Dual batt. setup, starter battery is only a couple weeks old, will be load-testing them tomorrow to be sure.
Replaced the belts and re-tightened them all, so a loose alternator belt isn't to blame.
I don't think its the alternator itself, as the past couple days its started out cranking real slow and then increased speed, as if the alt. was providing a little juice.
Then tonight instead of picking up speed and finally firing it just drained the battery and died. Jumped it, brought it home, tightened the belts (alternator belt was a bit loose), jumped it again, drove a good 30 min at highway speed, electrical components were strong and healthy... tells me that the charging system is good at least. Brought it home and killed it, waited a few seconds and started it up again... cranked much slower than normal but fired after a good 5 seconds of cranking. Waited 30 seconds and killed it. Went out for 30-45 min, came home and tried again to make sure it'd be on its feet for work tomorrow... cranked a few times and died
. From how it felt after I killed it and started it I'd guess that a good 10-15 seconds of being off would have drained her enough to prevent cranking.
All this has me thinkin parasitic load... a short would most likely prevent starting regardless of the voltage or amps running through, whereas a parasitic load only consumes so much. Anybody second this? Disagree? Where should I begin my search? Any other possibilities?
Thanks in advance.
