Red face Starter Solenoid Fused?

Does anyone know if there is a separate fuse on the starter solenoid. Not part of the Junction box.. I hear a clicking in the junction box that does not seem to be coming from the solenoid. 1986 Vn 750 died suddenly one day and now the starter button only produces a click in the J/B. Battery was tested good by a reputable bike shop. Help...

No separate fuse on solenoid..... only bikes main 30 Amp affecting ignition switch.

Check electrical connectors at JB.
Also, Possible bad battery, bad battery cable connections / grounds, bad JB (?), dirty/defective Ignition Switch/starter button contacts......

Yea I'm cleaning out all the connectors tonight and going over all the wiring that was mangled by the previous owner. He added ground effects and a neon light bar and the wiring job was way below par. I'm uninstalling all of the above as I'm troubleshooting this issue. Thanks for the quick reply!!

I cleaned up all the connections and am able to jump the solenoid and make it crank. Starter button makes the J/B click but doesnt crank.. all the safety switches seem ok.. Any ideas?

Examining the schematics, my next thought is the Ignition Switch and/or Grip Starter button internal Connections / Grip Electrical cable Connector...(behind headlight / & neck covers)

some here have discovered turning the Bars to the right (or was it left?) allowed bike to crank/start....iirc...problem was in those connectors.

to sum up, The headlight can be intermittent and the headlight indicator also seems to be intermittent as well. In my mind, as long as I'm hearing that JB click, I should have power from the bars to the JB. I was thinking it was the JB internal relay that may be the issue.. I certainly need to check out the connectors behind the headlight and inside the headlight assembly to TS the intermittent lights, but I dont understand how this could keep the solenoid from being activated.

Also when the bike initially broke, it stalled out, I started it back up using the starter button, it stalled again and then the starter button stopped working... Maybe the relay in the JB box went bad grounding the system???? Im so lost...

There is a starter system relay in the JB.

I suggest you pull the right side cover, if you haven't already. Neutral, key on and push the start button. Test for power on the R/Y (I believe) wire connected to the starter solenoid.

Get back to us.

added-there should be bat cable in, bat cable out to starter, B/Y (grd) and either R or R/Y (switch).

edit- switch power to starter solenoid should be Y/R.

Good Post....why didn't I think of that approach ?

(If the bike was in front of me, a meter available, I would have. Sorry...)

I looked this up using my handy-dandy manual that I downloaded here for FREE.

pg. 15-29 and 15-30.

Ya could just bypass all the safety crap too like many here have....

That eliminates many variables....
