An immediate fix is to use the "Kill" switch.But do not forget to put it back to normal operation :o

Hello and welcome to the forum.
Many times the 'A' relay alongside the battery hangs up. You may want to disconnect the battery negative cable.

Hi everyone,

I had a similar problem the other day. My 2006 goldwing has the CSC 2012 trike conversion and I have owned the bike for 5 month(I have put 3K miles so far on it)
After a 1/1/2 ride the other day the bike would not shut off. I had to use the kill switch, which turned off the engine,
but the headlights and the neutral lite were still on. ( the display that shows the GPS, radio info did turn off with the kill switch.)
I disconnected the ground side of the battery, had lunch and the bike started up ok.
After I got home, I tried about 20 times ( turning off and on) and it always shut off with NO problems.
A question, where is the "A" relay that was suggested in the earlier post. If it is on the positive battery side, how do you get to it with the conversion kit on?
Also, the relay box under the seat is the "A" relay in there? And how do I remove the cover to see or replace the relays (it looks like there are 4 rows of relays with a green tab on each side for the 1st row and different colors for the other rows) Do you just push on the green tabs and that row drops down?

Another note on the problem, when the kill switch was used to kill the engine the neutral lite dimmed a little ( my guess is that with the engine on, the battery voltage was higher because of the alternator which is normal.)

Kip,
Hope this will help some.
Problem: Bike won't turn off with key. Kill switch shuts off engine, but neutral lite, tail lites and I think headlights were still on.

About 2 weeks after it originally failed, it did it again and this time I wanted to write down everything that was still on or working, BUT before I could start (I tried turning the key on and off a few times) it shut off like its susposed to.

When i got home and looking at the wiring diagrams I thought maybe it was the iginiton switch. I went to remove it to clean it and check it out, but it has security bolts (got to drill them out to get the switch out.. Forget that!
So on page 3-4 of the ETM I see where the ignition switch feeds a bunch of relays. One being the tail relay (remembering the tail lights still on), I wanted to try something so I swapped the tail relay with the heater relay(dont need heated grips in florida) and I also jammed a wire into the tail relay and brought that out under the seat (taped up) so I could see if 12 volts was there when it failed again. ( which would point to the ignition switch)

9 months later...... no failures at all.
Was it the tail relay? I am not going to swap the relays back. The wire is still there and I have my pencil and paper to document what is still on.

Also, After it happened the first time I ALWAYS use the kill switch first and then turn the key to off.

Good luck
Jerry

I literally just walked into the garage to take the seat off when I got your reply. :D
Mine is doing the EXACT same thing as yours did.
I'm going to switch relays and see if it goes away.
I will update on my status.
Thank you so much for replying!

OK... I found that when I turned the key off, the engine and power would stay on until I removed the high AND low beam relays. I can also power down by removing the same two fuses.
I switched the accessory & horn relays with the hi/lo relays & NO difference at all :evil:
Nothing to this point has caused the headlights to come on, or turn signals to flash.

Moisture/corrosion in the headlight plug?
Grrr

I know this is an old post and I hope these bikes have been fixed, but just in case they are still having this problem or there’s others with the symptoms. I helped a guy find the culprit to this symptom on his 2003. It turned out that if he had the high beams on when he turned off the key, the bike would remain running, but if he didn’t have the high beams on, it would shut off with the key. So, we found an issue with the ground circuits in the fairing harness that allowed power to back flow from the high beam indicator in the gauges and keep power on some of the relays that are normally dead with the key off. The fix was to replace the fairing harness. There’s junction connectors in it that develop bad connections and cause the back flow power into the ground circuits. Hope this helps someone in the future.

I also found the problem with the ground. It was the gang connector on the left side under the upper vent. Water has been dripping through the vent and laying in the connector causing corrosion and a enough heat to deform the plastic.
I had to remove the ground from both sides and connect directly.
I unhooked the gang connectors on both sides of the bike and moved them under the fairing to avoid water from dripping down on them.

I've recently had a problem with turn signal/brake light short.
It was under the seat, taped up in the main wiring harness, above the battery, toward the rear of the bike about five inches. There are a bunch of green wires that are connected together with a multiple pin connector, in a yellow plastic housing. I was able to trace it to one specific pin, but couldn't see any evident issue with it.
I took the connector out of the plastic holder, put it back in the lower plugs deeper than when in the upper holder and put the top cover back on. 7000 miles and I haven't had a malfunction yet. I'll attach a couple pics. I know I should've taken more/better ones. But at the time I just wanted it fixed.
It seems there are numerous wiring issues with the first gen 1800.

Yep, Honda failed to use good weather proof auto type connectors and caused definite aging failures. Wait until you get a bad connection in C5. You can lose the FI system and engine, tail lights and everything that uses their power, speed sensor, and just general bad running symptoms. It’s C25 in the 06-08 models. Same connector, new name.

Please tell me where C5 is, so I know where to look when it happens!

It should be wrapped up in the large harness right in front of the relay bank under the seat, it’s hanging out of the harness on some bikes. It’s blue and has 20 wires in it, but they are not all connected to each other. There’s 4 different circuits sharing the junction with special segmented shorting bars in its cap. Here is a good link to more info I have posted on another board. https://www.gl1800riders.com/threads/ni ... 25.420969/
