Ok, how do you tell the difference. Two large post, not labeled. How the hell do i know what one is positive and which in negative? and which one gets the jumper to the starter motor.

I'm getting pissed off. when i goto start my car after a swap, the starter will click once and the battery cables get warm/hot, but only of the route leading to the starter.....

Help please

one has a "+" the other has a "-"

seriously?

there should be a minimum requirement before anyone can work on a car!! Everyone attempting any kind of engine/electrical work SHOULD at least know the basics of HOW TO USE A MULTIMETER!!

Simply set the Vmeter for DC volts and touch the two terminals with your leads. You'll get a positive reading if your positive lead in on the positive terminal. You'll get a negative reading if your positive test lead is on the negative terminal.

red is + black is -??? if you've hooked it up backwards, you most likely toasted something.

I am not sure what you are asking... Would you please explain further? (I am not getting the same story as these guys apparently did.)

It seems that you are mentioning the two posts on the solenoid for the starter.

If this is so, the wire to the motor goes on the one towards the engine, and the one to the positive battery terminal goes to the post furthest from the engine.

The negative battery cable connects to the engine block.

(If I misunderstood the qustion, please disregard this answer.)

NoDOHC, I'm sure that's what he means. The other two posters should re-read the subject of the post, especially phoenix7, since he's being so smart.

OP, attach your positive jumper cable to the post where the long black wire attaches to the smaller diameter cylinder (starter solenoid) beside the starter itself. Also jumper the small pin on the solenoid (where the thin black wire with a 1/4" connector is) with a wire to the jumper cable (this is like turning the ignition to start). Make sure the car is safely held with the parking brake or wheel chocks and in neutral.

Hahaha....laugh it up. I know very well how to use a multimeter...thanks.

I'll be nice, and assume I didnt explain well enough.


Black is not negative, actually its positive. Good work champ

And it was hooked up backwards for a longtime and certainly did not fry any of the wiring. However, I am unsure if it fried the starter.



Alright, it goes like this. Crashed my JDM FC into a wall while racing. Swapping everything to a Canadian S4 NA. I'm using almost everything from my right hand drive car. So wiring harness included. Now I had a friend helping me remove the the engine and harnesses. When removing the charging system harness, he did not note or label things like i had done. And he cant remember how it went together.

Therefore, when i went to hook up my starter, I'm looking at it. I see two post and two large wires and a small wire. And 1 ring that goes from one of the post to the starter motor.

Ok, so when i first try it, i goto hook up the battery, i just tap it against the battery terminal to make sure, and it sparks like a mothafucker. My solution was to disconnect the starter and try again.

No sparks now, next i add a terminal, tighten it, then tap the other against the starter, when i found a combination,I assumed it is correct.

But now, when i try to start the car, I get 1 click and the cables are hot. Now, I relocated the battery to the cabin to make room for charge piping. I used 4AWG stranded and phase taped it.

I assumed that one of the post is positive and the other is negative. But is sounds like the other goes to the engine and the negative goes to the block. Can someone confirm this.

And the starter solenoid isnt a problem, there is only the one spade, and I'm certain that is correctly connected.

My other major question is regarding the jumper. If you removed the starter, took it out of the car, there is a very short, low gauge (big) wire, that seems to fit on one of the post.


....
And i think i just figured this out myself....lol...That short wire goes to the post closest to the engine, positive goes furthest from the engine, and the negative goes to the block....can someone confirm? I'm going to try this right now.

I'm to used to A/C and building wiring where everything is labeled and there is always a hot, neutral and earth. Car wiring is strange. lol

Silkroad, you're on the right track (road?)... All the terminals with bolts are positive (basically) powered, the ground is the starter body.

(+) current goes to one side of the solenoid, and if (+) power is fed to the small wire the solenoid closes the circuit to the starter like a switch, current goes to the other terminal on the solenoid and to the starter, through it, and to ground.

NoDOHC

yeah, that is what I was trying to say, the solenoid is like a contactor, it closes a contact when voltage is applied to the coil. The two bolts are the contacts, one is connected to the battery + while the other is connected to the starter motor +. The negatives are connected all the time through the engine block, the positives are only connected when there is voltage to the solenoid.

The worst thing that could be done is to connect the battery positive to one of the long posts and the negative to the other (this would short them together when the ignition switch is turned to start.) I am not sure, but this might have been what happened to you.

I sure hope you get it up and running again (I am sorry to here about that poorly placed wall.)

MidnightOwl

Didn't you post a video of that happening (the accident)? And the shot was like partially blocked by a truck or something? That FC was pretty sweet, too bad though.

SilkRoad

Thanks guys. Yeah, i knew it was a coil. I was just being retarded. My bad. lol Fack.

But i got it working, whole new set of problems now, fuel pump isnt turning on, hard wired it and it still didnt start. Time to look at some relays.



Indeed. did you not see the good video?





haha enjoy.

phoenix7

my bad for the smarie pants, i get what you mean now. Many apologies. I'll read your NEW detailed description and reply in a bit.

Yikes! I don't even know how to comment on that.

How about this:

ouch, dude.

and about your fuel pump, if you actually mean you hard wired your pump then what do relays have to do with it? hard wiring implies you wired it so that there are no doodads in the circuit between its power source, the pump, and its ground. so if that's what you did, it sounds like your pump is bad or your pump sock is severely clogged to the point that your pump won't work.
