I have a 2001 f350 7.3. It has been cranking slower and slower over the last few days and this morning I was lucky it turned on at all it was cranking so slow. I checked out the voltage on the batteries and they checked in at 12v each. I have noticed that the mirror lights were flickering yesterday, very lightly, but was flickering.
I need help guys, im down to my last truck and I need to get this one back up.
Thanks for any and all help
