Glad you got it figured out! So now the least you can do is get another picture of all your light output for us with those vampire killers
lol. you werent even british. had me going haha
It sounds like a ground issue for most of your problems.
Hmmm
I would also replace the small gauge ground/negative stock wire. The one that connects the negative post of the battery to the body. It's about 6" long.
this sounds like a ground issue right off the bat.
you say you have 3 batteries and its probably that the car is running off what might seem like only the rear battery because after you load test and check the front two which seem to be connected correctly.
so maybe whats happening is that your WHOLE car is running off a really dead rear battery which you think is connected but may have lost connection to the front bank.
so easiest way to know before looking for an issue is to remove the rear battery ground connection completely and try to turn on the ignition again.
if you have no dash lights off the bat then i can bet that is the issue.
ive seen this happen to a friend before and we were stumped then later realized the entire car was running only off his secondary battery because the fuse blew between the front and rear bank.
so check it out and i can almost assure you if this is the issue your rear battery is completely shot and you will have to buy another.
nothing against you either but if i remember correctly your batteries in the front for both positive and negative you have used the same red colored wire.
this is fine but if anyone else works on your car or you make a mistake thinking one wire is positive versus negative this can back fire on your later.
try to get a black wire maybe or different color at least to help easily differentiate between positive and ground.
instead of adding or locating grounds, try remove ALL grounds attached to your battery bank and run straight the only necessities.
ground to block, to frame and to body.
positive to alt, positive to fuse box, and STOCK positions..
start there and try again if problem still persists you have a major problem.
thanks gerdo. that ones been done long ago. i rerouted it down to the frame. im starting to ground everything straight to the frame to rule out possibilities
i was thinking we could be friends...until you said MAJOR PROBLEM lol
its just gotta be a ground somewhere. it acts like a ground.
