Salesman 12V solenoid

[f365gt4]

Can someone identify the small silver solenoid in the lower right section of the photo. This is in the engine compartment, passenger side, power box. I think it’s the salesman switch solenoid used to disable 12v. I need to verify this is the guy that drops the 12v in a 03 Dynasty 38'.
Thanks

looks right to me. that's pretty close to the same arrangement in my 99 exec. IIRC has a purple wire landed on it from the switch. ST85 at NAPA.

You mean the one marked " Batt. Cutoff ", the actual name for it ?

Yup, that's it.

Don't think do. From what I can see the blue box is a diode battery isolator that allows charge current to go to two batteries without any backflow. The solenoid appears to connect the two banks around the diodes...bet it is your boost start switch...

Red circle = Battery isolator

Green circle = Boost Start Solenoid.

Yellow circle= Lambert chassis battery maintainer.

Blue solenoid = Battery Disconnect.

Sorry. reading comprehension suffers as we age. Didn't see the reference to the "lower right" Twinboat is right...as usual. If you look closely the lower right solenoid is actually labelled "cutoff."

All that good information is now in my notes, thanks. I bought this RV two years ago and my first problem was loss of 12v. I moved the wire on the right to combine it with the left and marked the solenoid. Two years later I couldn’t verify that I did it correctly and it was just something that was annoying me. I knew one or more of you would know. I ordered another solenoid at the time but it didn’t look like that one so I never put it on.

I like how twinboat identified components, great job.

he just taught me a new trick., tks. I almost bought this 2 yrs ago but it was too long.

You guys should always listen to and never question twinboat!
That guy is by far one of the most knowledgeable electrical experts here!
Especially on the "how do I wire my 30 or 50 amp RV outlets" threads that most other responders are way off on.

This coming from a retired master licensed electrician!

Twinboat has been right since God was a corporal.

Just replaced the battery cutoff solenoids on our Signature, here is the post including wiring diagram and where we purchased the OE replacement:

The OE part for our battery cutoff solenoid is a White Rodgers 70-111224 80A Continuous Duty solenoid. There are many other options to choose from as well.

All the best,
Josh

I just received the daily newsletter and saw where Twinboat went on a little rant about using the term salesman switch. That term was what I picked up from reading site blogs and I figure he’s probably 60% right, it’s funny. Not a big deal, he quickly shared the right information to my question and then some. I haven’t had the big coach very long but I’ve made some big changes and still working things out with the help of the web. This site especially. Since 04 I ran a much modified 99 Dodge dually, lance, and trailer (63’) coast to coast and up and down several times to get my feet wet. The fun was there but it lacked comfort. I have the comfort here but bigger problems, I’m still a little leery of taking the trailer.
JJTL thks for the solenoid info

My eyes cannot discern what the device is just above the blue circled solenoid. Is that a latching relay??
