Re: Battery solenoid isolator
I can actuate the solenoid manually with a battery charger applying power to the small side post terminal. The solenoid will click and if the engine is running, the alternator current flows to the battery. The oem wire coming from the fire wall to the side post terminal has no power, even if the engine has been running for a half hour...I’m thinking that it may be wired into the ignition switch since none of the fuses are bad at the fuse box, but if that’s the case how come I don’t have any other issues...

Re: Battery solenoid isolator
Thanks for the replies, I like that Sure Power battery separator. I'll have to pull the instrument cluster and trace the solenoid power wire back to its origin. If I can’t find the source, then I'll run a new power wire from the fuse box.

Battery solenoid isolator
I have a 1979 Monaco with the Ford E-350 chassis. The secondary battery for the coach doesn’t get charged while the engine is running. Does anyone know where the power comes from to energize the solenoid that allows the alternator current to the battery? There isn’t a transfer switch inside the cab to energize the solenoid. I checked all the fuses, they are good. I can manually energize the solenoid with a battery charger and it clicks as advertised. Any help would greatly be appreciated.
