I have a 2014 Winnebago sightseer. During the summer I have it parked at my cabin and plugged into 50amp shore power 24x7. After being gone for a couple weeks, I came back up and my chassis battery level basically drained(It's less than a year old). I know that if I store it, I need to switch the coach and chassis batteries off. But I thought as long as I was plugged into shore power, the chassis should keep a charge. The coach battery is normal. I was hoping to start the unit using the battery boost switch and charge the chassis battery, but that wouldn't work either. SUGGESTIONS appreciated....

THANKS

The manual doesn't mention that the chassis battery would be charged from the converter.

Well, I looked at the charger you recommended. Seems to me that you could purchase a less expensive one at any parts store. Or, just run a wire from the positive post of the house battery to the positive post on the chassis battery and let your house battery charger recharge both.

Running a wire between the batteries also means that house loads when not on shore power will depelete the chassis battery, which undoes one of the primary reasons for having two batteries. Having one with a switch (and appropriate current limiting/overcurrent protection) would be okay if you always remembered to operate the switch properly.

The battery tenders/trickle chargers you get at parts stores are different in that they are AC powered rather than DC, and I think at least some tend to discharge the battery if they are connected to the battery but not to AC power. The really nice thing about the Trik-L-Start, besides being a reliable, well-built device, is that it always just works without needing any additional effort on your part. It also has the advantage of working properly if the house battery is being charged by solar rather than by shore power, under which conditions a plug-in battery tender would not be so useful.

Yes that is correct.

The Trik-L-Start combines and separates the batteries automatically in all conditions with any charging source to the house battery including generator or solar.

The wire does not and needs a fuse unless sized the same as largest existing connection. Put this on your list to connect or disconnect as needed.

The separate on board maintenance charger could be plugged into the RV 120v system to always charge when plugged in. Otherwise add it to your list to plug in as needed.

You got it backwards
The converter charges the COACH battery.. now on a 2014 it should alo charge the CHASSIS but.. with the coach batteries off. it might not.

Your voltmeter is your friend. Use it to measure voltage AT THE BATTERY TERMINALS

After 2 hours without charging 12.x is good. the .x determines the state of charge (Without double checking I think .6 is full)

With the converter connected and charging 13.x is common.. NOTE depending on your converter it may go up and down so try mulitple readings over say a 30 minute period...

Also. WHAT is the converter model. in some Rigs this is the power center model In others. the converter is a in a different place (Mine is)


Home is where I park it.

Disconnect Switch

My coach doesn't charge the engine battery either.

A simple disconnect switch will cure the problem.

My coach already came with a built in engine disconnect switch but that one, or a similar one with different post connectors, will do the trick.
