Inertconnect solennoid for chassis battery

Yesterday all was fine except my chassis has 10-11 volts and needed replacing. I buy a new battery Optima red and now the chassis disconnect switch is off and won't toggle on. I put the ohm meter to each side of the solennoid and it read 0. the fuses, on the solennoid are 5 amp and are ok. I realized I have two of these soennoids and I don't know how to proceed. The electrical is a bit out of my knowledge zone. Can it be that the toggle switch is bad and not the solennoids. And how do I check to see if one or both are bad. btw this is an 08 winnebago voyage 32h w/workhorse chassis Also is it ok to drive in this condition. I had to toggle the battery boost to turn on the engine. Thanks from John at Whiskeytown Lake just west of Redding, Calif.

Did you try installing a jumper across the toggle switch or ohm it out to see if its bad? If you drive without the chassis battery connected, the engine computer might not like it.

You may want to check to see if the battery is discharged. I would check that and charge it if necessary. If it is dead the RV might not be able to charge the battery.

Thanks for the replys. The battery is Brand New optima so I know that's not the problem. I did not try the ohm meter test on the toggle switch either. Well lo and behold the light came on in the toggle switch. I drove nearly 200 miles today and at the end of the day I turned off the engine and when I restarted I did not need the engine boost swich on the dash. Well that doesn't solve the problem of the toggle switch acivating the solennoid to disengage the chassis power. I need some brain storming. Help!!

What is the manufacturer name on your "Battery Control Center" (BCC). On Gasser RV's it is usually under the hood but on diesel RVs it can be somewhere in the back of the RV.
I know a company called "Custom RV Products" manufactures many of them for RV's. If it is Custom RV Products you can contact them and they can email you a schematic and troubleshooting information.

They helped me with my chassis disconnect. I jumpered my chassis disconnect relay out and do not plan to replace it. Here is my post.

mgscott4--I'll look at it tomorrow and see. I read the link you provided and will look at my rig to see what matches. I made a copy. I don't know the manufacturer of the BCC. I'll crawl around in the light of the day and get back to you. Thanks, John
