I think it would be risky, plus running 3 batterys seems harder and more pricey than an alternator. Plus if u had 2 or more hooks at one pull our electronics plus all the pumps and what not would drag it down a lot I would think.
I don't know what the computers draw really.
I know alot of the duramax motors start alot quicker and easier than our motor.
I don't really have accurate numbers on the amount of juice we draw in a pull due to the lack of track time we've had.
I think you would definatley want enough to run two hooks without charging. If you have multiple events/classes you may need to.bring the generator which also adds cost.
Its not so much the cost. Its one less thing to go wrong. One less thing the belt is tied to that is trying to drive your cp3.
Wonder if you could hook up a meter to record power usage at an event.
Were slowly getting the tractor ready. Haven't had anytime. Never really got a winter inly like 20" of snow and none ever stayrd longer than a day, and we've been busy in fields. The transmission should be about done. Getting some faster gears. Looking for some better tires right now with less bite and more of a 45* bar for less hop. Still gotta get the new Turbo kn there too.
