The factory battery was 650 cca and 8xx 850? ca.
I guess ca is a warm cranking amps. Putting the
battery on the "computerized" load testers at
Autozone or Advanced Auto yields a "good" finding.
I even double cycld the load test one day.
Did not check out starter motor contactor.
The intake is clear. There's visible carbon, but
not any thicker than 1/16".
I'll see if I can pull the starter this weekend, and
go after the relay/contactor on the starter.
Does anyone have a cranking amp figure for the starter and motor?
on a warm engine, I see 225-275 amps nominal. On a cold
(20F) engine, I see about 450 A.
