2010 600 IQ been at the dealer about two weeks. I brought it back to them after a 185 miles on it, it developed the volt meter drop, then flashing at one bar. Any touch of the brake or switches the Instrument panel would blank and tach would drop off. No head/tail lights either. Sled idled and ran same as always, ripping. But they(dealer) can not duplicate this after several trial runs. Suggestions, I've been fishing around for a cause but nothing jumps out, it could a number of things.
