i have a pair of 1990 artic cat snowmobiles and they keep burning out headlights and taillights someone said it is the external voltage regulators is that right thank you for any help . I put a volt meter on the wires of the headlights on the one and it read 2 volts is this normal .
I think you need an AC voltmeter to read that. Yes, it does sound like bad regulators or wiring. Measure the AC voltage right at the regulator. If it's high the reg's bad. If low or nothing, bad wiring.
