No crank after shorting out headlight

Everything turns on and works but I get nothing when starter button pressed. I was wiring and testing led bulbs for headlights and some wires touched and shorted out instantly. I head a "click" or "pop" noise come from the fuse box area. Checked all the fuses and they're all good. All wires look good and no smoke or burnt smell. I can jump the bike straight from the starter with a bump box. The starter relay switch and the rectifier were tested. Didn't test rectifier, but did test starter relay and it seems to be bad. I touched the positive and negative terminals and the starter turned over. So that would mean I need a new starter relay, right? Wouldn't the 30a or 20a fuse blown first?

I would start with a new relay and see where that gets you it’s not gonna kill your wallet so might as well. Also I would read up on your handbook and follow procedures on testing that system. I’m having electrical issues with my bike as well so good luck with your problem

No bikes shops around me have the relay (or correct one) in stock, so I ordered one off ebay that'll be here Tuesday. But my favorite shop went ahead and ordered a few so if this ebay one doesn't work, I can pickup a brand new OEM Honda one.

I've been told I can just jump it, but I don't like that idea. Especially if I have to take the seat off every time.

So I installed the ebay parted-out bike relay and it still doesn't start. Absolutely nothing when I hit start. I traced the wiring diagram from the starter switch and a black/red wire completes the circuit to the start button along with a yellow/red wire that goes to the starter relay. That black/red wire goes to the 20A headlight fuse and the headlight relay. I can't believe I didn't see the headlight relay since this problem did occur at the headlights! I feel dumb. I'm gonna go see if the headlight relay is shot.

Be sure to check the Bank Angle Sensor also. I saw a spark on start up near the dash. Engine then ran but would stall at full stop. Finally, she wouldn't start at all. Went thru standard "no start procedure" and identified BAS. Good luck with repairs.

Just checked the bank angle sensor. Works fine. I did test the kickstand switch by putting it in gear with it down and that's fine too, but now my guage doesn't show the bike's in neutral when it is. Now I gotta look into that issue.

Check the connectors in the dash area, maybe something was damaged by the over-current.

Jumped the starter button today and still nothing. I'm still hoping it's the headlight relay which hasn't come in yet. If that doesn't work I'll buy a new OEM starter relay in place of the ebay one I ordered.

I'm still tracing the wiring diagram around to find possible culprits. I don't get how I heard a pop/click under the seat area but no fuses blew or signs of burnt wires. The last thing I wanna replace is the regulator/rectifier, but the bike runs fine beside no starting with the button or headlights.

Everything looks good but my neutral light came back on after removing the connector and plugging it back in. Maybe it was loose from all the messing around I'm doing.
