Is Chassis Battery Charged From Pedestal?

[jaycojon]

I would like to use the radio in the dashboard while we are in Florida for the winter. Does it only get charged when the motor is running or will it charge from the pedestal like the coach batteries?

You should have a Battery Isolation Module which allows the chassis battery to be charged from the pedestal if the voltage drops below a certain level.

You might want to contact Jayco and ask for the BIM schematic for your coach. It could also be named a BIRD (Battery Isolation Relay - Delayed).

Granted, I'm coming at this from a Class C, but I had to put in a module to charge my chassis battery from the pedestal/on-board converter/charger (Trik-L-Start).

But in my case, I believe the dash unit is powered from either the house OR the chassis. When the ignition is off, power comes from the house. When ignition is on, it comes from the chassis. This also may be a side effect of the dash head-unit also acting as an entertainment hub for the entire rig...?

At least, that's what my experience has been. I've never fully tested that (like by disconnecting the chassis batt)...

Quick test - turn off the battery disconnect to the house battery and see if the radio comes on without the ignition turned on. If it does then I suspect it is just directly wired to the engine's battery.

A voltmeter will tell you if the engine battery is charged from the converter. If you have the 2 way isolator then the engine battery level will go up when the converter is charging provided the battery it is low enough to trigger the isolator. You may have to drain it down with the headlights to reach the trigger point.

I have a power outlet voltage monitor that I watch to keep tabs on the engine battery since my unit only has the one way isolator.

Unless they went backwards there is a diode system that allows the radio to function off either battery.

To answer the question from a fellow Precept owner. Yes.

No problems. My coach sits for months and I use the radio often. I'm plugged into pedestal. Chassis battery keeps charged.

That's what I was trying to say... You said it much better.

Thanks to all who replied to my question. This Forum is fantastic and I appreciate all the info I have gotten on many topics.
