'81 GS550T ignition replica for a few euro !

[Matchless]

all the information about the igniter replication is free to everyone
The program that i made the PCB is Sprint-Layout
http://www.abacom-online.de/uk/html/sprint-layout.html

Thanks a million! Thankfully I have Sprint layout and Splan. Could you supply us with copies of the .lay and the .spl files you used?

Have you road tested the ignitor yet?

Thanks again and excellent work!

I haven't tested it in real life because i must put the resin first to prevent the humidity to destroy the PCB

i have only the .lay file
you can download the .LAY file from the following link

Attention !!!

if you will try to make the igniter you must isolate the power transistor from the heatsink like the following pic...

Awesome stuff kokar... Your contribution is greatly appreciated!

 

[Matchless]

Kokar,
I noticed in the pictures that you used 2SD799 output transistors, but in your schematic and the parts list you still show the obsolete 2SD977.

Could you show how you connected up the LED's as that is a very good idea I think.

 

[kokar]

the original transistor is 2SD977 but this is obsolete there for i used the 2SD799
if you want you can use the 2SD1976 which include the high voltadge zenner

the schematic for the LED....

 

[Matchless]

Thanks man!

 

[kokar]

i change the high density crystal clear LED with normal LED because the ignition glowing like xmas tree......

 

[Adler]

Pete, i think now is right time for the Rectifier - regulator to be to replicated ..... :dancing:

Yes PLEASE! That's the kind of thing that could be very useful to me!

Excellent Kokar, fantastic work!

Apopleptic (and others) this is the same ignitor as used on all the '80 - '82 450's, the '80 and '81 250T's (I think that's right), and the same era 550's with mechanical advance I believe.

Pete these bikes use a different igniter than the 550 4-cyl. Different part numbers.
Checking the part numbers shows that this igniter only fits the 82 and 82 GS550 and the 81 and 82 GS650E models.

 

[kokar]

@Suzuki Don
different part number is because they have different connector than mine

if your signal generator has the coil face to face (180 degree ) and use 3 wires then i think my igniter is just right for you

 

[kokar]

i estimate that the following models is compatible with my igniter

Don, I did the reverse lookups on Alpha Sports and they all seemed to match, but the real key is in the pickup coils themselves.

If they run 60 - 80 ohms as the test resistance and have manual advance, then that ignitor is good to go

There are very big visual differences between the 60 - 80 ohm ones used on these models and the higher resistance ones used on all the others. I believe the rotor is also substantially different.

Ooops, missed this...

Kokar, will it be better than stock though? The stock R/R's tend to die even quicker than the ignitors...

 

[kokar]

Pete , the components for the R/R will be cost about 10 euro.....

 

[Guest]

Cool That's definitely a good price for a new R/R

 

[kokar]

not only new but also with better electronic parts

 

[Guest]

Even better!
