Hello! So I have a 2000 XCSP that kept blowing headlight bulbs so I replaced the voltage regulator with an aftermarket one. After cleaning up the ground and installing it I started it (no electric start) and now have no dash lights along with no headlights. I just wanted to go for a night ride so I put the old one back on and figured I'd just replace a bulb if need be however the dash/headlights never came back on again! Both regulators light up so I know they are operational (only one yellow wire) and the brown wires (ground) have been cleaned up and is secured up against the chassis... I didn't change or do anything else so why wouldn't the old VR light up the sled? Any ideas??
