As others before me have said, - really helpful video; if you happen to be working on a magneto, your video covers everything one might want to know; big thanks.
Thanks for this video, it's been helpful. One question how do you know if the coil is knackered? I'd guess it's a resistance measurement but what readings should I expect if that's what you do. Thanks
Hi, many thanks for your view and your comment. I've been told that a reading of OVER 4k Ohms (4000) from the high voltage terminal of the coil to either wire coming out of the coil, indicates that it is faulty. I hope this helps :-)
@@heritagemachinery thanks for your reply. That's good to know. I have replaced the condenser and had the magneto sitting on a radiator for a few weeks. I will try measuring the resistance. I need to clean up the points and give it a test but my Ruston and Hornsby PT sat half buried in a field for approximately 60 years. I don't hold out too much hope for the mag working. It's been three years of work to unseize the engine and get it all stripped down and cleaned up. It's ready to rebuild now and even has original paint!
Cheers for posting this. If the coil measures a few ohms or less between the wires but open from either wire to the HT contact point is it any good? Just trying to get a Bamfords EG1 up and running again.
The condenser helps to reduce the spark that is generated across the points when they open. If the condenser fails or is faulty then the points will wear out much quicker
Excellent video thanks for showing us how to take it apart for servicing

Thanks Bill 👍
I may have missed this bit of info but ALL magnetos must use wire core HT leads.
Found this really helpful ,Thank You
Thanks Stephen. I'm by no means an expert but it explains the basic strip down.

@@gillonstewart1601 Whatever the outcome, bravo to you for putting in the effort.
It sounds like you've done brilliantly so far!

Hello Sir please tell Is this RS rotor compatible with the SR1 rotor? In the video, the rotor shape is very similar to SR1.
Very nice description but you need far better lighting to show the internals as your working on it.
What does the condenser do?
The condenser helps to reduce the spark that is generated across the points when they open. If the condenser fails or is faulty then the points will wear out much quicker
Measure coil up and get generic chinese they make hundred of sizes resonably cheaply, done it on lot of engines for 1/4 of price.
slipryeel Thanks, I'll have a look. Anything to save a few quid.
slipryeel like where from? I’ve not found any
