Generator charging batteries question

So while in storage if I start the generator every two weeks to keep the charge on the house batteries, will it charge the engine starting batteries as well? Or do I need to start the engine to keep those two charged? I rather not start the diesel up. I just want to make sure I don't have dead starting batteries.

Removing any of them from the MH isn't going to be considered.

2013 Fleetwood Expedition 40x

Thanks!
  • You might find this thread interesting, as I had some great replies to the same question.

  • ALL Fleetwood coaches are designed to charge the chassis and house batteries from the converter or Inverter/Charger when on shore power or the generator is running.

    If yours does not, then you have a circuit, or solenoid, failure in the BCC.

    Yup. Pretty much.

    Buy an inexpensive multimeter and learn how to use it.

    For starters; There will be several scales to choose from, volts, both AC and DC, Current (Amps) and Resistance (Ohms or ? )and possibly others. For the battery you will need DC Volts which may say that or just show a dashed line - - - - with a solid line over it. You will also need to select the voltage range, which may be 10, 50 100 etc. Chose 20 if that is an option or the next one higher. The red lead goes to positive and the black to negative, though on a digital meter it won't really matter, if you happen to reverse them it will just read - (minus).

    Hi,

    Most will not--but some do. Take along a volt meter. Measure the starting battery voltage. Start the genny, then measure again. If the voltage went up tha answer is yes. If it did not, then add either a trik-l-start or an amp-l-start unit.
