Batteries in my 89 vandura g2500

Asked by Marie Mar 03, 2018 at 06:56 PM about the 1989 GMC Vandura G2500

Question type: Maintenance & Repair

I'm pretty sure I need a new battery in my 89 g2500
vandura. It seems to get drained while sitting in the
snow. Is it possible to start the engine with the
second battery in the back that runs the lights and
stuff?

1 Answer

That would depend on how the batteries are set up but probably not because the back battery is most likely isolated so that it only runs accessories.
