Sun Armature Tester (AT)


This Sun Armature Tester model (AT) was found as a non-working hulk on e-Bay. It took some time to refurbish and test, but it came out looking great. There things are real “cool” to use, and actually make a shorted armature “growl” when inducing a magnetic field in the windings. Not much used anymore, but for old cars this thing is a great diagnostic tool.
