no changes to the system... drove home in the rain. no issues running the lights and wipers. the dash gauge dipped low, but no pulsed cutting out from the edic
So I pulled the EDIC and its controller. Controller looked clean. EDIC unit had crappy grease in it and some corrosion, nothing crazy.
Re-installed it all and it still does the pulsed cutout.
my next thought is that the alternator is going out, battery shows its getting 14.25v, so IDK. next stop...
EDIC and fueling was my first idea, but it build revs fine, and with out the electrical load its fine. is there a EDIC relay under the dash?
also the dash gauge dips with the clicking from under the dash
Am currently investigating both EDIC and wiring
My HJ75 grew a issue need help with, under electrical load there is a clicking from under the dash and the truck lurches with it while moving. The electrical load while it was clicking was wipers and headlamps
Resent changes new battery single BCI group 27 AGM vs two wet cell group 27, and...
Have you checked your hot tubes that run to the heater core or tried flushing it?
I did a coolant flush and ran some stuff to clean out all the cruds and it made my truck run like a sauna
it didn't seem to harm anything, the evapo-rust company has long track record with chemical rust conversion. the first time i drained the coolant out of my HJ75 you could see some chunks of rust, after the chem treatment there were no large bits in any of the fluid.
if you have done three flushes all ready have you looked at doing a chemical conversion with something like Thermocure. if done right it will clear your galleries in one run.
