Hey new here. I have a 1995 Tahoe 2 door 350 tbi. I've gone through 4 alternators in the past year. the first one was from age. The second one was a faulty alternator. The 3rd one was from power steering fluid spraying on to it. Now I'm on my 4th one. About a month ago I was sitting at a red light and I felt the truck shutter, I didn't notice anything so I went about the rest of the day. Within the last week I've now notice the truck shutters like its going to shut off but the volts come down with it. the volts now fluctuate when driving from 14-12. I've hooked up a multimeter to alternator and battery and both say 14.5. I've had both of them tested and they are both fine. I've added new frame to engine and frame to body grounds and I've put an all new positive battery cable (starter to battery to alternator) it seems to be getting worse. it only happens after the truck is warmed up and only while in drive. new plugs wires distributor cap rotor and egr. I cant seem to figure out why the voltage drops suddenly then picks back up like nothing.
