Is that a ring around its mounting bolt? So the ring/mounting bolt/mounting bracket is grounded? (My 2011 LEAF gets its ground from a wired negative connection, not from its mounting.)GlennD wrote: It has 12v and the horn ring supplies a ground.I don't know, but I would think it still has a relay. AFAIK, the stock horn on my LEAF draws 10 amps, which I think is quite a lot and needs to be switched via a relay.GlennD wrote:I do not think there is a relay anymore.
My 2012 Leaf had one lead grounded and the horn was supplied with 12V when the horn is pressed. There is no ground on my 2013 Leaf.
There is a foam block and lots of stuff in the way of top access on my 2013. Also the panel does not easily come off anymore.
Horn ring is siren speak from the units I repair. I guess at one time there really was a horn ring.
I suppose I could have listened for a click from a relay but I did not think about it.
