Question about something in the Coach Battery Box
Newbie Class C motorhome owner. Opened up the battery box. I don't recognize the electrical device I have circled in red. Can someone help tell me what this is? Thank you!

It is one of 2 things OR the same thing.
1. It is the battery disconnect solenoid(not likely due to the 2 large battery cables)
2. It is the Solenoid that closes to charge BOTH chassis and coach battery banks (99% correct)
3. It is the SAME solenoid that is the emergency start AND the dual charge solenoid. A LOT of Motorhomes use the same solenoid for this purpose. The BAD news is, IF it IS a Emergency start solenoid, it is not HEAVY(Large) enough for that job. THAT solenoid is rated at no more than 100 amps draw thru it. It probably does the job, but an emergency start solenoid really needs to be either a 150 or 200 amp rated solenoid, but few older motorhome makers put those in.
4. The fact that you have 2 large heavy battery cables point to a emergency start solenoid that probably does double duty as a charge solenoid also. Doug
