I was recently gifted a 2007 Yamaha Grizzly 660 from my brother. The bike is in great shape, but is having electrical issues. Good battery, brand new meter, but no power coming from battery to the ignition switch and meter. I have checked all fuses and they are good. Wiring harness is good also. I’m thinking maybe the CDI box is bad.

Has anyone here had the same issues? I’m stumped.

If it has a Warn winch on it the CPU may be fried

It does. It was working up until a few days ago when I heard a click coming from what I’m assuming is one of the relays.

Those warn winches had the bright idea to tap into a power wire that runs to the cdi. Trace your wires back. Remove it. Clean it. Liquid tape it.

Pray.

It was a terrible idea.
