discharge/overcharge?

sorry if it was hard to read i was just trying to get all the info in there i could think of, thanks for the replies, im gonna do that mad upgrade tomorrow, ill go get the necc parts and change all that over, not sure if it will fix the problem but im sure it wont hurt to go ahead and update that stuff anyway.
trailbeast, i didn't try to add that 10gauge jumper, ill give that a try also tomorrow and see what it does, should i leave everything stock hooked up and just jump that over and see what it does, also that 15.5 volts at the battery terminals is at idle without raising the rpm's.
67dart273, info is very helpful, i will try that stuff tomorrow as well, i feel like the ground to the VR is good as i ran a ground to the battery ground to the VR case but i will ohm it out and voltage drop the ckts.

No problem, and it really doesn't matter that much if you are going to do the Mad bypass anyway.
It would have just given you an indication of what the bypass would do if everything else stayed the same as it is now.
15.5 is a little higher than I would be comfortable with at idle because it'll go higher with rpm's (unless your car idles at 1000 or more already)

Following Del's advice will take some time and patience, but it will also make sure it's right.
He and I have had a disagreement in the past over my using the 30 amp relay where your car had the 20 amp fuse, but my car had a 20 amp fuse there when I got the car and it blew occasionally.
His point was that the fuse or whatever that is used in that circuit should be capable of handling the output that the alternator is capable of (60 amps in my case) but I figured if the 30 amp breaker could handle the normal usage loads then if it tripped it would indicate that there may be a problem somewhere before that full 60 went through the system or to ground.
2 years now and it has never tripped once, even with every electrical device in the car on at the same time.
I do have a lot of LED's in my car though (brake, markers, signals and interior lighting), as well as the headlight relay kit which greatly lessens the amp loads on the cabin wiring and switches.
