ktconners Report post Posted July 1, 2019 If you are parked at a campground and plugged into shore power for an extended period of time (over a month), is it necessary to start your Class A to charge the battery? I am not clear on this and would hate to have departure date arrive, only to find the vehicle will not start... Thank You! Share this post Link to post Share on other sites
wolfe10 Report post Posted July 1, 2019 Not a simple answer. Yes, your house battery bank should remain charged by your converter or inverter/charger. But, not all coaches have a means of charging their chassis battery from shore power. Safest answer is, after a couple of days, check voltage at both battery banks with a digital voltmeter. That will give you the FACTS for your coach. And, if the chassis battery is not being charged, there are several common remedies that do include running the main engine.

ktconners Report post Posted July 1, 2019 Thanks Wolfe. Sounds like the safest thing us just start the engine, now and then. Appreciate the reply! Share this post Link to post Share on other sites
wolfe10 Report post Posted July 1, 2019 That would be well down my list of how to address this. Running any engine under no load allows moisture build up in the crankcase. That in addition to using a lot of fuel to turn a lot more cylinders than are needed to spin the alternator. If you don't have a digital voltmeter, a good idea to get one. They start under $20.

wildebill308 Report post Posted July 1, 2019 Like Brett said "first find out if your batteries are being charged." If they are you are done. If they are not being charged let us know and we can offer a simple fix. Where are you now? Is the coach plugged in? Bill Share this post Link to post Share on other sites
ktconners Report post Posted July 1, 2019 Yes it has been for about a month and a half. My readout says “chassis battery voltage 13.1 v” and “house battery voltage 13.1v” Share this post Link to post Share on other sites
wolfe10 Report post Posted July 1, 2019 Looks like you are covered. But, since we don't know what coach and/or converter or inverter/charger you have, be aware that if it is an inverter/charger, it is programmable. If you have an inverter/charger, let us know what you have and we can help you to "fine tune" it for your batteries. Share this post Link to post Share on other sites
ktconners Report post Posted July 1, 2019 I just looked again now it says chassis bat voltage 13.2... Share this post Link to post Share on other sites

ktconners Report post Posted July 1, 2019 I have a 2017 Fleetwood Bounder 36H. I know it does have an inverter but no idea what kind. On my control panel there is a box that says “Magnum Energy”. It reads out my voltage, 13.1, followed by “float” not sure if that is the inverter or not? Sounds like I am OK for now though and appreciate your help...

wolfe10 Report post Posted July 1, 2019 With a new coach, you should have an owner's manual for your Magnum inverter/charger. It will give the (easy) steps for programming the inverter/charger. If no manual, go to Magnum's website where you will find an on-line manual. Do NOT ASSUME that it was properly programmed at the factory. You could also call Fleetwood with your VIN and they can tell you exactly what inverter/charger you have. Share this post Link to post Share on other sites

Now, if you have the owners manual and can fill in the model of magnum you have that way we can help fill in the gaps a little for you. Magnum Power is the most common name I know your equipment by.
