Battery Isolator Problem


We have a failed Battery Isolator. Our local mechanic shop is not having success with finding a new one. Any thoughts?

Also, any sources for troubleshooting the battery isolator?

Which one? Back of battery tray or engine compartment. What MH are you running?

Victron makes isolators as well.

They are a pretty standard item in a variety of motor homes. Finding the exact part used back in 1979 .... not so much. There will be a little bit of adapting to do with whatever you decide to go with.
