Re: 30 ft sierra battery wont work

Make sure your battery disconect is on if you have one. Make sure the battery is good. One thing I had happen a few years ago. The battery charger converter, it has to switch back to 12v. There is a switch in there and the older ones stick. If you tap the converter and it starts working that is it. You can replace that old style switch with a new one that is solid state and it won't happen again.
Good luck
