Please forgive me for such a dumb question (voltage related)...

[Knightmare]

I searched for the better part of an hour, and I couldn't find the answer, so please don't shoot me! lol

I let my m1009 sit a little to long between cranks, and now she doesn't start, dead batteries.

Would a 12 volt battery charger be able to get the job done?

I know one of the batteries operates at 12v, and the other at 24v... So which one is which?


I've heard you guys say 2 vehicles could get the job done (of course I can't find the thread now), but are they entirely necessary? Could I do it with 1 car, and the charger, or maybe just the charger?

I'm a real rookie when it comes to this stuff, but everyone has to start somewhere.

There is more than one solution. Here is one:
Disconnect the battery cable in the appropriate order.
(should be stenciled on the underside of the hood)

Attach battery charger to one battery and charge.

attach battery charger to second battery and charge.

Reconnect battery cables in correct order.

start truck.

Actually both bateries are 12 volt. They are run in series so the power is 24 volts out of second battery (2 x 12 volts). Don't try to jump with 12 volt, just take both batteries out and completely charge each 12 volt battery seperatly on 12 volts then put them back in.

The front battery operates at 12 volts and the rear battery by the firewall operates at 24 volts. What are you doing letting it sit, they are meant for driving

BTW don't feed it ether if you can't start it. Good luck!

You can charge the batteries individually without disconnecting anything. Just hook the cables up normally to each battery but not across both and you'll get 12V. Just don't let any clamps or anything touch metal on the rear negative and you'll be fine.

Joe nails it. Just charge each battery, without disconnecting. + to + & - to -, when you are using a 12 V chargers. If you have two chargers, you can charge both at the same time. Make sure all connections are clean and tight. Take care with the grounds, that they are good.

If you had a 24 volt trickle charger hooker up at terminal block would that work with the isolated grounds?

Yes, it will work that way. Same as a solargizer.
