I have recently installed the new Trail Tech Voyager GPS/Speedo. (I will post pictures soon.) Everything went pretty well. But when I put it all back together, my neutral switch (I think) is no longer working. The indicator light won't come on and the bike will not start in neutral alone as it used to. I can still get it started with the clutch in and side-stand up. I am not very good with electrical systems so I would really appreciate it if someone could help me out with troubleshooting this.
Here is some information about what I did that may have contributed to the problem... I hope talking through this will hint to a possible solution.
I installed the computer in place of the indicator light box so I could have it sit beside my stock speedo/odometer. It also made sense to put it here because I had lost the meter box a few weeks ago during my participation in the La/Barstow to Vegas ride. For the past few weeks, I had been looking at blank bulbs without the cover. All the indicators and the neutral switch seemed to still be working at that point. During the Voyager installation, I removed the indicator bulbs and sockets from the rubber piece and pulled the "SOCKET CORD ASSY" 15A-83509-00-00 away from that area and re-routed it. (I had a plan to modify and relocate the indicator lights.)
So after the install I put everything back together and started it up. The neutral switch still worked as I let it run with the stand down while I messed around with the computer a bit. I let one or more of the bare bulb sockets (maybe the neutral one) hit metal and it sparked and the headlight dimmed. DAMN. I had neglected to tape them up before messing around with the power on. So I stopped the engine and turned the key off. After securing the bare sockets, I tried to restart the bike but the fuse had blown. After replacing the fuse and trying to restart is when I think I first noticed the neutral switch not functioning properly. I had to stop working on it however, and I guess I forgot about it after that. (I usually only start with the clutch in and the stand up.) It was about a week later after getting LED replacements for my indicators. that I realized that the indicator would not light and I remembered the starting issue.
So now I am trying to locate the problem. I may pulled a bit on the wiring harness as I was moving the socket assembly. But it seems like all the circuits have continuity where I have tested and everything looks well seated. Although I don't not trust myself at all when It comes to electrical repair.
I feel like I am in way over my head here, but the problem is not stopping me from being able to ride and therefore not something I want to spend money on to take it to a shop. It is really just more annoying than anything else. But I hate having issues like this. It really eats at me and distracts me from other projects.
I guess I should maybe start by replacing the neutral switch itself (or the relay?). They are cheap enough. But I don't want to just start replacing parts not knowing that the problem is.
Can anyone give me suggestions to help diagnose this? I would greatly appreciate it.
I am not sure what your problem "IS" but I think I know what it "ISN'T". You mention replacing the relay. It more that likely isn't the relay. It would not start with the clutch in if it were.
