Hey guys I got my 270 singer alt in 2 days ago and installed it, since then my battery light comes on and goes off. My front bat is a xs d925 back bats are xs power 3000 2 of them. Now I should mention with the bats installed before I installed the alt my battery light never came on I've checked everything over and over to make sure all was tight and it is I even installed a new smaller belt today and still comes on.my voltage sits at 13.9 at idle when I drive the light will pop on and voltage drops in the 12.5 area my stinger volt meter is back on the amp so I can see what its getting. I have nothing running AC lights music Notta if I brake and start to slow down voltage goes up if I put it in park it shoots up, and I was driving around earlier bat light came on and voltage dropped I turned on the headlights and light went off and volts shot right back up I am clueless here. I also did everything singer said to try truck is a Honda Ridgeline
