jeep pcm bypass for "real" alternator

Re: jeep pcm bypass for "real" alternator
Jeeps are very known for bad grounds. They get real sneaky ones too
like the alternator bracket is no longer grounding to the engine block
type of sneaky ones.
I look for these by walking a multimeter looking for the voltage drop.
I start with the engine running and headlights and heater fan on for
circuit draw and get a volt reading at the battery 'posts'. I then
leave the meter on the battery positive post and put the negative on the
alternator case. I should have almost the exact voltage.
I would suspect on yours I would find a difference so I take the
negative meter probe and put it on the cable clamp at the battery post,
then on the cable, then on the engine block, then on the alternator
bracket, then on the alternator case, then on the body of the vehicle.
If I find a voltage drop at any of these points, I have found a bad
connection.
I also walk the positive meter probe along leaving the negative on the
battery post. Same thing, from the post to the clamp then the cable
then the cable's other end, then the bolt it is on.
If I was to swap a real alternator in, I would go for the AC Delco one
the CJ and GM uses. They are everywhere and easy to get parts for. It
is a 'one wire' setup but runs best with 2 wires coming to it, one to
the battery and one key switched trigger to turn it on.
I have no experience wiring the others but would figure the main output
from your alternator would just feed the regulator. The regulator would
need to be wired properly, but a schematic for it should outline it or
knowledge of the old Ram.
You might run into trouble with emissions though.... That check engine
light has to work and it will likely be left on with the alternate
alternator.

ok heres the deal.. im getting a high field coil voltage (around 11)
all the time.. lights, wipers and heater blower on or off makes no
difference.. but charging voltage is always low. so that points me
back toward the alternator, only problem is I had the alt. tested at
autozone before i installed it.. so now im stuck again.. i guess ill
take the alt. back off and have them test it again... if it comes
back fine what would be my next logical step to getting this thing
running? thnx again for the help j

ok heres the deal.. im getting a high field coil voltage (around 11)
all the time.. lights, wipers and heater blower on or off makes no
difference.. but charging voltage is always low. so that points me
back toward the alternator, only problem is I had the alt. tested at
autozone before i installed it.. so now im stuck again.. i guess ill
take the alt. back off and have them test it again... if it comes
back fine what would be my next logical step to getting this thing
running? thnx again for the help j

You are under the impression 11 Volts is 'high'?????
Did you check the ground paths like mentioned earlier?

Re: jeep pcm bypass for "real" alternator
Did you make sure the battery is connect to alternator's battery
terminal, and that it's trigger wire turns on with the ignition, with a volt
meter?
