Speedymaru Posted October 12, 2017 Report Share Posted October 12, 2017 I'm wanting to get my horn working. Im not sure where to start. I did a little research and found that the relays go bad pretty often, but couldn't find anything 620 specific. I need to find out where the horn relay is. I already checked the fuse and it's good. Just not sure what to troubleshoot. Any advice is appreciated Quote Link to comment
Speedymaru Posted October 12, 2017 Author Report Share Posted October 12, 2017 Forgot to mention that I tested the horns and they both work Quote Link to comment
datzenmike Posted October 12, 2017 Report Share Posted October 12, 2017 On the right inner fender is a black plastic box that cobers all of the relays. Take it off and the horn relay is the one closestto the front of the vehicle.It should have a LightGreen a Green and a Green/White wire to it. Try the horn and see if it is clicking. Light green wire is grounded when the horn button is depressed. Green/White goes to the fuse box and should have 12 volts on it at all times Green wire goes to the horns. Quote Link to comment
Speedymaru Posted October 12, 2017 Author Report Share Posted October 12, 2017 Okay cool. I took the cover off, and I didn't hear a click when the horn was pushed. Does this mean the relay is bad? Quote Link to comment
datzenmike Posted October 12, 2017 Report Share Posted October 12, 2017 Try unplugging several times to clean the contacts Check for power on the Green/White wire. Ground the Light Green and see if this works the relay Quote Link to comment
Speedymaru Posted October 12, 2017 Author Report Share Posted October 12, 2017 Will try to clean the contacts soon. I checked for power and there is constant power. Do I ground the relay itself or the plug? Could I use a 9v battery and connect the positive to the constant tab, and the negative to the light green tab? Quote Link to comment
banzai510(hainz) Posted October 12, 2017 Report Share Posted October 12, 2017 it might need 12volt but I think 9 might trigger the relay and ohm out the contak side for a short 1 Quote Link to comment
datzenmike Posted October 13, 2017 Report Share Posted October 13, 2017 Try holding the horn on and give it a wrap with a wooden hammer handle. Quote Link to comment
Speedymaru Posted October 13, 2017 Author Report Share Posted October 13, 2017 I tapped it a little bit, and now the horn works. It does not sound good, so I'm going to be installing a new horn. In order to get the horn to work, you have to push on the inner part of the button, closest to the center of the wheel. Is there any way to adjust this? Quote Link to comment
datzenmike Posted October 13, 2017 Report Share Posted October 13, 2017 The contacts corrode like a dirty old copper penny. The best thing is to repeatedly tap the horn button. If the horn is annoying, disconnect them. By tapping the horn several dozen time you will polishing the contact areas. Allow the horn relay to click also to do the same thing. Quote Link to comment
