I have an 86 Dodge ram 3/4 and I'm having charging issues. My alternator went out about a month ago. Bearings and such. Purchased a new one and truck worked fine. I use it for mainly plowing. A couple.weeks after it stops charging again. So I check and was getting volts from all three terminals on the back of the alternator. So I assumed it was fine and purchased a new voltage regulator and everything seemed fine. Plowed the driveway and the other day started the truck several times no issues. Go to plow and suddenly starts losing voltage. Plow won't go up . Wipers going slower. So I check the alternator and I get volts from two terminals but not the main one. It flashes 19-20v for a second and won't read anymore till I keep poking n rubbing the multimeter leads. So I bring the alternator in and get it tested. They say the alternator is bad. Failed all the tests and putting out 30+volts so I put a new alternator in again and start plowing and soon I'm dead again. So I do some checking and getting 12 or so volts out of two terminals and none on the main again. I do some research and come across a video on regulators and the guy shows using a multimeter reading ohms from the two leads from the voltage regulator. His read 1.7-1.8 saying that's about 14.6 volts. I check both my old and new regulator and I get 17.6 ohms. I recheck the alternator and this time I'm getting 8-9v and watch it slowly dropping on the main terminal . So after all this long ass message lol. Sorry about all that or if it's confusing. I'm wondering if I need a new alternator and new voltage regulator. My alternator is just a stock 60amp. Or if I can upgrade to a different setup or bypass anything or burn it to the ground as an option?
