Chassis batteries discharge

[Dave&Kacy]

While hooked up to shore power for two weeks, the chassis batteries drained enough so the "idiot" lights would not even come on. I was able to use "boost" switch to start the engine. Doesn't the shore power charge the chassis batteries as well as the coach?

It's supposed to, but often your outgo exceeds your income. For some really dumb reason one of the things that gets cut off is charging the battery. If the house/coach batteries drop down below a set voltage, then the relay will not activate and charge the chassis battery. My people use a device called <span class="ev_code_GREEN">Trik-L-Start</span>

Dave,

It would be helpful if you could add the year of your coach to your signature. Now that I asked for that, depending on when WRV changed to the Vansco system is what counts. Their literature shows that 2004 was the first year, but they probably started the switch in late 2003 model year. If you have the Vansco system, then your "big boy" relay is probably bad. Look for light 19 on the Vansco module to be light when the house batteries are charging. Do a search for more information.

It sounds like you don't have the Vansco system, which means that you should have an Echo charger. There many posts on problems with the Echo charger, do a search.

If your's has the Echo Charger instead of the Vansco, it usually is a bad fuse near the battery. A "FIND" will show several redundant threads.
