I have spent countless hours working on the wiring for a friend's bobber and can't figure out why the starter button only works intermittently. He has a 79 bike with a new 78 wiring harness (don't ask) that uses an aftermarket turn signal/light/horn button switch. He chose to go with no on/off switch too to complicate things, so it only uses the ignition key as a shut off. I wired the thing up using the diagrams downloaded from this site for a 78. Never could get the coils to work with the harness in any configuration so I wired them up direct. The bike kick starts fine. The starter switch worked at one minute and then nothing the next after making no changes. I checked all the connections and they seem fine. Even taped the starter button on while I messed with every connection and nothing. The button is activated by the blue/white striped wire off the relay and the hot wire on the ignition. I even tried bypassing the switch to see if it went bad (brand new) and nothing. Replaced the relay and nothing. The other strange thing is that with the key off and no lights on, the battery loses it's charge as if something was left on all night.
Any suggestions (other than chucking the harness and rewiring the whole damn thing)? He paid $90 for the harness and would like to make it work.
