hi in this video I have a Suzuki with a faulty horn.
I am checking at the relay, this let me know that the horn switch in the steering wheel all the way to the relay is ok, then I checked that I had power to the load side of the relay and I checked for a ground (through the horn) on the load out put pin.
using the power probe at the relay plug, I could power up the horn and it didn't work.
a fairly short video showing how to test at the relay.
thanks for watching
