Can only start bike in Neutral

fjmartin · 02-26-2017, 12:13 AM

I was out on a ride today and at one of our rest stops I put the key in on like normal, flipped the kill switch to RUN, pulled the clutch and hit the start button and NOTHING. Played with the key and run switch and that didn't help. Then I put the bike in neutral and it fired right up. Ran great. But I can repeat this over and over.

I'll call Gerry on Tuesday and ask what to look for but wondering if you folks have any ideas to look at?

Thanks!

There should be a diode attached to the wiring harness somewhere. When that goes out it will cause your symptoms.

I would check the clutch switch as well.

For the starter relay energizing circuit to complete it needs to ground through either the gear switch in the neutral position or the clutch switch closed ( lever pulled in).

My simplified wiring diag below , hmm, helpful or confusing, I can't decide

if there is a diode where you put it...
the starter button is feed with AC current
from the rectifier.. not DC from the battery as you have it drawn..
unless the start button is very big and can handle the DC amp draw..

the start button on these is fed DC, because they actuate the solenoid that does the heavy current Pete, AC power would only be occurring when the bike is running...

A bad diode will only make the neutral light come on when pulling in the clutch. But this was on a Hawk. May be different on other bikes.

That is by design so you dont start it in gear. Same with my bike. Also so if you remote start it you dont have your bike take off with out you lol.

Joe, check the connector for the clutch switch to be sure the pins are making contact, some of the various connector pins have been reported to have not been fully seated and work out of the connector body.

If there is good connection there, test the clutch switch with a meter.

If the side stand is down, it won't start in gear, regardless of clutch lever position.

Thanks! Doing a full clean of the bike today and will check the switch out and use my multi-meter on it. It got filthy yesterday. I'll post the video of the ride soon.

Ben, the RX3 doesn't have a side-stand switch.

I responded to this before watching your latest video.

Your go-down laid the left side in the dirt, possibly the clutch switch/wiring took a love tap at that time.

Really? That's good info. I'm not sure if the missing side stand safety switch is good or bad. Maybe bad for a new rider, but those of us that have been riding for a long time know to make sure the stand is up.

Jay, The issue started before the crash. After I got the bike cleaned up today I started going over this issue. I started with the clutch switch. First thing I did was unplug the wires and connect them together. Now, I could start the bike when in gear. So I know the switch was the issue. I unscrewed it from the bike and noticed that it was a bit sticky. so I tapped, pushed, wiggled the switch and tested it again on the multi-meter. Worked fine now. So I put back on the bike and it's working. I'll chat with Gerry and see if he thinks I should replace it or not.

Ben, I was originally going to add a sidestand switch. Another person on this forum had done it and I was going to copy them. After speaking with some friends they recommended not as they had disabled theirs on their branded bikes.

I have only disabled mine for a few reasons. The main one was to continue riding. Another was the expense for a new one just not being worth it. The only other one I can remember right off is the unavailability of a replacement.

I have accidently left a side stand down and wrecked myself, slow speed flop. It's been quite a long time since I have done that. I got into the routine of popping up the side stand, as soon as I get my leg over the seat, and plant my foot.
