jking2000 Report post Posted May 10, 2012 I just replaced all four 6V batteries because the originals died (my bad). Now, I tested all the 12v systems and only the awning would not work. I looked and the Inverter/charger was not on charge. Now I do have a 50Amp Motorhome plugged into a 30Amp thru an Adapter. The Voltage of the batteries show 12.8V in the Inverter controller. But I noticed once I start the generator the Charger goes into Bulk Charging mode and after a few minutes the awning comes out. My question, is the charger not suppose to work on Shore Power also, or is it because I am connected to a 30Amp Power Source. This would explain why leaving the Inverter on by accident would drain the batteries, even though I am connected to Electric. James King Share this post Link to post Share on other sites
wolfe10 Report post Posted May 10, 2012 James, Yes, if properly wired, your inverter/charger should work just fine on 30 amps. If you have a digital voltmeter AND ARE SAFE WORKING AROUND 120 VAC, check the following on the 50 amp female side of your 30 amp male to 50 amp female adapter: Either outer straight (hot) to center straight (neutral)= 120 VAC Either outer straight (hot) to center round (ground)= 120 VAC Center straight (neutral) to center round= 0 VAC If reading are different, UNPLUG and let us know what your readings are. You could have a problem in the adapter, or with shore power, or in the coach-- but, let's start by verifying that your 50 amp female end of the adapter is supplying the proper power to your 50 amp shore power cord.

jking2000 Report post Posted May 11, 2012 Brett, Thanks for the suggestions. I am not real comfortable working with 120VAC. But reading your Instructions led me to one simple solution. I have a brand new adapter as a spare, so changed it out POW it is charging! So guess I need to replace the spare with a new spare. Thank You Share this post Link to post Share on other sites
dickandlois Report post Posted May 11, 2012 Sweet, When I carry spare parts, never seem to need them. But if I leave them home-- that is when something will fail !!! Rich. Share this post Link to post Share on other sites
