Possible Substitute Igniter?

I have found a box for a 1993 Honda Nighthawk 550. From what I can tell, the bike has the same type of ignition system. Air cooled, 4 cylinder, 57x cc....closest match I could find to the 1985 GS 550. Any reason I couldn't figure out the wire routing/positioning. Place the wires in the corresponding positions and hope for a spark? Any bets on the outcome? I don't see a reason that the two boxes wouldn't be very similar in production. I have been trying to find a wiring diagram for the 1983 Honda 550, but haven't had any luck. I also haven't been able to get the honda igniter out of the box like I did the one for my bike.

I tested the new box in the same "table" form that the manual suggests for the stock box. I made a table just like to one that was built in my service manual and compared. The wire configuration is obviously different, but I can't follow the patterns close enough to figure it out. I also think that where the Suzuki box has one ground wire on the plug that goes to the signal generator, the Honda box has two. I don't see another ground being a problem though. Other than that, I don't see how different they could be. However, I don't know anything about process that is going on inside that damn box either......

Advice?

may the force be with you as you sail through these unchartered waters :twistedevil:

Surely someone else has tried this? Or something similar? I will let you guys know what happens if anything at all. I have to try something while I wait for something else to happen, or I can stumble on a replacement that doesn't cost hundreds of dollars. This bike was just a winter project to tinker, not an investment. I have a guy looking at the original box from the scoot right now, I will see if he can fix it. In the meantime, I will be tinkering with this honda box....maybe. I need a wiring diagram from a 1983 550 Nighthawk.....I think that was the only year they made the 550, other than the CB 550's, but those are different I think. Anyone have one that could answer some wire color/placement questions for me?

All we ask is that you videotape it and post it on you-tube when it explodes. ;)
 
Well, at the very least I'd try to determine the coil amp draw on the Honda, just to make sure you don't get in the habit of smoking ignitor boxes. Maybe, go on honda forum and ask nicely!
 
Not too handy with videos, but I will take a few still shots if possible. Hard to do with a beer in one hand a tool in the other.
LOL! That is where Bubba comes in handy. "Hold my beer Bubba, and watch this."

Anyone elaborate on this point a little? I'm not sure how to go about finding out this information, or what it means. I'm less than educated in the area of electricity.
 
The ignitor is used to trigger the coils. There will be some small current draw to activate this trigger. There is also an impedance in the circuit which plays a part, since I = V/R (current = voltage divided by impedance). Voltage is constant at 12V, so if the impedance of the circuit is smaller on the Honda circuit the current draw will increase, which will tax the ignitor circuitry.

Just to clarify the gist of these 3 pages of postings, here is what you have/need:
You have an ignition system with an electronic advance. This electronic advance is built into the ignitor. This curve will vary model to model. For example, if you use an ignitor from another model with an electronic advance (I won't even go into using one from another brand) then the advance curve will be different. I put an 85 GPz ignitor on my 83 GPz because the advance curve offers better performance overalll.
What you need is an ignitor from another Suzuki that also had an electronic advance. I would strongly suggest another mid-sized GS, as this would increase the likelihood that the curve would be "close enough".
Have you tried fleabay?
 
Have you tried fleabay?

I have an a**load of saved searches looking and emailing me daily if anything that matches shows up. Fleabay is exhausted at the moment. There is one on there that matches the one for my bike, but would cost me more than I have in the rest of the bike. Not willing to do that.

Something will open up, I'm sure of it.
 
Just for my own curiosity, how much would that one cost? Unfortunately, these old bikes will not have parts that can be bought cheap if you are trying to get it running. I'm not saying to go out and spend $500 but $50 or $100 is not that bad considering some parts are not going to be found.

When I say that please don't think I have money to blow. Trust me, I'm about as broke as the next guy and I have a laundry list of things I need to get to ensure my bike stays roadworthy. Unfortunately though, I understand some of them are expensive and I'll pay the price when the money frees up (hopefully after my court case I'm starting).
 
I think it's somewhere around $250-$300 for the one on eBay right now.
 
That is an insane price, don't pay it. As an example, I have one for a mechanical advance 650/850. I want $25 for it.
For an electronic advance unit, I would expect to pay around $50, which is what I paid for my GPz ignitor.
 
Hey, I just ran a search for you and think you can expand your look area. These are the bikes that used your igniter if you have any junk yards close by:

GS550E (1983)
GS550EF (1983)
GS550EF (1984)
GS550EF (1985)
GS550EF (1986)
GS550ES (1983)
GS550ES3 (1983)
GS550ES3 (1984)
GS550ES3 (1985)
GS550ES3 (1986)
GS550ESE (1983)
GS550ESE (1984)
GS550ESE (1985)
GS550ESE (1986)
GS550ESF (1983)
GS550ESF (1984)
GS550ESF (1985)
GS550ESF (1986)
GS550ESG (1983)
GS550ESG (1984)
GS550ESG (1985)
GS550ESG (1986)
GS550L (1983)
GS550L (1985)
GS550L (1986)

It seems that even that 81 550t would never have worked for you but at least now you can have a better selection of bikes.
 
like i posted...
83-86 550 L/E/ES.
thats the only one that will plug and work on your bike without any modifications.
FYI
these boxes are HUGE money new.
4-5 hundred/ maybe more.
i get 200 hundred for the 1150/750/700 boxes which is less than half of new.
i sell one box a year to locals that call me after they went to the dealership and had a heart attach.
50 bucks for an electronic advance box would be A STEAL.
the 550 boxes are near impossible to find and if you do there is a good chance that they are bad.
these bikes eat igniters!

This gives me a great reason to find a suitable substitute if possible. I still haven't been able to get a wire diagram for the 550 honda, so I haven't ventured any further in that direction. I am going to find a Suzuki igniter within the closest range that I can manage, and buy it. I have hope that there has to be an alternative way to get sparkage to this old 550 again. It will be interesting to try anyways. I may even slip up and learn a thing or two along the way.

:eek:

As always, suggestions and recommendations are always welcome.

Wow. For that kind of money I'd convert to a Dyna 2000 and be done with it. Best of luck, User.
BTW, I believe that mechanical advance systems can be converted to electronic systems, can't he convert from an electronic advance system to a mechanical advance system?
 
From what I gather, there isn't a Dyna Setup for this bike.
But I think I have read about people making one fit by switching a few things around, and cutting a hole in the signal generator cover....not sure if that was for this specific model though.

Personally, I would call Z1 and see if they have a solution. If they cannot help you, then you are destined to wade the morass of low availability = high prices. Or rebuild the circuit board via Matchless' writeup (adapted, of course).
The fact that blowerbike states your bike eats igniters also says "if you continue to use parts that will fail, your parts will continue to fail". So that is a warning sign that you really need a different solution, unless you want to continue to pay obscene prices for parts that are guaranteed to fail.
 
no dyna anything available....
no other options that i could find in the past 20 years except for an OEM part.
if one could be transplanted from anothe make or model that would be great and very useful to quite a few people.

FYI
the trigger plate/signal generator is very small on these models.
all other 4 cyl. GS's have the standard large plate set up.
if it wasn't for this reason a person could do a dyna S or retrofit a mechanical advance(earlier model) ignition system.
