bre2ts Posted January 23, 2012 Report Posted January 23, 2012 With the car on check the charging voltage coming off the alternator. If its low like you were saying than the alternators bad. When was the last time you topped off your battery? Feedback 1 | Feedback 2 you win some, you lose some
LoudBimmer Posted January 23, 2012 Author Report Posted January 23, 2012 With the car on check the charging voltage coming off the alternator. If its low like you were saying than the alternators bad. When was the last time you topped off your battery? It's 13.7v Battery was fully charged little more then a week ago.
bre2ts Posted January 23, 2012 Report Posted January 23, 2012 Hmm 13.7 is a little low but not too low. low for car audio. What's the batteries resting voltage? It's sounding more and more like it's the alternator than anything. Feedback 1 | Feedback 2 you win some, you lose some

It's sounding more and more like it's the alternator than anything. batteries resting voltage is around 12.4-12.6 The biggest problem I saw so far is when I turned my music up to fult tilt and voltage dropped to low 12's, but once I turned it off, it stayed at 13v for a little bit and then slowly started to move back up to 13.7/13.8. Befero, it would jump back to 14v.
n8ball2013 Posted January 23, 2012 Report Posted January 23, 2012 disconnectyour batteries from each other and test them individually. 12.4 -12.6 is low low low. get it up over 12.8 at the lowst.

bre2ts Posted January 23, 2012 Report Posted January 23, 2012 Your d3100 should have a higher resting voltage than that, it seems like your alt has had enough abuse and needs to be replaced. It'll probably continue to go slowly or just stop charging all together. With my experience with XS batts is they usually rest above 12.8 Damn you n8 nijaing me like that Feedback 1 | Feedback 2 you win some, you lose some
sprkn_ranger Posted January 23, 2012 Report Posted January 23, 2012 Yup I'd bet it's the alt. good time for a HO alt I guess! Check out my build log! 4 Havocs in a blowthrough http://www.stevemeadedesigns.com/board/topic/187506-sprkn-rangers-blowthrough-build/

n8ball2013 Posted January 23, 2012 Report Posted January 23, 2012 scratch that disconnecting thign. I thought you had one in front one in back. Its your alt then. 400 ampsof current draw on a 120 amp alt will do that.
