Have 04 big dog chopper that quits, lights out, speedo out, after on the road for 10 miles. The key seems to be dead however, the relay by the battery clicks like it should, however no lights on EHC. Let it sit a few minutes, turn key back on and everything fires up, go another 2 miles and lights out again. Replaced relay, bike started up long enough to load in trailer, unloaded bike and it won't power up at all. Is this ultimately a faulty EHC that I have been reading about, and can you get new one from Big Dog.
