No spark - 1982 GS1100GK - faulty igniter?

[Guest]

yeah .. i did not pick up on that.
If you ever want to see a spark from any spark plug, it should be grounded.

I know...When I checked all spark plugs for sparks I always made sure that the one plug I was checking at a time was properly grounded to the cooling fins. While I was checking one particular plug one or more of the other plugs may not have been grounded properly and I was wondering if one or more non-grounded plugs could lead to damage to the igniter.

No, that won't cause damage.
The igniter takes a pulse from the pickups at the crank,
does its magic with it and gives that signal to the coil.
Igniters can fail, not often but they fail sometimes.
But it may just be the lack of proper voltage or other bad
connections are the cause of not functioning well.
(or failure, bad connections may cause higher loads running
through components and heating them up.
Sometimes you find the transparent outer part on a connector
brown or black or even melted from heat)

Please let me know what you think about these measurements.

that's bad contacts, should be solved.
If that means taking the handlebar switch apart, consider there's a lot
of small parts in there that want to jump out and hide.
Are you comfortable doing that ?

I am wondering what my next steps should be. Retest the igniter with pulled headlight fuse?

Retest is fine, as long as the igniter gets 12 volt

I haven't done this myself but it seems it could work.

As another ignitor test, if you can turn the engine over slowly enough, you might be able to see a low wattage test lamp flicker as the ignitor ("TCI") pulses to the primary...
I'm not sure of the rpm required to create a pulse you can see at the lamp but it's likely under a thousand RPM and I doubt you can do it by hand turning the crank...spinning the engine with the starter might be about right?
The test lamp would be in parallel with the coil connections..a bulb similar to your gauge lamps would be a "low wattage" bulb.

Test both coils.

ALL plugs are to be grounded whenever the ignition system is employed. Be aware that the secondary high voltage coil GROUNDS AT EACH END through two plugs in the four cylinder bike.....so you should have the PAIR of plugs grounded......Leaving one lying loose while you test one seems bad to me. Keep them in their holes until you test them one at a time. As to igniter damage if you don't do this, I don't know, but some people say that it does...simply speaking, you're playing with lightning when you "experiment" with high voltage coils.

I opened the right handlebar switch and cleaned the kill switch with Deoxit, sprayed Deoxit also onto the starter button, but did not take the kill switch and starter button fully apart. Should I take both fully apart? Are they more difficult to reassemble than the ignition switch, will there by flying parts?

I took the ignition switch apart and cleaned it, was holding my breath when I opened it, but was able to reassemble it without major difficulties.

I retested the igniter. I pulled the headlight fuse, which allowed for 12.2 V going to the igniter. I performed the igniter test with a 1.5 V battery and got no spark on any of the plugs.

Based on this it looks like to me like the igniter is faulty. Please let me know if you agree.

Based on what I found on this forum and elsewhere I am inclined to get an aftermarket ignition system. Would the Dynatek 2000 be the right system for my bike?

Or should I consider getting a new (=costly) or used OEM igniter?

Thanks again for all your help

Then you should be able to do this.
Some place a bag around the switch to catch flying parts, the starter button spring tends to jump out.

Looks like the igniter is fried ...

The Dyna 2000 is a great device but costly, and takes some rewiring and has a control box you would need to hide somewhere.
Personally i would find another igniter.

 

[Guest]

Thank you. Which Dynatek model would you recommend for my 1982 GS1100GK?

Are there any good alternatives to OEM or Dynatek?

 

[Rijko]

The only Dyna alternative is a Dyna S, cheaper and good, but that would mean installing a mechanical advancer.
Don't think that would be a problem, but i have no experience with that.

Not many alternatives for OEM or Dyna.

 

[Guest]

OK, thank you. I will also check for used ones on eBay.

Give these people a call.

Thanks, everyone. I found an NOS OEM igniter, same type as the one on my bike on eBay. Wasn't cheap, but they offered me a discount after I put it on my watch list. This will take out the guess work.

In the meantime, I am cleaning up the remaining connections. Took the starter button apart, was easier than I thought. The copper contacts are slightly blackened. Will give them a good cleaning. Fingers crossed!

Congrats, hope it will run well.
