Well

ny test is not going to happen

cant get the pcm connector on the secondary alt off.

the primary came off no problem.

looks like this is the end of the diy adventure

was hoping to verify a primary alternator problem and I would of probally replaced it my self rather than do the out of state warranty appt.


anyone have a number at Ford USA I can call to complain?

thanks

question will be did the faults follow the alternator suggesting bad alternator

or

did the faults remain suggesting pcm circuit problem


Why do the male ends of those cables look so chewed up?

The female ends are actual alternator plugs

couldnt find an exact match male end so I bought a plug that was close and peeled back the plastic


the purpose of the cable was just to trouble shoot for a few minutes


couldnt do the test ....couldn’t get the secondary connector off

I called ford service complaint hot line and they took my complaint. they indicated they were going to just send it to the dealership

I also looked at the local dealership site to see if there was a survey link and wound up on a chat with their internet response team. I asked them for a link to rate the 22 feb service response I got and they took my info.....a few minutes later...service manager emails me and says they will find an appt.

so maybe will not have to go out of state after all.

as crazy sensitive as the electrical system is could it just be a bad voltage sensor, no clue if that even exist anymore though.
also wondering if the voltage reading is a phantom reading, have you tried to start and disconnect both batteries and then see what the alt output is?
Grabbing at straws here but I feel your pain.

I haven’t run with both batteries disconnected

i think since forscan shows a gen1 fault, I was more trying to determine if the fault is the gen1 alternator or the pcm circuit to the gen1 alternator

I brought it in to a PA dealership. I live in nyc.

they concluded it was an open circuit (somewhere under pax battery). Message and error is gone....but...I’ve had it for a few days and my battery voltages are runnning 14.8 to 14.9 which seem high to me. Will probally have to bring it in again.

Is this looking like a harness problem again?

Those voltages do appear a bit high. What is the resting voltage of your batteries? I've noticed 14.4-14.6 when my batteries are charging up. Maybe it's possible your batteries are a bit drained and the alternator is outputting a bit more voltage to quick charge them?

I do mostly short trips during the week and on the weekends take a little longer drives so I'll precharg the batteries on a trickle charger then monitor them over the weekend.

my concern is I read that the PCM varies the charge rate depending on the battery state of charge and in the past I verifed the charge rate varied...meaning....after crank up the voltage was mid 14's, but once the batteries recharge (5 to 10 minutes), the voltages dropped to low 14's.

I also know that if I put a surge protector across the battery terminals, indicated running charge voltages never go above 14.5, so that tells me that the 14.8/14.9 stuff that is going on are voltage spikes.

Not getting any warning messages, lights, or codes.

I need to review where I read what the correct charge behavior is and then circle back with the dealership.
