Reverse Dash Light Flashing

Post by Eboness »



I’ve been very lucky with my 2013 GL1800 level IV, so far very few issues I could not sort out quickly. However the other day while on a short weekend trip my wing would not start and I had already been riding it for 20 minutes. I did the usual things to check, side stand up, kill switch was in the run position, but then I noticed my reverse switch dash light flashing. Since I was trying to start my wing that was not in neutral with the clutch handle pulled in I decided to put the bike in neutral. It started right away and the reverse light stopped flashing. For the rest of my trip, no starting issues. When I got home decided to do some research into reverse switch dash light flashing. Here is what I found out. Turns out, over time, at the neutral switch assembly the wire connection can become loose because of the nut holding it to the switch can back off. You can find it under a rubber boot just above the oil dip stick on the right side of the GL1800. On my check, found the nut had backed off so much that the loop connector was very loose. Tightened the nut and have had no issues since. I going to make a permanent fix by changing this tiny nut to a nylon inset nut which should prevent future problems. If I were you folks take a couple minutes to check this connection before you have my issue. Remember hand tight only as the threaded stud is very small and it could snap off the neutral switch assembly and you would need to replace the whole switch. I’ll try to make a quick video to show where and how to check it. Ride safe everyone.

Thanks for this great advice. I tend to use some Loctite on any fastener that I find works itself loose, that usually solves the issue.

thanks for that heads up.

my 2002 has not given me any trouble at all, since I bought it used over 5 years ago.

It has been PM'd once and time for that again.

New tires, Air filter 2 years ago, and this year, it has only consumed 4 gallons of gas :roll: :x :o :shock:

time to correct that little problem as soon as it warms up, I am going for a ride.

Good catch, just for clarity, the switch on the block with the rubber cover is the reverse switch, it grounds the wire when not in reverse and removes the ground when reverse is engaged. The gear position switch in the front engine cover handles the neutral functions. :D

Hi Techdude2000, Thanks for the clarification on this switch and how it works. The only reason I called it a "Neutral Switch Assembly" was thats what Honda Powersports OEM parts Fiche calls it as shown in this pdf. However I would suspect you have more knowledge than me on the correct discription, thanks again.

Yep, the parts list description is that way because Honda has used this same part number and part as an actual neutral switch on previous bikes. On the wing, it provides the ground for the B starter relay. If the wire gets loose, it makes the system think the reverse mechanics inside the engine are in the reverse position, but the reverse shift switch on the handlebar would be telling the cruise/reverse control module that it’s not in reverse. This triggers the flashing light and the dead starter button function.

Thanks again Techdude2000, your newest discription really gives me a much better idea on how the system works.
Happy New Year and ride safe.
