I'm wiring up my HID ballast and bixenon projector. To move the bulb shield and switch from low to high, I need to apply 12V/or ground to a relay.
The bixenon projector has 4 wires to it that control the bulb/sheild. 2 apply power to the HID ballast and light the bulb. These need to go to a switched source and come on when I turn the key on. I'd like to keep this to a constant hot lead at all time, as killing the light to turn the starter isn't going to be good for the HID bulb or ballast. Ideally I will switch over to a euro headlight switch and can turn the light off before starting the bike/turning on the key. Of course, those are 150+ on ebay, and I'd rather not drop the coin on that at the moment. Not sure what to do here.
The other 2 wires are to move the shield, but applying 12v to a solenoid.
I've found the headlight relay on my monster. It has 4 wires going to it. 2 are constant hot all times, one ground comes on when you turn the key, other ground comes on when you switch on the high beams.... I figure I can wire in the shield solenoid to the switched ground on high beam and a constant power? Or will that somehow hurt it?
why not get a small 12v switch from radio shack and mount it somewhere before the ballast.
I can do that for the light to avoid the turn on/off when I start it [thumbsup] I suppose
just make sure you put a fuse in line with it.
