I sometimes use a magneto for testing ringers.

Larry

Can you explain how to do that?

Just hook the magneto to ring and tip on the phone and crank away!

I think I should mount a magneto to the corner of my work bench so its always their. My magneto has 3 screw points does it matter which to ring and which to tip?

Sorry: Due to a change of regulations at Canada Post requiring these to go out minimum Small Packet at $7.80 each, I will no longer be selling them. I shipped one today and it will be the last one. Alas, I was earning only 50ยข each on them after my cost to get them here.

Before I could send one including purchase price for than that total. It shipped in a rolled up envelope 10 inches long x 4 inches wide and a half inch thick, with one unit weighing 100 grams, and shipped for $2.20. However, now only stationery (paper) items may be shipped letter-mail. Argggh! At least I was able to help out some people before Canada Post's increase made it impractical. A $5.60 increase in postal charge!

Pissed off at my former employer!

Order them now from http://www.ebay.com/usr/arihavelectronics :

I do have 9 units here which I will sell to those visiting the museum at my cost - it is just that the shipping now costs too much to make it practical to ship them. For the mean time, it will be cheaper to order them from the new links above.

Ring and tip doesn't matter in this case.
With 3 terminals, the magneto probably contains some kind of switch operated when cranking.
It might be at least 2 versions of this so just try, The 2 terminals giving ring current when cranking are the right connections.

Tried to make a sketch of circuit for testing purpose.
The upper circuit are probably the most common solution, and are suitable for connecting to a telephone line too. This will not send current to the exchange, only to the ringer/telephone.

the other circuit will work too, but shorts the line when cranking.
