While upgrading various things on our ( new to us ) boat, something jumped out at me & specifically: We have twin 210 HP Cummins with what I was told were twin 120 Amp alternators, but the charging wire from each alternator looks like # 14 AWG maaaaybe # 12. Is that typical ? Out of common sense, I was going to change them to at least # 6 or # 4 but one is going to be tough to access with my waistline ..
So again, should I get into this thing ?
How would I find out what size the alternators really are ?
Thanks in advance .... Frank B.
