Battery dash light keeps coming on very dim while I'm driving, pressing the brake seems to turn it off or attenuate the light. does not light all the time, having no issues with battery failure or power anywhere in the car. it comes on randomly while driving very dim and slowly climbs in brightness until I step on the brake (this is the only thing I've noticed has a direct effect on it. It never gets more than about 1/4 brightness and generally I don't notice it unless it's dark. Turning on AC, lights, other electronic devices doesn't seem to effect it noticeably when switched on.
brand new battery , new refurbished alternator (from trusted source), new alternator regulator assembly, fairly mint NOS engine wiring harness (no signs of crumbling or damage), just cleaned all engine grounds, yes my alternator ground is attached, fuses 13+14/fuse holders appear clean. I applied dielectric grease to a number of connectors in the engine bay when I replaced the engine harness, but I've since gone back and removed a great deal of it while trying to solve this issue thinking that it was introducing additional resistance to the circuits... no change. I am having no performance issues and it's been happening for almost two months now, dash light is only proof that something is odd.
borrowing a multimeter to take measurements in the next day or two, will update. last time I checked battery voltage was looking good. have not measured for drop between alternator and starter/+ battery lead yet. also have not removed cluster in a while to check the bulb, but I did reach up underneath and confirm the battery light connector lead is firmly attached.
I did notice that this issue arose sometime after I installed the new engine harness, however, the cabling looks pretty fresh and I've removed, inspected, and cleaned all the charging system related leads...
this is driving me nuts, suggestions?
thanks!
