Model #: 005882-0 Serial 6047890
Propane or Natural Gas: NG
Length of gas pipe feeding the generator: 16 feet
Size of gas pipe feeding the generator: 1 inch
How long since the last full maintenance: July 2019
How long have you experienced this problem: 1 day
Unit installed January 2011
My Genmon monitor sent me a text this morning, "Check Battery". I looked at the battery voltage and it was down to 12.3 volts. Normally I never see it below 12.6.
Checked all battery connections at generator, very tight on the posts.
Checked T1 voltage at the connection block at generator, got 120V.
In January 2020 I replaced both battery cables and battery. It started fine for exercise last Saturday.
Hooked up my voltmeter to test the amperage going through the system by unhooking the negative cable from the battery and placing voltmeter in series. With 7.5 amp fuse plugged into the top of the controller, reading was .275 DC amps. Removed 7.5V amp use, went to zero. Plugged fuse back in, reading .275. So does not appear to be charging.
I unpowered everything from the generator. Battery, N1/N2/T1 fuses from transfer switch. Unplugged the connectors from the bottom of the controller thinking I may have a wiring problem somewhere.
I checked continuity from the pin in the connector where T1 is located with the wiring block where T1 comes from the transfer panel. Good continuity.
I checked wire 13 from the other connector to the post on the starter contactor where it hooks up to feed the positive battery cable. Good continuity there.
I looked at the pins in the connectors, none appear to be "pushed back" so they wouldn't make contact with the controller. Pins in the controller are tight and don't wobble.
Before I go any further I'm hoping one of you folks might have some additional steps I can take next to see if I can solve this once and for all.
Thanks in advance for your help. Below is a link to the post I made last year with this same problem, and a photo of the controller.
