I bought my 03 in May, and didn't realize the reverse was not working. Wanted to enjoy the bike through the riding season, so I just started digging into it last week, as the riding season is over.

Symptoms: reverse light comes on steady, but when pushing the starter button, reverse would engage for 1 second, the rear wheel moved about 1", and something loud could be heard tripping off, reverse would stop immediately, and reverse light would go out. To try again, it was necessary to turn off the reverse switch.

After pushing the reverse switch on again, I could hear repeated, fast ticking coming from the relays' box. Specifically, if I touched the RVS relay (fourth from the left in the bottom row of relays), I could feel it clicking, which told me that the relay's coil was not getting good 12V voltage for the contacts to stay closed.

One side of the coil goes to the reverse regulator module, and the other goes to the reverse control module. So, I figure the problem could be at either end.

The reverse regulator is accessed by removing the left saddlebag, and it's located just under the top frame member on the left side of the rear fender. You don't have to completely remove the saddlebag, it's enough to remove the 4 screws holding it in place, and wiggling it out bottom first, just about 2" from the frame. first it is necessary to remove the rear center plastic piece between the two saddlebags (where the license plate is located).

After carefully removing the regulator from its rubber mount, and unplugging it (connector wiring and module really badly covered with 11 years of road dirt), I found that the 2 pins at one end of the regulator connector were badly corroded (covered with a green substance). I carefully cleaned the tiny pins with a sharp blade, being careful not to bend them, and pushed a bunch of dielectric grease into the female connector end. Plugged it back in, and tested the reverse again: it worked!!!

Just thought someone might benefit from knowing what I found to be the problem.!

Excellent work and worthy to become a sticky.

Thanks! I think this module could be the reason for other problems as well, due to its lousy location on the bike.

Good stuff, mine has been acting up a little bit, but more of the gear thing sometimes I have to click back to neutral then turn the reverse back on for it to work

I subsequently wrapped the reverse regulator box in electrical tape, before placing it back on the rubber mount. If I were you, I would take the little time that it takes to slightly separate the left saddlebag, to remove, clean the pins and apply dieletric grease to the conector. A few systems depend on this little device to function properly. good preventive maintenance.

Thank you for the feedback, I am not having a problem at this time, but your struggles have saved a lot of guys here much time in diagnosing if their symptoms are similar. I may do as you suggest and spend a little maintenance time checking, cleaning and greasing the connectors. Thanks again.

Awesome information - might make a complicated troubleshooting procedure a little easier for the next guy :upthumbs:

Thanks Les,
It baffles the mind why mother Honda would place that module right where all the crap gets flung up by the rear wheel, and besides, not to insulate it well enouch against moisture penetration. I found two of the needle-like pins completely covered by green corrosion.
Well worth taking a look at it by separating the left saddlebag a couple of inches from the frame, and having a look inside the module connector, even if you haven't had any malfunctions yet.
Cheers,
Dan

Reverse

Thanks for the info. That may solve the problem I'm having. I was going to post this:I have a 2002 GL1800. When I put it into reverse, it clicks and barely moves backward, then sometimes does fine when I push the button. Any thoughts? But now maybe I don't have too.:hmmm::hmmm:

Buff don't have an 1800 but sounds to me that the switch isn't making good contact some times. Try cleaning it with Electrical contact spray, the blow it out with some canned air.

As always this is just one Ole Fossil's opinion

Already tried that, to no avail. Thanks for the idea though.
Then maybe one of the 1800 guys can help. Don't know enough about them, sorry. Are there any relays in the reverse circuit? One would think so and quite possibly the contacts are cruddy or pitted not making good contact.

Problem with reverse

I have a 95 Goldwing that the reverse acted up the other day backing out of the building I had it in while we were working on my sons 98.I have backed it out 3or 4 times before. But last Sunday when I went to get it out and pressed the reverse switch it moved may be 6 inch's or so. pressed the reverse switch again and it moved about 6 inch's again. Pressed the switch again and it backed out but then I smelled something that I thought at first was antifreeze. But then I decided it was something getting hot. Haven't stated it since. After reading what was said about the reverse module I'm wondering if I have a problem there. Anybody had a problem like this?

Dirtman, the OP listed his issue based upon an '03 (1800), since you have a 1500, my guess would be that it is a totally different issue. PM ole fossil and see if he has a cure for you (his is pretty slick on info for those 1500's) or start a new thread titled "1500 reverse issue" and maybe you can get more attention that way. Hope that helps a little. I sold my 1500 years ago and don't remember crap anymore.

I have the exact symptoms. I looked at the reverse regulator and couldn't see any obvious problems. Sprayed it with contact cleaner and blew it out with compressed air.
Tried reverse again and no joy. I'll keep looking. Thanks for the tips!

reverse fix

On my reverse problem, it was the A and B solenoids that lost connection at the plug. That lasted for a short time then had the gear position switch replaced after losing its ground and that solved the problem on my '02 1800.

Buffdaddy55: I had the clicking issue. Took it into the shop (warranty). A quick fix. Something about a cable not being properly adjusted.

You know how you take an intermittent problem into the shop and can't reproduce it with the mechanic watching? Didn't happen here. It was a wonderful feeling to have it fail right there. Even when the GW acts up, it satisfies.
