Battery Relocation Help (starts, then doesn't)
 
This week I moved my optimum Red Top to the passenger side rear fender well.
I used 1/0 (aka 0 guage) from the battery to the starter post, from the same starter post I ran 4 guage from the starter to the back of the alternator, from the back of the alternator I ran 6 guage to the positive Junction box (pink box) I grounded the car in 2 SPOTS the rear and from the block to the bodies from rail (up front of course)

Here is what is confusing?
When I try to start the car the first time it starts FINE, then I kill it and try to start it again maybe a few seconds or after about 30 seconds later and I hear the fast clicking sound (starter.)
This car is my daily driver and I need it by this weekend, does anyone have any suggestions??

Is your alternator charging the system? I know my dad in his older firebird had a problem where it would not charge. How many volts does your battery have afterward?

T/A KID Mar 22, 2007 05:07 PM

I don't know I haven't checked, I need to go get a Volt meter and check the Alternator. What did your dad DO???

I'm kinda confused by the whole thing. You should have the alternator run back to the cold side of a kill switch. If you don't have a kill switch (which you need to be track-legal with a remote located battery), then I guess you can run it to the front post like you mentioned.

I don't know what you're talking about as far as the alternator wiring goes though. Basically the alternator has two wires. One which 'turns it on' known as the exciter wire which is very small gage. The other runs to wherever you want to send the power to (battery, starter post thing, whatever). You should only have a single wire coming from the alternator.

Draw me up a schematic of what you're talking about and I'll take a look.

That has to be a ground problem. Make sure the negative side of the battery has a very good ground in the back. This happend to me one time and I made a better ground for the battery and it solved the problem.

T/A KID Mar 22, 2007 09:52 PM

Well I am not worried about being legal at the track since I rarely go so, this is mostly just a Fun street car. I can come up with a diagram showing how I routed everything, Hell I can get real pics if that would help its on the lift right now.

Well I possibly thought that as well but it starts fine the first time and then doens't a feel seconds later. If I wait about 5 minutes it cranks right back up fine again, lol.
In the back I can get a Pic but I took a Grinder to the metal and got it down to bar metal??
Tony did yours start the first time then not the second like mine.

Thank you guys for helping me so much.

I second the Ground Issue ;)

I'll also say it is a grounding problem. Bob

+2 on the ground issue. But I think your wiring may be wrong. The positive wire should be coming from the positive battery post directly to the alt. Here is a diagram on how it should be wired. If you are not running a kill switch just overlook that section but this should help you get the jist of it.

Ok guys here are some pics (excuse the dirty engine me and her has some miles between us) and I am not worried about being legal at the track with a Cutoff switch, this is just my fun street car. If I ever get kicked out I get kicked out a lot of our tracks are pretty cool though.

Here is the pic of the battery located in the rear where you can see where I grinded the rear panel to take it down to metal, my finger is pointing to where I ground the negative cable in the back.

Here is an actual pic of the Ground I connect it to

Here are a Few pics of where I Route it under the car

Here is where I connect the 1/0 guage from the battery to the starter and then I connect the 4 guage from the starter to the Alternator

Here is the 4 guage wire going up to the back of the alternator from stater

Here is the Second ground. Its from the Block to the frame

I had to get a voltage regulator. Have you driven it around yet?

Mar 23, 2007 12:51 PM

Might wants to pull those grounds and make sure they are clean. No paint, bare metal.

T/A KID Mar 23, 2007 01:37 PM

Pulled the grounds and cleaned everything up and I put a New starter on the motor (autozone LT1) The old one passed ever test but I got a new one anyway. Went to start the car and it didn't even start this time???????

My old man told me to run another cable from the battery to the motor???? I have never heard of anyone doing this, I may try to run another ground from the stater bolt (connects to block) to the body???

87Lt1Monte Mar 23, 2007 01:45 PM

Did you ever find out if you were charging that battery? When shit clicks several times in a row every time ive heard that it meant low charge. Are you sure you have an "Exciter" wire to allow the Alt. to charge the system?

Bitemark46 Mar 23, 2007 02:39 PM

The problem is solved it the wire goes from alt to the pos battery post. They way you have it is that you are trying to charge the battery through the starter. -Mark

T/A KID Mar 23, 2007 10:05 PM

I have a 6 guage wire coming from the Alternator to the Positive Junction Box if thats what your asking.
Took the battery to see if everything was ok, past with Flying colors

T/A KID Mar 24, 2007 02:10 AM

Noticed the New starter has Copper style Threaded connection end at it is Striped :mad:. Plan to take it back tomarrow andget another one or possibly get my money back and buy something different :mad: . The bolt would turn when I had everything on it but would not Tighten, When I went to start the car my brother wiggled it and it acted like it wanted to start???

I changed my ground in the back to the larger bolt on the quarter panel, the one right behind the seatbelt holders when you do the delete for the rear seat.

Does it sould like I have enough Grounds???

T/A KID Mar 24, 2007 01:59 PM

I went to get some 1/0 guage (about 14 feet) and ran it from the starter along side the positive wire and went right to the Block. Startered the car and it cranked right up, Then I killed it and I then started it right back up, I killed it again and it didn't start the 3rd time then I decided to try again and it started right back up. All of this was within about a 25 second span.
My old man told me he thought it was fine and that I should not try restarting it so much one after another so I suppose if it starts first click everytime don't worry right?

I do have one question ON the same post where I mount the 1/0 guage from the battery to the block I have a 6 guage wire from that same post to the body. I have some left over 1/0 guage that I am thinking about putting there in its place what do you guys think???

Again thanks for helping guys.

T/A KID Mar 25, 2007 05:48 PM

Here is the new setup,
0 guage from battery to starter
0 guage from battery to block (Ground)
4 guage from starter to alternator
6 guage from alternator to junction box
4 guage from block to frame (Ground)
4 guage from starter bolt to frame (Ground)

Car starters about 4 times out of 6. Any thoughts guys???

76LS1BIRD Mar 25, 2007 07:58 PM

I made up this block to make moving battery easy.
Everything is hooked to the stock cables
This is bolted in the bat. tray

I also added 200A fuse on - cable.
