2023年8月3日 · The horn relay is triggered by ground. One tab at the steering wheel horn button should be ground constant. The other is a signal return to the relay trigger (small black wire at the horn relay). If you’re seeing 12v and ground at the steering wheel Horn button something is wrong as that would cause a short. Also, you’re concern at the horn ...

2020年6月2日 · Question, What is the black box beside the horn relay? I had a problem with my radio, and a few lights stayed on after I had turned the ignition switch off. I thought that part of the ignition switch was bad since my aftermarket voltage gauge worked like normal. But when I unplugged that box the problem went away.

2007年10月25日 · I am restoring a '70 and put a tilt column out of a Pontiac in. All was good until the horn a blinkers quit working. I replaced the blinker switch and that got the blinkers working but the horn is a different story. I had the horn working properly for about 10 minutes.

2016年12月17日 · (heater relay, voltage regulator, power top switch) The green wires send power to the horns. The solid black wire is going to the horn button (the horn button sends a ground through it to energize the relay) Those four wires in the background behind the relay in that picture look like they might be to the voltage regulator. ???

2020年7月25日 · The relay bracket is just to have a way of mounting the relay and not have it dangling by the wires attached to it and possibly have terminals short to ground on the exposed connections from the battery. Now this ONLY applies to an original and properly working horn relay/key buzzer.

2000年7月21日 · Having no horn relay has nothing to do with the charging system. Also you should never pull the pos battery cable from the battery with the car running, it can blow the diodes in the alternator. To see if the charging system is working, check the voltage at the battery with the car running at a fast idle, should be between 14-14.5 volts.

2004年4月1日 · DO I need the horn relay on a 69 chevelle. I am trying to clean up a car that someone stripped the AC out of and changed the Alt. so I am trying to clean up some wires.
