I have a 2003 MXZ 500 that runs great. This past weekend when operating everything works fine until I pinch the throttle. Once the RPM get up to 6-7 K, the speedo and tach drop to zero. Once I let up, then the tach starts working again. One other thing to note, the headlight operates all the time.

I thought there may be short somewhere but believe I have checked all the wiring.

Looking for help.

Thanks
