[QUOTE="Fred W, post: 534533, member: 3828"] Knucklehead, I have the HID headlights set up the same as you, with its relay box driven off of one of the two headlight connectors, so that the HIDs don't fire until after the engine starts. And I have experienced the "one headlight" symptom occasionally as well. What I've noticed is that this seems to happen on the first start of the day when the battery hasn't been on the tender, especially if I have left my Hella FF50's and / or heated grips on. I don't think it has happened since I began being sure to turn everything of when parking. My guess is that the battery voltage gets drawn down by the starter and the headlights try to fire-up immediately after the engine starts, the voltage hasn't yet recovered. What would be ideal would be a few seconds of time delay added to let the alternator come up to speed before attempting to fire the HIDs. Your momentary "switchus interruptus" idea would work OK too. But the place you want to add the switch is in the control signal to the relay (where it comes from the headlight socket), not the high current main wires running from the battery +. You did run those heavy wires directly from the battery, right? [/QUOTE]
