Removing ignition switch

Postby tom.believes » Sat May 21, 2016 4:49 pm



I need to remove my ignition switch from my 1984 gl1200 and can't find any detailed guidance on how to accomplish this. I've removed the false tank, handle bars and can't figure out where to go from here. My service manual says to remove the fork and handlebar bridge, but I can't figure out how. Can someone provide a little more information?

Its been a while, and I have slept since removing mine on my 85. But didnt take the bars off. If I remember right the bolts are on the bottom. I had to remove an odd looking metal piece from between the forks up inside the fairing bottom. Didnt put that back cause it was a pta to remove. Then I used my 12" long 3/8 extension and ratchet. if memory serves me well. ;) . hope this helps.

Thanks for the speedy reply. I saw that piece of the faring, (I guess), blocking my access to the bottom of the switch, and made the decision to go the route my service manual suggested. There is a locknut that requires a special socket to remove the fork bridge off of course. I'm halfway there I hope so I'll see if I can get the locknut off and gain access the the switch that way. I did discover that if I put pressure on the bottom of the switch with my finger, the contacts in the switch made.

So, what goes bad in these switches? Is it due to weather/rain getting in there causing corrosion? Or do they break internally?

Apparently it's an internal issue that Honda had to do a recall on. This was a huge pain getting this switch out; I'm not sure how I'm going to get one back in and still be sane. I think this is the original switch from what someone posted about what the replacement switches look like and I doubt a recall would still be in effect on a 32 year old bike.? Besides, I've got it torn apart now so I think I've boxed myself into a corner.

I think any electrical part that lastest 32yrs is doing very well. And all the turning back and forth. On/off and to lock and back. I just replaced the ign. sw. in my riding lawn mower and its 5-6 yrs old. If you figure a battery only last 4-5 yrs. and cost $80-100. Just sayin....... :roll:

OK, I was able to remove the ignition switch from the bottom as per twocams method. Still a hard process and one that I hope to never have to repeat. Once I got the switch and carefully took it apart, the problem was obvious. There was considerable corrosion on the contact points that was causing a bad electrical connection between the stationary and spring loaded contacts. Two contacts in particular were overheating and the plastic housing was showing some slight overheating and causing the contacts to stick instead of springing back and forth as they slid over the stationary contacts. Some emory cloth, solvent and an exacto knife cleaned and freed up the movement well. I also slightly adjusted the springs under the contacts to insure they made good contact with the stationary contacts. I did this because before I started all this I was able to put a little pressure on the bottom of the switch, causing the contacts to mate better and the switch worked properly. I applied a bit more grease where grease was already in use and reassembled the switch. I took it to my poor disassembled bike and plugged it in and tested the switch several times with good results.
I will probably take the switch apart again before I reassemble everything and clean out the old grease and go with totally new. I don't know what grease was used originally, and I mixed two different types together which is never good. I think a good dielectric grease will do fine, and there was no indication of water intrusion.
Thanks for the advice!

Thanks, sounds like a yearly shot of Deoxit in that switch would be prudent . May save a bunch of work.

Glad to see that someone else has seen the good use of Deoxit. Good stuff!!
