2009 GL1800 wont start because the reverse light wont go out

Post by snoopy chariot »



The wing has been modified to a Champion Trike so has no side stand.
10 months ago i put the bike into the shop who had it for 6 months. Replaced the handlebar switch block and replaced a cable that had parted and reset the tension. They got it to start about once every 3rd try but could go no further.
Sent it to an auto sparkie who also rides bikes who replaced the reverse module, and it now starts every 4 out of 5 tries. That 5th start will strand you. He seems to think it may be the reverse ICU.
Are they available? New? Second hand may be no better than what I have got.
Any other suggestions?
Cheers

this one should work

Verify the part #, but 2009-2010 are the same bike.

When it won’t start, is the reverse light on? If so, is it steady or blinking? If you use reverse regularly, the culprit may be the reverse actuator assembly. There’s a switch in it that goes bad and you get nothing but trouble out of the system when it does. I’ve only heard of a couple reverse modules going bad in the 20 years of the 1800.

In the early days the reverse light flashed while riding the bike. When the bike wouldn't start the light was on all the time. The actuator has been replaced with a new one, but it has made no difference.

Ok, has the reverse regulator been looked at? A little corrosion in its connector can cause weird symptoms as well. Does reverse work correctly when you use it?

Ok, you said earlier that the reverse module has been replaced as well and it shorten the failure occurrences. Were you referring to the reverse regulator? Has the cruise/reverse control module been changed? Has the 4 reverse relays been swapped to see if one is defective?

Ok, did the mechanic check the reverse switch on the right side of the block? If the cruise/reverse module was changed, there’s no other ecu or processor involved with it. If the switch on the block was checked and the cables are properly adjusted, then it’s a wiring or connector issue. The mechanic looking at it needs to fully understand how this system works and how it’s tied into the starting system to troubleshoot it. Even using the Honda service manual doesn’t make it easy. When it’s working correctly, does the reverse work correctly as well?

An auto electrician has had the bike for the past 4 months. He is a bike rider (both road & track) and is very clever. He has access to all the Honda data and it still has him beat. The reverse was working correctly before this happened.

What does it do when you try to start it and it fails, Just clicks?

It doesn't make any noise because the reverse light is on and wont go off.
It will start if it feels like it, but then wont start again for a month or so.

Ok, do you know if the actuator is moving to the reverse position and locking up the rear wheels before the starter button is pushed?

The bike is currently in bits, however it was possible to push the bike even although the dash was showing the reverse was supposedly engaged.

Ok, the reason I asked, is there’s really no way for the cruise/reverse module to keep the bike from starting unless the actuator is not fully in the neutral position. There’s a switch inside the actuator that has to be closed to send power to the neutral light so it can turn on when the gear position switch and the tranny is in neutral. This same power for the light is also required for the reverse relay to energize and send a ground to the coil of the A starter relay. Do you get a good neutral light as well as the reverse light at the same time? Another issue the actuator being slightly out of position is the reverse switch on the right side of the block. If the actuator is off just a bit, it will have the internal parts of the engine in a position that will cause this switch to be open and not providing a ground from the switch to the coil of the B starter relay. If this was the case, you would hear the A starter relay click, but the B relay would fail to energize without it’s ground.

Ok, so, there’s either an issue with the power for the neutral light and the reverse relay or there’s an issue with the gear position switch and the ground for it. If you were in KY, I would have you on the road by now. Just ship it over here and you can tour the curvy roads of KY after I fix it! :D

Wish you could fix it!! America sadly is the last place we would want to be at present. Don't really want to spend any more money on it now. It will probably become a white elephant now, like a lot of others around the world. Good for parts.

I understand, some days I don’t want to be here! Don’t part it out, if he gets it put back together, I can walk you through fixing it online. It might not be fast, but it will be better than just cannibalizing it. That’s just sad to kill it over this issue. :(
