just installed singer 270a large case but its lower voltage?

[cocoleveo7686]

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.

Even with the little voltage difference, the 270 will be a much more capable alternator. I'm not familiar with that vehicle, but seeing as it is newer. A lot of new cars have PCM controlled voltage which means the cars computer will control the voltage, not the alternator. So it would not matter what the alt is set for.

I wouldn't worry too much about where your voltage is at until you start playing. Pcm might be a factor.....also not familiar with that vehicle. Check to make sure your grounds are tight as well. Did you ground the alt frame?

is this at idle or driving.
