Hey all, Need to make sure im covering all my bases when I start this diagnosis.
I started my truck this morning, nothing special. Checked my voltmeter, battery is sitting low, which is normal because it usually rises after starting.
My voltmeter goes from 8-18 red on both sides of that, and has normal in the center. Usually when running it sits at “L” now it sits at “N” on normal
So I sit and watch it, nothing happens, first thought is my gauge is funky. Turn the truck off, turn it back on and it struggles to start. Battery stays low.
I drive 30 minutes to work battery doesn’t change at all.
Here is what I know to check based on experience and haynes manual:
Mounting bolts for alternator
And thats all i really know to check.
Now, I wonder if the HVAC system is pulling extra, because my coolant temp was reading kinda low, turned on the heat and it went up some. But the battery didn’t drop, but my fans fent minda weak and heat was never really there. Could I have a short in this system? Would that cause it or is that a separate issue?
EDIT: I started my truck, voltage held. Just not charging. Using my power windows drains on it a little but it seems to bounce back from it. Could my battery have a bad cell or the like and thus it won’t charge to where it used to?
