Reverse Mode Failure

Post by Piddler »



Hello
I got my (New to me) 2002 GL1800 running with a new solenoid and some practice taking the bike apart and putting it back together until I got it right, It starts quickly and runs great, I put a new front tire on yesterday but when I rolled it out and put it in reverse, which has been working fine, the reverse light comes on but when I push the starter button it lurches backwards for a fraction of a second and the Reverse light goes out and the bike stops. I then have to undo reverse and push it again for the same result Does anybody know what's going on?

Did you replace both starter solenoids/relays or just the A relay, closest to the battery? One possibility is the B starter relay has welded its contacts and this will cause the reverse system to shutdown immediately. I saw where you just recently got this bike and it failed to start right away. Are you sure everything was reconnected correctly on the starter relays? Here’s a diagram to help with the cable connections.

Actually I replaced the closest one as you mentioned before I realized there were two. I tested the voltage and it stopped at the out terminal of the primary solenoid, the one furthest from the battery. I replaced the secondary solenoid and put the new one in the primary position. This fixed my problem, the bike starts as it should and for 3 or 4 days reverse worked perfectly. I don't see any correlation but when I put a new front tire on reverse quit working and just lurches backwards and shuts down. So, you think it's the secondary solenoid. (I'm calling it the secondary because the 12v power goes through the back solenoid first them through the one closest to the battery. I believe.

I just tried reverse while on the center stand and it worked so I pullei it off the stand and now reverse seems to be working fine. Go figure.

Using my diagram above. If it’s wired correctly, the power leaves the battery, and goes to the yellow arrow connection of the A relay. It connects through it and leaves on the purple arrow connection and loops to the B relay’s lime green arrow’s connection. It closes and connects to the candy cane striped starter cable on its rearward post at the teal/red arrow. When we see these going bad, it’s advised to change both at the same time. They are both used for starting the engine and they both can pit and weld their respective contacts causing issues. If the A relay welds it’s contacts, you get a starter that continues to run with the key off and if the B relay welds its contacts, the reverse system will shut down like your symptom. Intermittents can make you crazy, I would go ahead and replace the remaining original one with a new one before it either burns up your starter or fails to start again.
