I thought of adding an inline switch, that was the idea I was thinking might be the easiest option. As for the batteries being bad, nope they are good they did not get drained right away, it's been several days since they were installed. I assumed these ran off the house battery as well but if the house battery drains does it start to use the main battery that starts the engine? Also there is not a stock battery cut off switch, I would have to add one but was not sure at which battery to add one too. I assumed if a battery would be drained from the detectors it would be the house battery, but it seems its the main battery to the engine as I can't start the MH. Keep in mind he old detectors had on and off switches that I manually turned on when using the MH, and turned off when not using the MH and that way the batteries were not drained. When I first bought the MH I did not know you had to turn off the detectors and the same thing happened the batteries drained. Since then the batteries have been fine until I swapped the detectors and realized they had no on be off ditch and after several days running they drained the batteries. If I were to put a battery cut off should I do it at the house battery only or both?
