Voltage low. Good battery, new alternator.

[diego06310]

Got 95' Astro Van has new alternator and good battery.
Tested the battery twice came out good.
Change the alternator twice in 1 week.
Worked fine at first after running. Not sure if front and back a/c
and turning headlights are causing the battery light to turn on
and the voltage to drop low. Sometimes voltage gets normal but then drops again.

Could I directly run a wire from the positive of the battery
to the alternator?

Any reason why I got this problem?

Dirty battery connections. Ground to block. Body grounds. Common hot behind the battery is melting and getting ready to go out.

^ all of that.

Because the connections to your starter solenoid look that one on Leeann's van, before she repaired it.

Im haveing the same problem I just replaced the alternator and battery. I had my tester on the battery trying to see what was going on and its only readying a little over 10. its pretty frustrating
