Battery disconnect solenoid

[Tom_Barb]

I wonder where Newmar hid this thing in 2000
Have a battery system that was disconnected and now will not connect again. I'd like to see if it is getting voltage when the button is pushed.
anyone know where Newmar put these in 2000 Mountain Aire?

Nope, thats the isolator relay that separates the chassis battery from the coach battery pack. and allows the main engines alternator to charge the coach batteries when driving, and the shore cord to charge the chassis battery when plugged in. It is controlled by the Bi-directonal Isolator relay, right next to it.
There is another relay there but it is not the same type. it is to connect the coach batteries to the chassis battery for a boosted start.

Its there. You are just NOT seeing it. Have you removed the black plastic flat velcroed cover that hides it? Doug

You were absolutely correct.
removed the 4/0 cable rom the coach batteries ground terminal placed it on a positive terminal.

It's a wonderful thing how well things work when connected correctly..
The coach is fixed.

the latching relay in the power cable compartment really is the battery disconnect. that is when you hook it up correctly..

This all started when I removed all the batteries or a fuse replacement.

My cover is clear, and it is removed there is two relays there. 1 is for boosted start. the other is for separation of the 2 battery packs.
1 is a latching relay, that the right side 4/0 Cable goes directly to the chassis batteries (+). the right side is a short 4/0 cable the goes to the boosted start relay that is not a continuous use relay. the boosted start relay's other post goes directly to the Couch battery (+)

coming from the coach battery pack there are 3 other 4/0 cables that go forward from battery compartment and disappear forward in to the interior of the coach.

but your right, I'm missing something. the solenoid that separates the coach battery pack from the coach 12vdc distribution buss.
there are two 4/0 cables that go from the coach battery pack, 1 a (+) and 1 a (-) that go directly to the inverter. there is 13.8 volts present at the inverter between the two. the inverter will not turn on. because there is no control voltage at the control panel.
Plug the coach's 50 amp cord in to the house and you get a fault on the inverter control panel that says no battery voltage (dead battery) simply because the battery shut off solenoid is open.
un plug the 50 amp cord, start the gel-set, same thing occurs.

Look near the frame rail by the batteries. May be by the inverter.
Do you have a small compartment under the driver's seat by the front wheel. some diesels have fuses and controls there. But the relay should be close to the batteries.

Our battery compartment is the last one back on the right side, outboard of the engine. the inverter / charger compartment is just forward of them behind the wheel.

In the AM I'll make the crawl under to see if there is any thing on the frame between them.

YES,, Intellitec ... PN 01-00066-001

I've found the service Manual

I think it has a blown fuse on the solenoid, just have to find it and look.

See my edit after I saw my mistake.

Our's is a diesel pusher, the firewall is big box under the bed.
Our's won't click.

[STBRetired]

On my 1999 it is in a box mounted on the firewall. Open the hood and look to the upper right.

Edit: Just noticed that your MH is the DP not the Gasser. I had an issue with my disconnect switch where I had to hit the switch 3 or 4 times before it would reconnect. Ended up replacing the solenoid. Won't help you find the solenoid, but might get you 12V power for the short term.

For the long term, check out Newgle (link). You register your MH serial and it gives you access to any documentation that Newmar still has for your MH. Bad part is, it takes like 3 days for Newmar to send you your login.

Can't help with your brand, but my disconnect switch is on a side panel near the entry door, and I can hear the solenoid click someplace very close to the switch. I think it's in the box just behind the switch. But now that I see you asking this question, next time I'm at the motorhome I'll listen closer and make sure I know where it is, just in case it goes out.
