I have a 2008 Diplomat & after changing the 4 house batteries.
I noticed that the relay from the battery cutout switch was hot. This is a Trombetta 12 volt solenoid or relay located in the battery compartment.
By hot I mean the brass bracket that wraps around the solenoid to hold it in place is so hot that if you put your finger on the bracket for more than 2 seconds, it will burn. If you only touch the solenoid itself, it's warm. I just replaced it with a new one & it is just as hot as the old one.
Can someone out there physically go out & touch your bracket & solenoid to see if it is hot as well ? We have been parked on a site in Florida for the past 4 months so the batteries are on flow charging.
Thanks for any help.
