Aux Batt Switch Problem

Hardy · 10-06-2013, 10:46 AM

On our 2006 Meridian The AUX BATT switch still rocks back and forth, and we hear the solenoid click, but there is no longer a beep and it is not working, as it does not shut the battery power off. We always turn it off when we store for more than a couple of weeks. We have been on the road for 3+months, so haven't used the AUX BATT switch since June, and it's now October. Any suggestions? If we have to replace the solenoid, what do we order and from where?

This is not the Aux Start, it's the AUX BATT that we normally shut down when we store the RV to avoid the drain from the monitors. We have used the switch with no problem since we bought the coach new, until now.

Any suggestions?

That is a electrically operated latching relay. Since it latches it does not draw current when at rest. Unlike the AUX start relay I haven't heard of many failures of this solenoid. I would call Lichtsinn Motors , a dealer close to the factory and get a new one from them.
If you want to trouble shoot it this diagram I drew may be helpful.
Note that the relay mode is switched by reversing the polarity on the two signal terminals - LG andLH.

Sounds like a failed solenoid. They may still click but not do the job.

Locate the latching relay. They usually have a 5A fuse right at the relay. If it is clicking it probably is not the fuse. But you need to find the relay to troubleshoot it anyway. Check voltage on both large terminals. Should be battery voltage on one and convertor voltage on the other when open. The voltages will be the same when closed. You might try cycling it a few times if it is stuck closed. This is a common relay. Yours might look different.

On our previous 03 Adventurer I replaced ours twice, first was with

second time was

I had to add a ground wire, because the cases were not grounded ( I think on both).

Kinda looks like the pictures failed to upload. Want to try again?
