G'day everyone,
I ended up changing out the points and condensor last night, I have checked the points that I removed and also the condensor with a multimeter.
The contact points seem to be making a good contact and were probably still fine after I gave them a clean, but anyway because I had a new set I changed them out.
I also tested the condensor (capacitor) on my meter and it also seems fine and was probably still ok to use but as I had a spare I just changed it anyway. I also checked the kill switch on the carby lever, and it also worked fine and was not shorting out.
Now here's the funny thing and I am kicking myself a bit. When I replaced these with new parts it still didn't seem to have a spark, now I am thinking maybe the coil is gone or there is something wrong with the spark plug lead that runs from the coil to the spark plug. I checked the screw at the end of the lead which is inside the spark plug boot and it's very clean and didn't look rusted at all. So anyway I removed the screw and noticed inside the wire looked a little corroded. So I put the screw back in again and screwed it in the wire more to try and make a good contact. Bingo I now have spark! Damn and I even remember NormK mentioning this a few weeks ago when he didn't have spark on his mower, but because I knew this mower used to run and the screw/wire looked clean on the outside I assumed the connection was fine! Damn well you know what i'll be checking first now on any mower I find that doesn't have a spark! LOL!
I looked at the schematic diagram you have there Thecarbymaster, the problem is these days you can buy a ready made module for $20 on ebay shipped to your door.
Yes the original Victa modules and even the aftermarket one's available probably have similar circuits inside to the diagram you have shown on here.
But I think by the time you are to buy the parts and construct the circuit yourself, it's probably cheaper and easier to just buy a ready made unit.
Cheers!
