voltage no matching to battery bank(alternator not chargin?)


Recommended Posts

Yes- you have to isolate each battery to see if one of them is bad or low on voltage. One may be pulling the others down.

His rear d3100s are fine, they are brand spaking new for the most part (like I wish my batteries were 1/8 the condition of his).

And both of his d3100s read realitively the same. I remeber checking them when they were at my house when I showed him how to recone his woofers, and build a box.

Wish you lived closer man, or I had the spare cash to drive up by ya to trouble shoot this more.

The D3100s may read relatively the same, but if his front is resting slightly above the rear then he would probably need to throw them on the charger. Ive seen new batteries sit for just a few weeks and drop .2 or .4 and need a quick trickle charge. No biggie. :shrug:

brian you know you can't speak for what condition they are in now. If something came loose and he drained the rear batt and didnt know it it could be dragging his voltage down.

well i have an update on my elecrical issue i just charged them and it now read even lower and i checked everything all wires fuses everything my front batt still reads 14.1-14.2 at idle but the back battery barley hit 13volts but i will try 1 or 2 more runs of postive wire from my front battery and see if that helps,

any input will be nice with my annoything problem
