added Singer 270a alt but voltage is lower?

[cocoleveo7686 10+ year member]

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.

My singers charged at 13.7v... I didn't like them... It all depends on what kind of regulator he uses

Possible PCM issues? Depends on regulator used I'd assume.

I guess its the Reg

180a seems to be pretty common in vehicles today. My last 2 cars had a 160a and a 180a respectively. I think my girls Kia Soul has a 160 in it IIRC.
