So I have been stumped all weekend on my 05 stroke. New alt, new batts? Wondering if it could be the FICM. So the batts will show 13.5 as soon as I turn the key The FICM comes on and the batt volts drop to 12.1, and when I crank it the volts drop to 10.2 and that barely gets the starter to click. I've got fully charged batteries and even hooked my wife's truck up with jumper cables. I tested the FICM's volts( 4pin) and it shows 48.2
Should the volts drop that low by just turning the ign on, all acc or off. Need help!
Thanks

Electrical issue have always been my weak link.
So I did a continuity check on the pos cable on top
The radiator. It is showing -2
If this helps someone help me out.
