power loss

[LayinLow99]

Sometimes when I'm coasting my voltage will drop and go back up over and over till I gas it again. I think it only happens at night when I have my headlights on but I may just not be noticing it during the day. My alternator and battery have been replaced not too long ago so I don't think that would be it. Any ideas?

same thing happened to me, turned out to be corrosion and battery acid crap in the cable ends where they goes into the battery on both + and - sides... i cleaned them with a wire brush and sprayed some anti-corrosion spray on em and the problem went away.
