[James] Looks like you have the beginnings of a distributor rebuilding business yourself.	Is there any parts support for that Sun machine. 


Cecil Bearden AT list member, Oklahoma farmer, and Professional Engineer <crbearden at copper.net>;That is my method of testing coils.  I usually take the distributor out to install points and set them on the Sun Machine.  Probably 9 times out of 10, I end up rebuilding the distributor.  I quit buying rebuilt distributors, they are just crap....  With Industrial engines, there are not many rebuilders around...  This is where my lather and mill pay off big time..

Gilbert Schwartz AT List member and Allis Chalmers G owner <vschwartz1 at comcast.net>;I would like to try and delve into the wide knowledge and expertise of the members within ATIS. 
Is there any acceptable method of determining if an ignition coil is good short of installing it on a running engine. Our 1949 AC G would not start a few days ago after being parked for a short period of time. A quick observation determined the contact points were beyond use. I went to the local auto parts store and was advised I probably should replace both the points and of the condenser because they felt like that condenser went first and it caused the points to burn up. With this information I also purchased a new coil even though I wondered if the coil was a bad. 
Bottom line; Is there any way to bench test a coil? We have several used coils laying around here of questionable viability. I would like to pitch them if they aren't any good. 
I appreciate anything you can tell me.
