If you have to open AND close the disconnect it seems to me like the switch is bad. Opening and closing it again wipes the contacts and makes it work again temporarily.
I have a "key" type disconnect switch. I guess I'll spray it with wd-40, let it sit a few days then force some dielectric grease down into it. Any other cleaning idea vs replacement?
I might add, I added this disconnect when I had the trailer sitting for an extended period of time and the batteries would drain. I placed the switch in the negative leg just after the battery terminal which is the - leg that goes to the converter. As we now live full time in the TT, I never open the switch, except now, when the 110v power fails and I need to go turn the switch on and off to get the batteries to kick in the 12v.
Good or bad?
