuse I checked and it was fine... that’s why I pulled the alternator to see if it tested fine.

Now I feel really dumb guys... So I went to my work to test my alternator and left the bolts on the ground and when I got home one was missing (My guess is my nephew was playing outside and he grabbed one and dropped it somewhere)
Anyways, I have the tensioner that mounts to the bracket and the longer bolt that the nut threads onto, and the bolt that secures the bracket to the block. I need the one that goes through the tensioner. Anyone know what length/thread that is?

 

[gusu]

That is a special high tension bolt. I'd put a ad on here. I have an extra but im not sure if the 1g and 2g is the same. Im not sure if a normal fine thread bolt will fit but it might be worth a shot.

 

[d_rock10030]

Yeah I guess I'm taking another trip to the parts store tomorrow to see what they got. I wanna mount this thing right while I try and find my wiring issue. Thanks for the advice gusu.

 

[Chengy]

Hmmmm I had the same problem before. My car would turn on but none of the lights work at all. Turn signal lights work though. But found out it was just a fuse.

 

[d_rock10030]

Yeah I wish it had any signs of life at all but there aren’t any! none of the lights work not even the hazards But I might have found the culprit to the problem while i was wiring up the alternator for a third time now... went to hook the battery up and there wasn’t a single spark at all when I connected the ground cable. So I traced that back and there was some cheap electrical tape down near where the ground cable bolts to the block. I peeled that back and the wire was almost chewed in half and it was all rusted out. Pulled it out and plan on replacing that tomorrow

sounds like you should clean all the grounds under the hood, check ignition fuse, when that pops you lose almost everything because its like the key isn't on

I've had this blow on me on the interstate and the car just shut off. Took me a couple hours to figure out what happened because everything looked good. Just simple stupid fuse

You wouldnt happen to know the location of all the grounds would you? I can only find a couple and they're all good and clean. I even replaced the main ground running from the battery to the engine block.

Oh and whats the computer under the pasengers seat?

 

[MrKelly]

It's supposed to go from the battery to the firewall, that's your problem. Fix that and you should be in business. The harness grounds are right behind the battery on the firewall there will be four small black wires also a small group for lighting behind drivers headlight on inside of the fender , the main grounds all use the firewall as a common ground, you need one from each to the fire wall: the battery which also goes to the starter, one from the engine block and one from the intake manifold. The thing under your seat is an amp that came in cars equipped with the Infiniti sound system from the factory

 

[d_rock10030]

Awesome so there is a ground from the harness to the firewall and the starter to the battery, the lighting cluster to the firewall. And not one to the engine block? I thought the big main ground wire with the terminal ran from the battery to the block.

 

[MrKelly]

there should be no wires from the battery to the block, the wire from your ground terminal on the battery needs to go to the firewall but it also connects to the trans , not the block. you need a cable to ground the battery and the trans to the fire wall. if you don't know what im talking about ill take a picture of what the wire looks like tomorrow

 

[dsmcrazy2]

if i were you. check to see if the ecu is connected. i've done many swaps and ran into the same issue. all along the ecu was disconnected.

yeah it sucks. I was wooping on my friends c5 zo6 and something in the road kicked up and went under my car as i shifted into 4th, nothing happend but i backed off and pulled over and looked under the car, couldn't see anything, nothing seemed wrong or hurt. we pull back out, i rip through first and second and my wideband starts flashing and the car bogged and everything including dash lights go out. i coast into a dark parking lot with no headlights and check the fuses. the ignition fuse is blown, so i put the power windows fuse or something that was 10 amps higher in and the headlights came on so i start it and it starts and then dies, then i smelt something burning and saw smoke under the hood so i hit the battery cut off and had a friend flat bed it home. next day i look under the hood and give it power real quick and see where the smoke is. piece of something came up and broke the speed sensor plug off and it wrapped around the axle til it rubed raw and cooked about 3 feet up the harness killing power to the car. i had an extra harness to replace the burnt section but what a pain to pull the one in the car apart, mitsubishi uses way too much tape in their harnesses.

Yeah that would be great! Thanks so much for all the help guys!!!

Alright guys, running grounds from the battery to the intake manifold and from the intake manifold to the firewall, battery to the firewall, wiring harness to firewall, starter to firewall, and alternator to firewall. All of my grounds will run to the firewall to create a common ground!

I will update and let you know if this solves my problem!

 

[d_rock10030]

Well folks I re-did all the grounds my own way with 8 gauge wire and I have some good news.... She's Alive!!!! Thanks for all the help and input as to what u all thought the problem could have been. No to finish mounting the intercooler and finish the timing job and she will be ready to hit the road for the first time in 2 years!

Congrats, keep it goin
