Sparks Flying!!!!!

[thetech0922]

Ok i have a HUGE problem...When I try and hookup my cables to my battery sparks start flying from the battery posts!!!! I have juust completed a entire engine rebuild on the car. NEW EVERYTHING as far as on the motor and such. I even bought a new wiring harness for my car because mine was cut and missing connectors like crazy. I had everything already to go to start the car and i just installed the battery and i was hooking up the cables and it just started sparking and continued to spark. I don't know if i have something hooked up comletely wrong in the wiring harness that is making it have too much of a load or what??? I am using a JDM ecu which i dont see why that would be causing it to do that or what. I dont even know where to even begin looking for the problem... I tried just hooking up the positive connector and leaving the ground off to see if i was grounded somewhere else?? But it only does it when i have the ground and i touch the possitive connnector to the possitive post sparks go everywhere!!! I have not even started up this new engine ANYONE with ANY GOOD IDEAS i would be willing to try anything at ALL. IS there any WISEMEN out there?!?!

i would start by checking to see if you pinched any wires when you the motor back in

 

[thetech0922]

I ran the wiring after i put the motor in so i don't think that is the problem..I have a major short somewhere and i mean MAJOR..:'(

 

[turbotalon31]

can you post a pic of your battery wiring and alt. wiring close up

You mean "are the any" ok back on topic;

Did you leave the start power laying on the tranny/frame? Your starter harness is the issue here, nothing else would be able to spark for more than a fraction of a second without melting.

You hooked up a main ground to a positive,or vice versa., and it should be easy to figure out. Post up some pics and we may be able to point it out.

OK i have finally have some pictures for you to look at. ok the first one is a picture of the back of the starter and the wiring harness that goes to it. 1. is where i am assuming that the power wire connects to the back of the starter and 2. is the connecter that goes to the solenoid.

3. is the ground wire that is in the starter harness. I have relocated the ground with the other red wire that you see connected to it.

4. Looks like to me as just a ground wire that comes of the positive side and grounds to the body. That plate fits under the other two plates that are on the positive side. Is that in the wrong place?? its been so long since this thing has been together and run that i have forgotten alot of where things go and connect too.

5. Seems like an dumb-ass question but i will ask it anyway..do those two connectors go together the one end that i am not holding is off of the starter harness and the other is off the body harness. They click together nicely but i just wanna be sure before i fry something else and end up in a world of pain of tracking down wires and such....

The starter ground wire goes from starter to one of the bolts that you screw into the transmission case. Standing at the passenger fender, it will be the starter mounting bolt on the right.

In the picture you have marked as #4 at least one of those is a positive wire. The one with the larger flat plate normally sits between the fuse block and battery terminal shown in the picture with #3 The other wire I can tell because I can't see what the wire colors are. Same thing for the wire marked #1. It could the the positive feed for the starter or the ground that should be bolted to the starter mounting bolt.

# 5 is the plug that interfacesthe starter harness to the engine harness, its for the reverse lights and the starter solenoid.

#4 the flat bigger one goes the the battery positve, the other one goes to where?


I made this pic , hopefully it helps.

That pic has one flaw, my bad. I think on second thought hat the small black wire from the plug that is how going to the neg should actually be a positive, from the battery positive...not positive now. Doesn't change anything for you though .

Ok i just have one more question. 4. does that just ground to the body somewhere through a bolt? I think i have it figured out now but that is my final question..for now...thanks everyone for all of your input

 

[sniver]

Depends, I can't tell what it is for sure. If it is indeed a ground, and the one end is bolted to the top left bell housing bolt, then that gets attached to the negative battery terminal and a seperate small ground cable goes from the negative battery terminal to the firewall.

ok. so i should be able just to ground it to the body and i should be fine?? it is on the positive side of the battery.... Ok i just hooked up everything by the way of the diagram.. I am still getting sparks?? If i take the cable in picture number 4 out, I dont have any type of sparking when i try and hook up the positive side...is that cable supposed to grounded to the tranny rather than the body??

No offence, but perhaps you should consider taking the car to somebody more qualified before you burn your car down.

I mentioned a ground that goes from the trans/block to the neg battery terminal, then to the chassis. And you go connect the positive to the chassis????

At this point I wouldn't be suprised if you have already done permenant damage...

I'm not to sure how this can easily confused. Ground is the chassis,engine,trans,and battery neg.

Positive is the starter stud,fuse plate,battery postive. you don't plumb your water(pos) like right into the drain(neg) do you? No you make the water(pos) go through a faucet (starter)first, then to the drain(neg). Maybe this will help you better?

Ill go investigate my harness in a minute, and see if I'm overlooking something, but I know I'm not. The starter harness falls into place, you'd have to modify it almost in order to be able to connect it wrong.

The one on the left in picture with #4 should be one of two wires: it either goes from the positive battery terminal to the 80A alternator fuse in the main fuse box OR from the 80A alternator fuse to the B terminal on the alternator. You should be able to check where it goes by tracing down where the other end is hooked up or leads to.

I made it easy to follow.

2 black w/ yellow striped, 1/4 inch thick wires go on the negative terminal.

3 wires go on your positive terminal.
* the large tab in the one pic w/ all the fuses (no color, metal)
* the wire that goes to your starter (black w/ red stripe 1/4 thick)
*the wire the goes to your fuse block 80 amp fuse (2 white thinner wires)


And like 19eclipse90 said, ther is a main positive that goes from your alternator to the 80 map fuse.

 

[thetech0922]

Yeah..i figured it out. That number 4. goes to the side of the fuse box. I don't think I have fried anything yet, or at least i hope not. If i fried anything oh well it will be ok
