1999 f350 4x4auto. Ok here is the problem. intermittently on starting it cranks slowly, then when it starts the volt gauge is very low. after idling for 1-15 seconds the volts jump back up to normal. after this it may start ok and not have this problem for a couple of days. I am going to check the grounds tomorrow. Any ideas???
thanks

The gauge is below normal for a while because the glow plugs are still on and drawing quite a bit of power. How old are the batteries?

Batteries dead this morning.

Charge the batteries and have them individually load tested . If they pass start looking for bad connections .

after you have the batteries checked crawl under there and check the starter i had almost the same problem with mine and it was just the starter loose

One was bad, parts america replaced both under warranty. Works great. I was a little surprised because of the intermittent and I wen ahead and check all of the connections they are/wer all tight. I notice that the truck runs better now.

Can low/weak batteries cause performance issues? Probably with all of the electronics.

Yea , bad batteries can cause performance issues for sure , improper voltage to everything .
