I admire your patience and tenacity.
Reminds me of me on funky computers.
I do not have the board you referred to. Just a Dell laptop in use. Other three are desktops. No spare MOBOS.
Did nothing on van today.
I can certainly replace the alternator myself. Just did the 88 Caravan.
The 3.3 has 130,000 miles, so the alt might be ready for the trash, as you say.
Voltage is very important for a computer, too, so I am down with your obsveration.
Will do the key dance. I have a code book around here someplace.
Have already installed new fuel pump and filters, as I said. Commercial computer read-out said weak fuel pump and that was all, so naturally we thought the problem was in it.
Still have the metal flooring ripped back for access. Makes a great bed for robots. LOL
Will get back to it tomorow.
Thanks, Tenacious!
