So I haven't seen this one before on the forum and I could use some help.

Here is what happened on start up I turn the ignition to on the headlight is working, it turns off when I press the starter button and never comes back on. Brights are gone too.

So checked the bulb, its fine, checked fuses they are fine, checked for voltage at the plug nothing, checked the switch its fine.

So the question is what part interrupts the headlight circuit on start up?

Thanks guys ~LH

 

Check the contacts on the starter switch. There is a set of contacts that disconnect the headlight when you push the switch so you have more voltage to the starter.

 

what is the checking procedure on that?

 

just disconnect reconnect?

or is there a reading?

 

On the plug where the starter switch plugs into the harness you should have continuity between Bu\W & Bl\R with the switch in the "normal" position and it should be open when you press the switch.

It's on the lower right of the schematic or page 19-20 of the service manual

 

Yeah, minimal testing equip and manual at the moment since I am 200 miles from home. It appears the relay may be faulty on that circuit I am just going to have to run a wire direct to get myself home but I thought it was worth a second opinion.

 

Looks like the starter switch is what turns the lights off when you start it. Checkfor voltage at the blue/white wire coming out of the starter switch. Or just check for continuity between the blue/white and the black/red wires through the starter switch with the connector dissconnected.

 

Sounds like there is an echo in here....

You can always put a jumper wire between the Bu\W & Bl\R wires at the plug and they should turn on.
or are you running one of the aftermarket relay kits? Though you are probably already on your way home by now.....lol

 

Same thing happened to me I use some electrical contact cleaner sprayed it in the switch housing while working the switch lights came back on. Contacts get dirty.

 

make sure starter push-button comes all the way back out after pushing it in to start bike to complete connection.pull it out with ur fingers or screwdriver.my interceptor was like that.they do wear out from constant use
