Wolo horn relay
« on: May 05, 2013, 04:44:24 am »
Ok, you're going to love this one.  I installed a Wolo air horn a few months ago.  I did not use the relay...why?  Cuz it was an easier install w/o it, and it worked fine.  Anyway, I have been reading from others, that the horn w/o the relay could cause the switch to burn out.  So, yesterday I decided to install the relay.  The schematic I had, listed #87 on the relay as an option...either connect it to the pos on the horn, or leave it off.  Everything worked great leaving it unconnected, but thought I would try option "B", and connect it.  Several minutes later, I noticed the bike was "turned on", although the key was in the off position!  I turned the key to on, started the bike, and then could not turn it off.  The key would not turn.  Since I still had the battery exposed, I disconnected the negative, and the bike could then be turned off.  Hmmm.  I then disconnected the #87 to the horn positive, and everything works well.  Any electrical geniuses care to tell me what that was about?

I've noticed a few "oddities" in regards to ground and lights on our bike.  Can't explain it, but make sure you use a dedicated ground wire.  That may help.

He's an article I wrote when I installed my Stebel on my Royal Star Venture - the Wolo is a "clone" - basically the same thing.  Hope that helps.
