No offense intended--are you sure it's in neutral?

Thanks DM

Everything appears as it should except no elec seems to be getting to the panel nor the engine from the main cables.

Blown fuse on engine is the most common problem. Have run voltage test to see where loosing voltage.

Thanks,

We have checked all the fuses and they appear OK. I have heard that Yahmaha is having problems with battery cables on newer engines. That will be next with a line tester. Thanks everyone.
