I am having a battery charging failure from my alternator on my 99. I have been eliminating everything on the wiring diagram found here:
This diagram im noticing is a little different than my car not sure why but it says the ecu is on the right side of the dash, no where does it list the ground in front of the diff. and a few other deviations.
I have tested for continuity on all wires except
(i have not been able to find in my car based off of my schematic)
1. to the ecu from the alternator
2. to the alternator from the ecu
In my car at least one of these wires trace back to the fuse box in the engine bay and not straight to the ecu like the diagram would suggest.
I have done the following already:
brand new battery
reman alternator that has been bench tested properly
all grounds have been taken apart and cleaned
I have a newer megasquirt pnp 2 that i hope is not the culprit of my alternator failing and would like to rule out everything else first before purchasing a new one. (unless there is a better way to bypass the ecu regulator)
Is there a better diagram i should be using for my car to track down voltage drops in the line or do i need to bite the bullet and start looking into a new ecu?
Any help would be awesome i have an event coming up in a few weeks and need to get this motor broken in asap
