Okay.
3 months ago I installed Megasquirt with my own harness.
2 weeks ago head unit maybe the amplifier to the sound system would flicker (causing loud pop in speakers).
1 week ago car starts randomly shutting off when braking for an intersection (lose electricity). Every powered object on the car would go dead for random amounts of time, then just turn back on, after a millisecond or 5 minutes and all would be fine until the next incident.
3 days ago, I go to pull the car out of the garage, successfully unlock car with alarm remote, hop in turn on megasquirt and zeitronix (on one channel with MPI relay) go to crank the car and all dash lights go out and everything shuts off.
Thinking short in my custom wiring harness right? immediately remove the whole harness and turn key to on and have no power.
I have a relocated battery (to trunk) with 0 gauge wire running up to the factory battery terminal spot and the 5 gauge or similar ground connecting to the shock tower in rear.
check voltage drop and continuity across those and all is well.
I disconnect the power at the factory battery terminal fuse box and find I have one continuity to ground, at the white with red stripe wire which goes to seat belt, sunroof (don't have) and defroster, then also to the fuse box under the dash with fuses I believe 6, 13,14,15,17. I pull fuse 17 and continuity to ground is no longer present. Leave fuse 17 out and put the rest of the car back together and still have no power. Here I throw wrenches, kick the neighbors cat, and begin to cry and masturbate using my own tears as lubrication.
Today I try to repeat the test with fuse 17 and it shows no continuity to ground... WTF?!?!?!
Is this a short? Is it a bad ground? Where do I start? Should I just strip the whole car down and put a carb'd V8 Hemi in it?
Please help with some direction...
PS the batter is fully charged.
PPS amp draw between the neg and the neg battery post was to the tune of .017 amps
Thanks. Erik
