Is there any mechanic any salesman/woman on here that has dealt with Holiday Rambler in the 80s? I am not trying to be a pain, but I see 5 replies to this and they are mine.I was hoping that someone would jump in and let me know. What circuits does this thing power? I can't find any info in the motorhome manual (which sucks ) and all I got with the Honeywell is a warranty card. I know that it senses load so there is no switch to turn it on. but what circuits would this power? It is wired into the motorhome. Please anyone have experience with this setup? I am sure it was an option HR offered. Thanks again.
