Battery Configuration

[vangrady]

Guys;

I have a 1990 Marlin 30 with four batteries. Could anyone tell me if Grady wired the two house batteries in parallel, series or separate? As far as I know, they would still be in the factory configuration.

Many thanks!!

Factory wiring was two seperate batteries to one battery switch which then goes onto the 50A circuit breaker in the battery compartment.

the entire Grady manual for the 1990 marlin which shows the schematic can be found on the Grady website.

Your 50A breaker shoud look like mine. It is marked House in the following photo. Follow that wire up to the switch and you will know which one selects the battery for your house loads.
