Replaced Batteries, what now?

[OldSarge]

When I went to start my Jayco Seneca, I had no power...….nothing, zilch! I took the batteries in and found they would not hold a charge so I purchased 4 brand new ones. Put them in, proud of myself, jumped in the drivers seat and...……..no power zilch!!!

Anyone have any idea what may be going on....?

Thanks

Start looking at fuses, breakers, and switches. There should be an in line fuse or breaker near the battery as a safety measure. Most bigger rigs have a cutoff switch near the batteries for when the rv is parked. then look for the breaker panel and look for fuses and breakers. By the way, did you check that the batteries were actually connected and in proper order. Loose connection??, Dead out of the box battery, & were they charged before use??
Then check that the ground to the frame at the battery and the one at the fuse panel are both good. With four batteries brand new there should be some charge even if low when new.

What year Seneca? that helps us to guide you in the right direction.....

If it is the M2 chassis, those batteries are under your drivers seat. Under the cab in the compartment below - you have to open the door to access that panel.
