If my understanding is correct the turn signals should get no power at all if the relay is unplugged. Certainly there is no connection between the turn signals and brake lights. It sounds like your new harness has a short in it (power on ground), or possibly a bad diode. Do you have a manual or wiring diagram? I'll look at one tonight and see if I can give you a hand with a testing methodology. Sent via BlackBerry by AT&T

I have a 1992 Nighthawk 750 that ive slowly been putting together after Sandy. Its been a long process, and Im so close to the end, but Im stumped. My brake lights do not work (however the tail lights do) and my turn signals are always on. When I try to use the turn signal switch, it brightens one side and part of the tail light. The turn signals and brake lights function the same with or without the turn signal relay plugged in. The brake lights will not come on at all. The bulbs are fine. I checked and adjusted the switches for the brake lights, both work properly when tested with an ohm meter. My headlight works properly. My horn, starter switch, and engine off/run switch all work fine. Ive replaced many things on the bike so far, including: the entire wiring harness, the turn signal switch assembly, the turn signal relay, starter relay, the regulator/rectifier, and all fuses. When I check the grounds on the brake light I get a very faint positive reading, maybe .2v or less. Im pretty stumped here. If anyone has any input Id appreciate it. Perhaps a ground somewhere? Does anyone know if there are any near the lights I could check? Could the ignition control module cause this? I didnt replace it but the bike runs fine after Ive rebuilt the carbs. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
