My M3W has decided to have an electrical gremlin. The running lights and dash lights seem to be throttle dependent and flicker non stop when throttle is applied, the more it rattles the more it flickers. I'm safely assuming there's a loose wire, but I'll be darned if I can find it and don't know where to look. I've been through the fuse box and made sure everything is snug, but have not been able to source the problem. Any help is appreciated.

I would start with checking the battery voltage when running. See if it varies with RPM.

As for wiring, check the main grounding points for the battery (back of battery tray) as well as those in front of the oil tank. The back of battery tray grounding via a recessed head screw is a really poor decision on the part of MMC, IMHO. They really should have provided a welded to chassis stud for this purpose. One should probably remove the screw and clean the contact points annually to prevent issues.

I agree, often it is the grounding that is the cause of such gremlins. Never hurts to clean all connections as well.
