My horn recently failed, so I've purchased 2 Fiamms (one high & one low). I've been looking online for instructions and have found numerous posts about using a relay, so I got a relay: Bosch 0-332-209-158.
Here's what I'm encountering:
1. Connect 1 horn to the existing wiring - nothing
2. Connect 1 horn to just the hot wire and ground to frame - BEEP (without pushing Horn button)
3. Connect both horns through relay: hot on 86+, ground on 85, 12v from battery with 20 amp fuse on 30, connect both horns to 87a - BEEP (without pushing Horn button
4. Connect both horns the same as #3 but instead of 87a for the connection to the horns, I connected them to 87 - nothing
What is going on here? I have continuity at the hot wire at the output from the horn and at the horn switch, nothing seems to be shorting out.
Any ideas... ??
