First of all, I'd like to say I appreciate your help. I know this is a bit of a shit storm, but any advice would be appreciated.
I have been Knee deep into this project for a couple of years now, working on it at random when I have time. The car hasn't been driven yet and has only been run for 5 minutes half a dozen times. Turned out to have lots of random issues and I made the mistake of doing a motor swap and turboing it before fixing them. So I'm now on a megasquirt base tune and I'm trying to figure everything out and get it running enough for my tuner. Been hitting so many roadblocks it ridiculous. It seems like a dozen teenagers owned this car at some point because its a rats nest in too many places to count.
Anyways,
I hadn't touched the car in a couple of months and realized that I killed my battery. So I bought a new battery and found the drain from fuse 21 when the ignition is off.
Question number 1: Is it possible that I killed those si batteries because random stuff on my cluster doesn't work.
Now here comes the real mistery. I found out that my alternator wasn't charging my battery after I did the motor swap. So after doing some testing, I bought another one at the junkyard for $30 and swapped it in last night. Afterward, I checked the voltmeter and it seems to randomly pop up to 13 volts kinda rhythmically, but not enough to maintain the proper voltage on the battery. After I got done tinkering with this for a couple of minutes I go to turn the car off and it doesn't turn off! At first, I was terrified, because I hadn't bled the coolant yet, so I was concerned it was detonating due to heat, but it was running for a very short period. So I waited about 20 minutes, turn it on and off quickly, no problem. Turned it on again waited 1 minute, didn't turn off. Same issue. So I was curious if it would run without my battery hooked up and to my surprise, it did run while my battery was completely unhooked.
I know this is a long read, but I'm baffled.
Plan of attack:
1. Right now my game plan is to check the grounds and alternator connections after work.
2. Figure out if my cluster is interfering with the car not shutting off and if the SI batteries my be part of the problem.
Any words of wisdom here guys?
