Wanted: Bad Igniters

[justmount1]

i am getting ready to take my ignitor off of my 81 kaw 440ltd i think it is bad ditto on what khrys771 said

[oldschoolorange]

Is there any way to make a device that would put the smoke back in them?
I have been busy as hell for the last bit but as soon as I have things sorted out I will got going on this

if you can figure out how to get the smoke back in to an electronic device, you will be more than a hero, millionare, etc!!! Even i'd love you, hug you, whatever!!!

Don't you know smoking is bad for your health; that's why I had to get out in front of the two-strokes back in the day!

[pvtschultz]

I'm almost positive the ignitor on my '82 GS850G is bad if you're interested.

Ok boys and girls!!! i've troubleshot 2 igniters, p/n 32900-45110. one has a bad scr that feeds the coil. shorted out. the second lost 2 transistors that provide drive to the scrs. Now all i have to do is get the parts! i am also working on a simple tester to verify if the igniter is working while on the bike. more to come.....

I'll Send You My Bad One From A 83 Gs550e, Send Me The Info To Get It To You.

[saddlewarmer]

Just a bump to keep it going. Still working on it and waiting for some parts!

[novacane]

the igniter is not firing the coils which fire #1&4 cylinders on my 1982 gs1100.inside you can see where it has been hot and the circuit board is burnt.i replaced it with one from ebay that they said came off a running bike but still no fire to #1&4 .................any thoughts

Excited To Hear Your Intentions To Fix Old Coils!!

I'm not trying to make a bunch of money on this. figure if it works, i'll charge for my time to fix plus parts. i know the feeling of needing to fix something and not having the money to do so because of the high cost of an item. hopefully, as some say, this is a way i can give back to the gsr.

i ALSO OWN A 1982 GS1100 GLZ AND ABOUT 1 HOUR AGO I FINISHED PUTING MY CARBS BACK ON AND WENT TO FIRE IT UP ONLY TO FIND VERY LITTLE TO NO SPARK AT ALL.CALL ME LUCKY OR UNLUCKY AS THE CASE MAY BE, BUT I WOULD BE INTERESTED IN TAILKING TO YOU MORE ABOUT THIS VIA E-MAIL OR PHONE IF YOU WANT TO.i HAD THE BATTERY OUT OF THE BIKE FOR ABOUT 2 WEEKS BUT APART FROM THAT DID NOT TOUCH A THING.WEIRD !!!(APART FROM CARBS)IN CASE YOU WANT TO EMAIL ME IT IS stanos@shaw.ca OTHERWISE I WILL TALK VIA THE GS RESOURCES.
THANKS ANDREW

i will try them all. i'm actually trying to draw a schematic from the board. will let you know more later.

Hi,
Would it be possible to let me have a copy of the schematic? I would like to prepare some backup in case my 28 year old gives up the ghost.
Thanks

Guy's, 90-95% of the problem with the GS igniters is the "coil driver" transistor---there is one for the 1&4 cylinders and one for the 2&3 cylinders.

Most of the time, when they short out, this cause's the box to

"let the black smoke out"
The box will get VERY HOT to the touch---it will almost burn you if you touch it with the power on for minute or so.


The original transistor has a part # d997 on it.

There has been a number of different "replacements" for this number but most every number has been discontinued also. (2sd977 as one example)

I have located a replacement transistor, I can ship it to your door within the con. US for $12.00 if this helps anybody...This is my cost and I am just trying to help out others on there repairs to the old ignition.

Hope this helps

John

here are a few things that can be usefull. it mite give you a ideal or two.

Hello there!!

So is this a common problem across all the bikes from 550 to 1100?

I've expierenced the same problem as a few of the guys on here who have only 1-4 or 2-3 firing. I swapped the wires from the one coil to the other then the problem was reversed. Is there an aftermarket igniter for the gs650?

thanks again gentlemen!

I wont say common, but not unusual. 30 year old components, exposed to the elements and maybe also to some mechanic or electrician. Coils replaced over the years with non standard etc. Most electricals have marginal rated components and can easily fail if more current is pulled and they overheat.
The igniter is definitely fixable and the components are cheap.
I just need to identify the diode marked 350 accross the darlington pair, then I could make the schematic available to interested members on the forum
