'93 GT
So I'm just finishing up my project. With the new motor I've hidden the wires and relocated the battery out back using buffhomer's (sp?) method with a cut-off switch. Used 1/O from cut-off switch to solenoid, and from battery + to opposite side of the cut-off switch from where the solenoid wire is. I then have 2ga from the battery nagative to the quad shock bracket finally there is 4ga from the alternator to the 150amp circuit breaker and then 2ga from the breaker to the back of the car and attached to the same side of the switch as the + battery wire. All connections are soldered using the correct size lugs for the cables. I also used welding cable throughout.
So here are the symptoms I'm currently experiencing:
When I first fired up the car with the new motor I had the stock battery and everything appeared to be charging correctly. After a couple starts and right before we were supposed to load the car up to go to the dyno I noticed that it was charging at maybe 10 volts at the most (second line on the gauge). The first dyno went well but it kept getting more and more difficult to start. A friend had a known good alternator so I installed it and fired it up. The gauge showed that it was charging correctly. I gave the car a rev and the gauge dropped back down to where it was previously (around the 9-10 volt mark). So I figured I'd take it up to Vato Zone to have them run a battery/charging test. On my way up there, which is maybe 2 miles at the most from my house I see the gauge jump up to where it is should be (tad bit over half way) for a few seconds then jumped back down to the second mark. By time I got to the store the gauge was pretty much at the bottom. We tried to test but the battery was to low and the alternator wasn't charging at all. So the guy jump starts me and I head home. I made it about half a mile before the car died. Obviously it was running off the battery and that had finally died. So fast forward to when I finally get it home. I looked at the circuit breaker and it was tripped. I try to reset it and it wouldn't stay. Pulled the breaker off the car and it was fried.
So I went and bought another breaker and a 3G alternator. I tested the yellow/black, green/red wires which all checked out (1993 Mustang---Alternator not charging----PLEASE HELP - Mustang Forums at StangNet). I made sure the battery was fully charged and started it up again. The gauge went up to a little bit above the half mark and all looked good. Took it for a spin and maybe half a mile from my house the gauge went back down to the second mark. When I got home I checked the breaker and now the new one is not tripped but I can't push the button to manually trip it like it is stuck in the non-tripped position. I checked all the cables and non of them felt even close to warm. I drove it a little yesterday and the gauge stays on the second mark and hasn't appeared to be running strictly off the battery...yet. I have checked resistance in all the cables and there isn't any open grounds.
I bought a 175amp fuse yesterday to try but I was hopping that someone here might have seen this before and could point me in a direction of some sort before I start comparing the advantages of selling this thing over digging through the miles of wiring.
Thanks in advance!
