ShellysRV Report post Posted September 28, 2015 Have sent Inverter off to have it looked at. So far they have not found a issue with it. It is not recognizing when it is plugged into shore power, so it draws the batteries down. Batteries on Chassis and House have all been replaced. If they don't find and issue with the Inverter, what might else it be. Share this post Link to post Share on other sites
wolfe10 Report post Posted September 28, 2015 ShellysRV, Welcome to the FMCA Forum. First step is to confirm that you do have 120 VAC to the inverter from the coach main 120 VAC breaker panel. Share this post Link to post Share on other sites
rossboyer Report post Posted September 28, 2015 There should be a 30 amp breaker in your shore power panel that feeds the inverter. Check to see that has not tripped. I would turn it off and back on. Also, are you sure that the shore power is getting into the power panel? You may have to take the cover off and check with a meter, but don't do it unless you are comfortable with diagnosing power panels. Share this post Link to post Share on other sites
geodaun Report post Posted September 29, 2015 Did you check the Transfer Switch? It may not be transferring power to the Inverter. George Share this post Link to post Share on other sites
wolfe10 Report post Posted September 29, 2015 George, Were the ATS (Automatic Transfer Switch) not functioning, other 120 VAC appliances would not work either. Said another way, if both roof A/C's work, you KNOW the ATS is functioning properly as that proves that both hots as well as neutral are functioning from shore power.

ShellysRV Report post Posted September 29, 2015 This is what they found with the Inverter: Found that a Fuse was blown, and the fan was not working. Both needing to be replaced. He also found when he opened it up that an insulator sheet was missing, which protects the Circuit board from metal. Hopefully this fixes it. It was not original to the RV and had been replaced but I am sure the previous owner didn't look into getting if fixed. Will keep advice above just in case. It was working fined on shore power at my home and when we traveled before we started having issues. Share this post Link to post Share on other sites
ShellysRV Report post Posted October 3, 2015 Ok. I guess I need to look into what you are all talking about above. Got the Inverter back hooked up a couple of days ago. I noticed tonight that the "bulk" was blinking red on left side of remote control panel and the fault was "red". So it is still not charging when plugged in. The left side was green and 30 amp (at top) on the share. Any suggestions. Frustrated, want to use it next weekend. Share this post Link to post Share on other sites
wolfe10 Report post Posted October 3, 2015 Use a digital voltmeter and check voltage the house battery bank. Many inverter/chargers will not charge if the battery voltage is extremely low. Let us know what you find. Share this post Link to post Share on other sites
ShellysRV Report post Posted October 4, 2015 I charged the batteries yesterday. I can hear the Invertor clicking , should it be doing that. Share this post Link to post Share on other sites
