Meter should read voltage either positive 12 volts DC or negative, then have helper hold in other position. Meter should read 12 volts DC with opposite polarity. After the switch is removed there will be the two small terminals you mentioned. That will tell me I should be getting 12 volts DC both ways? Positive and Negative. Good idea ... I'll see what I can do by myself. Thanks for sharing.Re: Battery Disconnect Switch ?? bobndot wrote: Make sure the connections on the relay solenoid are clean. The solenoids are not expensive, i would buy a new one and try it. Its a common enough fix in these systems, if that doesn't help, keep it as a spare. Its a good part to have on hand. I'm presuming that the relay solenoid, you mentioned, is located in the battery compartment under the step to the right with the cable connections. Had a SC moment ... Maybe this might help, and I should of mentioned this before but with the generator running the battery connect switch will activate. However the DC/Coach power does not activate otherwise. Will check this out further ... Thanks for the suggestion.Re: Battery Disconnect Switch ?? enblethen wrote: Pull switch from the wall, check for 12 volts DC No power, check for blown fuse. Cycling is operating from one function to the other and back. Like you did. Checked all the fuses that power the coach and all are good.Re: Battery Disconnect Switch ?? enblethen wrote: Battery connected corectly< polarity?
