OutdoorKing Repair Forum Forums Finding and Swapping Wanted Victa Powertorque ignition coil wanted to buy.

Hi Everyone at ODK,
I am looking to purchase a used Powertorque ignition coil with attached module, in working order. I am happy to pay up to $30 for one, and will cover reasonable postage to Beecroft, Sydney.

Hi two stroker,
you've just exposed a flaw with the later coil with inbuilt module. As the module is what usually fails, and not the coils on Powertorque engines, having it like that forces you to replace the lot instead of the cheaper and readily available separate module.
Must have been designed to simplify production.
One disadvantage of the later Chinese made engine castings over the Australian ones.
I wonder if there's a way to bypass the dead module and and fit a different one?

Hi Mowerfreak,
In relation to the ignition units that contain the module and coil as a single unit, rather than the earlier two piece setup, I was wondering exactly the same thing.
Could I pull the plastic covering off and affix a new module to the wiring of the coil?
It would be theoretically possible, but depending on how it’s been constructed will determine the feasibility in a practical sense.
As you say, the change was most likely economic in nature. I much prefer the setup with the coil and module wired separately. So much easier to deal with.

G-day twostroker.

There is an upside to the combined setup. It delivers a more powerful spark which leads to more consistent starting I imagine.

You have nothing to lose pulling your old coil apart to see for yourself how feasible it is to graft a standalone module to it.

Otherwise, surely you can find a dead later type PT to scavenge one off, or even replace the whole engine with another one?

Hi twostroker and MF,
I'd check local tip shop or metal recycler for old powertorque mowers..... might get a few good parts, coils carbs.....who knows. cheers
I saw a couple of PT 40km north of me for free, pretty junky, but I'm too bust at the moment.. But they are everywhere.
speedy

Unfortunately people who grab them are even more prolific. Both times I found a Victa PT recently, it was only seconds before someone else stopped to grab them too.

Thanks Guys for all the information and suggestions.
I too have noticed that ( in Sydney I refer to only) it’s becoming increasingly difficult to locate the old mowers like I used to be able to. Seems like the only way to acquire them now, and I mean the real wrecks that used to exist on the kerb, is to pay for them.
E bay/gumtree-$30-$40, so I did that and parted an old commando and another one out. Coils and module were perfect, resistance on module and coil both low, in the order of 6-7 k ohms.

The other area I would ask others of, is does anyone ever bother dealing with the surface rust that builds up on the soft iron E core? I usually sand if bad, apply the usual phosphoric acid, then black enamel. Any one else do this to help them survive? Techniques???

Hi twostroker,

Please post photo of the ignition coil. I may have one.

Hi Carbymaster
Thanks for your interest.
Here is a photo
It’s the Powertorque coil with the module built into it- not with the coil and module being separate units, but either will be fine.
Best wishes

I decided to drive home by a different route the other night and came across this.

Did you end up getting one? I'm in the same boat

Hi Kev,
I have plenty here

Hi all,

Just digging up this old thread.... I am in the same boat. I need to replace my coil MA005599A. Anyone have one or know where I can get one ? I have PM'd NormK already

Hi Davemal,

Here is a coil with images showing it CLICK HERE but note that you have an extra '0' quoted in your part number it should be MA05599A which includes the 'E' plate for the coil.

It should work but check the images on the site.

Another option is buying a complete mower on Facebook marketplace they are around $30. and Gumtree around $50.
but they don't sell quickly these days so you can always offer the seller less or look for a local tip shop or scrap metal yard.

Some people advertise the mowers for free as they just want them gone.

Cheers
Max.

Postage is the killer here.

thanks all, Yes I am looking on kerbs and will get to the tip when I get a chance...

Going by https://www.outdoorking-forum.com.a...ta-coil-ma05556a-ma05599a.html#Post78270 - it seems that the MA05556A will not work...

As I said PT coils very rarely fail because being down low on the motor they are kept cool by the fan

Just as an update, I have reinstalled the coil and there is no spark. When I can get a helper I will test some more with a spark cable tester just in case its a bad cable or connection somewhere. Oh and I will also remove the wires to the carbie to rule out those causing havoc.

I have been keeping an eye out on gumtree and will go to the tip when I get a chance to maybe find a donor motor. I will give it another few weeks and if no joy, its off to the tip ( or perhaps for parts on gumtree). Its had little use and has electric start, so its a shame really.

Have you moved the screw in the plug cap, that sometimes can kill the spark

I too have a 2011 Victa Mustang VEX160 2 stroke, which has in the last 3 weeks decided to lie down and die. No spark. I removed the ignition coil (MA05697AZ with built in module) after some troubleshooting and took to the local mower shop, where they tested the coil and reported that indeed it was dead. My multi-metering found resistance around 14k ohms.
My neighbour volunteered a coil with separate module (MA05556A), which has resistance around 6k ohms. It will physically fit in place. Bolt holes match. I plan to install and give it a go.
My question: Can the module be mounted on the sheet metal cover below the crankcase air box, perhaps temporarily for trial, or must it be mounted outside/inside the lower crankcase housing. This will necessitate drilling and tapping two small holes in the casting.
I'll attach a couple of photos of original coil and temporary replacement. Still like to get hold of a coil with built in module, as in agreement with a comment above, the mower has been an excellent starter. First pull every time!

Hi JamesS ,

The coil core has a good earth to the engine block so with the module it's best to earth that to the engine block as well ,
you can put the module somewhere else as long as it has a good earth back to the motor but the easiest place to install
the module is near the underside of the carby ,a pop rivet to hold the module on or you could use a threaded small bolt
with a lock nut but then the engine will need to be removed to tighten the nut or you can tap a thread in the cast iron.


Cheers

Durrr! I should have thought of that! It was pop riveted on the old engine block I got it from. I thought of riveting it to the air baffle plate which is sandwiched between the engine block and the mower deck. I was just trying to avoid modifying the engine block.
I imagine I'll have to drill a couple of holes anyhow. Pop rivet won't let go for sure!
I'm hoping it will solve the starting/running problem. I don't want to junk it. It's been a good mower until now. Best I've ever owned.
Thanks for your help Max.

Cheers,
James.

I'd avoid putting the module on the inside/on the baffle plate as there is so much grass and dirt / dust that the fan sucks in ,the coil
has to be in there but best to mount the module on the outside casting it can also still get a lot of grass around the module on the outside but is easily cleaned away with an air compressor and air gun when it's under the carby.

Cheers
Max.
