Disconnecting the battery and re-connecting sounds like a good idea.

Completely separate problem for me recently was the light in my very expensive oven at home, it was going on and off like it was completely going nuts. There is no on and off switch so I killed the breaker to that circuit. Turned it back on and the problem went away.

I may be the only person that has re-booted their oven, like we sometimes have to do with our doggoned personal computers !
