General Car Audio Discussion & QuestionsAll general car audio discussion goes here. Need help installing speakers, headunits, amps or electrical? Having problems with equipment? Have questions about a product, post here.
So my stock 2013 Grand Cherokee came with a 180a high output alt. I decided to have singer recase my alt. Before on my stock alt my charging voltage hot was 14.6, Now with the singer in its 14.1 Why would it have gone down? I know Singer usually has his set points at 14.8. I contacted Mike also to see why. Im hoping the 270a will be much better even though its less voltage. I forgot my vehicle came stock with 180a high out.
Any suggestions? or maybe someone knows why? Im gonna cold start in the morning and read to see where im at. This is testing at the charging point 3 ft away from the alt.
Voltage depends on whatever is regulating the voltage, whether it's internal to the alternator, externally regulated (with something like a transpo adjustable regulator box), or computer controlled like some cars have built into the ecu.
Is the 270a all brand new? You mentioned a 180a alt, a stock alt, and a recased alt.
My singer charges at 14.8 all day and drops to 14.2 full tilt on the bc5500 at .5....
Yea my buddy has a singer in his Bonniville and it works great 14.4v all day... I ordered two singer alts and both charged at 13.7.... And I know adulbirch on here had the same problem with his singer alt he ordered from singer for his Silverado... It must be whatever regulator he use for Chevy 5.3 motor alts
