OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Tech Talk Wipac Magister Condenser Discharge Ignition System

Hi again Plymouthbel, good thoughts there mate, but the trouble is we can't find one anywhere working or not working....there just not there to be had and I'm talking world wide.....anyone with one, would be attached to their restoration or perhaps stored in the shed...Mal's got 20 odd collectors looking for one for Jeffrey (blumbly) but, as yet, to no avail....
I don't know there would be a big market for them, apparently the were not that reliable....but it's a bit like the mascot on the radiator of a Rolls-Royce; just not the same if it is missing.

Hi all!
Great to see something different. Dad had one of these Scott Bonner engines in POP's old shed, I remember trying to start it but only got an occasional "bang / fluff" out of it. (probably just as well it was only held in the vice!!!) It went to land fill when he passed away.

Anyway I digress, has anyone checked out the National Library collection? I see they have Scott Bonner's from the 60's listed, i.e. brochures / catalogs (23pgs)Fly-mows etc.. Would be worth a look if someone lives close & photo copies some....

I do have a white Kirby tecumseh 2-Stroke air cowling with Scott Bonner on it, I can't help but wonder where / when & how that would fit in the Scott Bonner picture..

Hi All,

Just been having a look for some info on these coils. The only reference that I can find in publications is in a 1961 motorcycle magazine - there happens to be one for sale on eBay:

May be worth a look.

Cheers,

Hi Sir Chook, yes mate, I have seen that publication during my research....but without knowing if was the same unit as fitted to the SB Model 35 and 47...we are at a loss. Unfortunately we can't see the pages they refer to.

Well I can't seem to stop drooling over it.If you do decide that seeing her off is what you want to do.I'll be here holding my hand up high.So high you'll see it every time you walk out your front and back door.

I've attached a photo of a WIPAC Magister magneto "Condenser Discharge Unit". This example has a clear plastic back and reveals perhaps a coil and a condenser.
Regards,
Grant.

Thanks for posting that Grant. It gives us quite a bit more to work with. There may be two capacitors in there, including a very small yellow one standing on its end in the upper right quadrant of the picture.

I think the next thing we need (other than a look at the alleged printed article in the vintage motorcycle magazine) is a circuit diagram for the full system. We know that three wires connect to the Magister unit, but we don't yet know where the ends of them go, and I at least haven't seen a picture of the magneto unit under the flywheel.

Hi Grant, mate you are a legend!! I've wanted to see what was inside one of these for ages....Now all we need is a circuit diagram to see how it works and the component values and voltages!

At least we now know that the brass strap on the front of the Magister (missing in your pic) may be some type of switch?...it seems to go to earth...maybe some early type of kill switch.

The following pics are of Jeffrey's Model 35 coil assembly....you can see the 3 wires from the magister.


I wish we could get our hands on a schematic.

That's another step at least, Deejay. Can we have a look under the cover of the points box?

Yes grumpy....my thoughts exactly....Hoping Jeffrey chimes in here and posts some pics.

Due to popular demand I have got those pictures everybody asked for.Hoping that I can find one and put my 35 back on the restoring table.





As you will see it's just a set of points under there.It seems all a little confusing to me not sure why they just didn't put it all under there.

Good stuff Jeffrey, thanks for the pics mate...we may figure out how it all actually works now...

I don't know why they just didn't do a bigger coil and then put the rest under the plate.I know I know it's just to make it harder for when it comes to me restoring it.That's why they did it that way.The mongrels.

Hi All,

I have managed to get a copy of the article from the State Library today. I will scan the article tomorrow. Is it possible to upload PDF's to the forum?

Cheers,

Sir_Chook

The threads in the Manuals area are usually locked, and as far as I know PDFs cannot be loaded into other threads. I suggest you PM me and I will give you an email address, so you can send the PDF to me and I can upload it.

The answer to this question is yes you can....but there is a Mb limit....if the file is under 2MB you can upload it to a post, if the file is under that limit....Just use the "File Manager" in Post Options...Browse to the file; select it, and click "Add File"...wait till it loads....and then click "Done adding files" .....it will not preview, just click "Submit" and when the submitted post appears, there it will be.

This is the only diagram I have for the WIPAC Magister magneto.
Regards,
Grant.

I've attached some photos of a Scott Bonnar 155cc 2 stroke engine with the Magister magneto on a 20" Model 43 which I mow the front lawn with. The mower is from the 1960s.
Regards,
Grant.

Thanks for posting that Grant. It's the first time I've heard of a Magister ignition system that is actually in regular use. Nice mower restoration too. I don't recall ever seeing a Model 43 before.

Hi Grant, my thanks too for posting the pic...I have never laid eyes on one of these either....
It is of interest to note that this is the same engine and cowling as the Model 35 rotary; the only difference I can see is the air filter....they have even used the fuel tank strap up on the handles! This machine is also unusual in that it was only available in 20" cutting width and first released in 1960 and as a Model 43...was the forerunner of the ubiquitous Model 45.

Interesting also to note the this very large clutch and flywheel assembly on the 43 was not employed on the 45...SB reverted to the assembly found on the Model 33 also first released in 1960.
