Coach battery drains after 3-4 days

[Tinman]

Hello I have a 2004 Roadtrek 190 Versatile that we purchased a year ago. The coach battery is not holding its charge and after 3-4 days it is drawn down. I changed the battery however that did not fix the problem. It looks like something is still drawing power even when it is turned off. Any ideas ? We love the unit and put 20,000 kilometres on it.

Coach battery not the chassis battery right? First thing I'd check is to make sure the Tripp Lite inverter/charger is set to "charge only" when you are not using the inverter. Roadtrek started using that inverter in 2004 so I am assuming your RT has it.

This topic: http://www.classbforum.com/phpBB2/vi....php?f=12&t=20 shows how to make a remote switch for that inverter.

The second thing I'd check is to make sure no lights were accidentally left on in the "trunk" or in a storage compartment.

All good suggestions, and I would add that you should check the isolator between the coach and starting batteries. They can also develop current leaks.

There's some isolator troubleshooting info in this PDF file from Hehr http://www.hehrintl.com/pdf/delcoisoman.PDF
I think it would apply even if your alternator is different. The '04 Roadtrek I owned had a Hehr isolator.

As a temporary fix, you can put a battery disconnect on the positive terminal. This will disconnect everything including the propane alarm and possibly the CO alarm, so having a secondary, battery powered CO detector is wise.
