I have cummin isx i have batteries icon on dashboard. I changed batteries same problem my powerdrive 3000 kw innovator can only run a laptop lol. If i turn on the printer for example it would restart and go crazy it would run the printer but every time i print a page inventor restarrt it self. I run a test using the power drive app. Batteries result came good. But alternator result came bad. So i went and bought me new alternator after 2 hours under the sun at the truck stop i managed to install the new alternator. Installed the belt and now its doing the same thing. Poor power with red battery icon on dashboard battery . Oh
Bad alternator but its new ?

i'd start by making sure ALL cable connections at the batteries are clean, and tight. then i'd check all the ground connections for clean and tight fit as well.
you have to actually remove the cables, one by one, clean them by using a battery terminal cleaning wire brush, and reinstall. wiping the top clean is NOT a clean connection.
it "does happen" that a new or rebuilt component can be bad out of the box.Diesel Dave and rollin coal Thank this. -
First before you do anything, get a good inverter, a pure sine wave inverter, and pitch the chinese junk one.
AIMS is a good inverter.GYPSY65 Thanks this. -
New part does not mean the same as it did when we were kids
Many new parts are just as bad as the one coming off the truck but an alternator should be able to be tested off the rigW923 Thanks this. -
