i'm tracking down a non working and now intermittent horn.
it looks like there are two electrically isolated spring mounted "bars" on the left and the right and four square bronze contacts (and a facing rivet) at the four "corners" here. i am going to go in on my spare wheel and Deoxit all of those to make sure they are clean.
also there is a black wire that runs into the connector that is mounted in the RIGHT bar only that goes to the connector to the clock spring (for the cruise control and the telephone on the LX450).
anyone know how test that wire for continuity? i use Ohm setting i think?
also anyone have any other specifics on testing this wire? the airbag will be off and the battery will not be working. can i reconnect the battery and test the horn with the airbag off while jiggling the wire?
anything else?
ALSO, anyone know how the LEFT bar triggers the horn? i can't see how pushing that left bar down would send an electrical impulse through the wiring to the clock spring and into the horn?
THANKS
