I need some guidance/advise from the members that know more about this than I do.
Being my rockcrawler is drivable and moves under its own power it's time to work out some of the bugs.
Currently it has the stock alternator out of the 1988 Chevy suburban, 90 amps if I remember. I'm having the problem of killing the battery with just the essential items running. Last summer with electric water pump, ford tarus fan, and transmission cooler fan it will kill the battery. I've got a single Odyssey battery in it and was planning on installing a second one.
I've thought about dual alternators but I don't have the space for it in the engine bay.
My electrical list is as follows,
Electric water pump - 50GPM 6amps
Ford Tarus fan - 90-100amps (at start up from my reading)
50 - 60 amps (running)
Power steering and transmission oil fans - 13.5amps each
5 front & 4 rear 55 watt lights - 4.6amps ea
2 - 3" LED brake lights
2 - 2" LED backup lights
5 - analog summit gauges
Warn Powerplant winch with air compressor - 94-451amps
Obviously the winch will suck the battery down and the alternator will charge it back up.
I've been looking at mechman alternators and XS performance batteries but they aren't cheap. I've got a few options,
240amp - $349
270amp - $449
370amp - $749
XS1400 battery - $260
From talking with the salesman he suggested the 370amp alternator, 3 XS1400 batteries, and possibly a voltage regulator. I don't feel 3 batteries is needed, just 2. If I were to get the 370amp alternator and 2 XS1400 batteries it would still be $1270; not including shipping. I know you've got to pay to play but I feel that's alot of money for electrical; I still can't get over the alternator prices.
Anybody out there deal with alternators before or have something else I could do?
Thanks in advance,
Yellowchevy
