Chassis Battery Breaker Tripped

[RVFunlovers]

I go out to the coach yesterday morning while getting ready to roll out.

I start the coach with no issues.

Then I look at the Vega Touch and my chassis battery shows zero volts. I think no way because the coach is running and it just started normally.

I grab my multi meter and the chassis batteries read 12.9 at the batteries.

Then I look and see one of the two circuit breakers by the batteries is tripped. I thought those breakers disconnected the batteries. Maybe one goes to the engine and the other sometime else?

I think I reset the top one but I did it so fast I do not know which.

Anyone know what these breakers really do? And what I should look out for if this happens again?

So far no issues since then.

these are the disconnects for the chassis batteries, but they are also the breakers for the components in the coach on the chassis side. This is to protect the chassis circuits from an overload. Normally the jacks running with lower voltage can trip one of these. You might check your connection at the battery terminals to verify they are tight. That can cause a high amp draw.
