Ok, so finished the turbo install. Get everything buttoned up, fill it with fluids and am about to get ready to start it and I go to connect the battery and get HUGE sparks. So, I connected it the opposite way. Hot side first, then negative...still huge sparks.
Here's a little history.
Did the turbo install, installed BSR, and installed SAFC.
I think I had wired the SAFC incorrectly so I unsoldered everything and did it correctly. Everything is well soldered and wrapped in elec. tape. Anyway, I disconnected the ECU and tried to connect the battery again just to see and it still sparked.
Unhooked the alternator from its hotwire and it still sparked.
Took at a look at the starter and it seems normal.
My boost gauge is mechanical. So the SAFC is the only thing I wired...
What could this be????
(Please don't say a "short"...I know that already...please try to be specific if you have any ideas.)

what do you mean huge sparks? the hot is sparking onto the hot wire? i know when i bought my car the person before me had an amp wired up and the hot wire found the chaise...created a fire over the plastic cover of my hot wire. you can check that making sure the hot wires are not grounded. when it did this it killed the car...the way electricity works is it goes the path of least resistance, traveling from the hot on the battery to the speaker wire to the chasie was the least resistance so it did. no voltage to anythign else and it died. hope this may have helped

I don't have an amp or anything like that, but when you put a terminal on the battery (doesn't matter which one) and then you put the second on, the second one sparks big time, like welding notches into the posts.

Sounds like u have a short to ground some where! Recheck wiring and then hook pos first!!

does it continue to spark after you get it all the way on?

Haven't pushed it all the way on, it sparks way too much for one thing. I'm almost positive it will start a fire if I got it all the way on.

umm my battery always sparks when i reconnect it.... its the electricity jumping and grounding itself. Do the sparks continue after you have connected it or is it just a quick spark?
Offline

Daniel




I know it sparks a little when you first put it on. This is not normal sparking, this is major big time sparking.
Offline

Jeff


does it stop though?
Offline

Daniel




No. It sparks the entire time they are touching.

Shaun


maybe your car is just overexcited bc you have a turbo now? lol serioulsy i would check the leads and grounds and make sure everything is where it needs to be

Disconnect the ECM and remove the main fuses then try!
Offline

Rick




U have a bad ground to short or positive somewhere!
Offline

Daniel




I disconnected the ECM. Still sparked. I traced the main wires off the battery and everything seemed fine. I guess I'll try fuses tomorrow. I just don't see what could be causing it since I didn't mess with anything electrical other than the SAFC which wires into the ECM which I disconnected and still had sparks.

sounds like a bad ground then, scrape off some paint from your car were the neg line connects to the chassis and make sure you have good contact there. Or try a new neg line from autozone for like 6 bucks.

Rick




Is ur ignition on or stereo on when u put the pos or neg on the battery??

hhhmm...sounds possible. The car is at my grandparents house so I could use their garage during the install.
If it was here, I'd go try that right now. It could've gotten messed up while I worked or something. I was not delicate in that area.
Offline

Daniel




Nope ignition is off. I guess the stereo could be on, but I've disconnected the battery several times with it on just like it would be now and never had this problem.

Rick




If u can use a test light with pos and neg wire ends hook it up to the battery and touch the neg to see if u have a ground!!

I did that. I do.

Rick




Well maybe u have a huge ass draw somewhere!! like about 10amp or 20amps unlikley though!

Rick




U have probably disturbed something so just relax and recheck!!!
Offline

Daniel




Yeah, I finally got it all finished tonight at like 10 and I think I just got frustrated. I'll go bak over it real careful like tomorrow.
Offline

Rick




Check everything over and then if everything looks good pull all ur major fuses and then see if it goes away then install one at a time to find out what circuit u have a problem OK!!
Offline

Daniel




That's what I planned on doing. I was just hoping this was a common problem or something...althought I've never heard of it.
Anyway, all ideas are still welcome.
Offline

Daniel




Also, I don't think this will matter, but it did happen.
I took the battery out to make it easier to run the intercooler piping and then put it back in.

Oh, and we stripped out one of thos e-torx bolts pretty bad and ended up grinding the head off to get the balance shafts out. So we put in the BSR kit with only 3 of the 4 e-torx bolts. It's still pretty snug and everything so I didn't worry about it.
Again, I doubt this is it but I want to make sure all the information is out there.

i did that. but i bought a new bolt to use. but yea recheck every electrical wire youve ever done
thats why people hate electrical stuff. troubleshooting its a bitch

Daniel




all the electrical stuff I did is unplugged except for the stereo which has never done anything before. It has to be something big I imagine or it would just blow fuses.

ror



um, is the red one going to the positive and the black one to the negative?
i dunno and sorry for the smartass comment, its all i could think of

Daniel




Yes...the battery is connected correctly.
Offline

Daniel




Ok, so here's what happened today.
I look at the ECM and I see that the harness isn't quite plugged in all the way. So I plug it in all the way and that takes care of the sparking.
So, I button everything back up, get ready to start it and it just cranks and cranks.
The instrument panel doesn't work, nor do my headlights/taillights.
The SAFC powers on and everything so the ECU is getting power.
The 120 amp battery fuse is blown.
Do you guys think it was just all the sparking and messing with the battery? And do you think this could be what is keeping it from starting?
I'll try to update any info if I think of it.

is your alternator postive wire hooked up correctly. with the one nut underneath and the other one on top? just a thought if you took the bottom one off for some reason?

You know what...I didn't, I lost that nut..could that be negative?

well the one nut goes below it so the uh harness with the red thing on it fits snug on that or else it bottoms out on the alternaotr itself not the stud. def get a new nut for that and try that.

or all the sparking could've fried something else.

Daniel




I'm hoping it's just that fuse.
The SAFC powering on should indicate that it's not that or the ECU correct?
Offline

Daniel




One more thing, not sure if it matters or not.
My SAFC throttle wire is not wired up because I was going to do the boost hack and haven't gotten around to wiring the map sensor in yet.
Offline

Jeff


nope it is your alternator that is the only thing that is strong enough to blow that 120 amp believe me i have done it numerous amount of times it has left me stranded on OC maryland 140 miles away from my house lol. but yea make sure that power wire is not touching nothing other than the post sticking out of the top of your alt if not then is is grounding itself out on your alternator. also check there should be a little plastic piece that goes on that little stud to make sure this does not happen. make sure everything is hooked up right on your alternator and starter. and make sure they are both grounded and make sure your trans is grounded too.

i blew my 120amp fuse the other day as well, i mean i wasnt putting in a turbo , just doing my headers but still , it was a pain in the ass.
Offline

Daniel




Awesome. I'll check that put today. Thanks guys.

So the good news. It lives.
There is only half an exhaust on the car now though, there is an open o2 sensor port, and it is not held on by any hangars or anything so the racket is awful.
I've noticed so far that it kinda sputters a little, possible the exhaust and open port and such?
I have no o2s plugged in and have srt-4 plugs gapped to .035.
I haven't really reved it that high because of the terrible racket and its kinda hard to tell what's going on anyway.
Offline

RJ



will the studder would be because you have no o2s pluged in. glad you got it going. get the exhaust together and get that 02 together.. unless you wanna buy mine lol... so you can get tuneing and driving the beast. :-) im excited for ya..

I have no where to plug them in.

oh you have no bungs in your downpipe? you should get a couple put in so you can run the wideband and stock o2s + makes it even easier to tune with o2s in
