bought a like new snap on growler at auction. I think I know how it works, but don't know what the meter is for. if the blade sticks to the arm. does that mean it's shot?

With the armature in the V jaws of the growler hold a strip of steel( hacksaw blade) on top and inline with the armature. Rotate the armature while holding the blade on top. If you find a spot where the blade viberates wildly, you have a shorted winding. Clean the slots between comutator segments as a build up of brush/commutator copper can cause a false short reading.
Mine does not have a meter, only a test light. To use the light you touch one probe to the armature frame , and use the other to touch each comutator bar. If any light the light, that bar/winding is shorted to ground.

Hi W.W., There should be a set of leads with the machine. Touching these leads to the commutator will give you a meter reading of the output being induced in each segment of the armature. Since you are not familiar with the machine I suggest you just mail it to me? But if you decide not to do that, I'm pretty sure Snap-On could get you a manual. Good luck...Al English

Hi Dick a growler is a test Instrument used for testing the comutators in DC motors ie: starters
and I think also generators. It checks the integrity of the windings.

A growler is a loaf-of-bread size bench tool that every shop used to have when it was more profitable to rebuild starters and generators than put in replacements. Twenty years ago, every garage mechanic could test the armature while rebuilding the starters and generators. The continuity light/ test leads, could also check the continuity in the windings in the field. The field being the windings inside the steel housing. Like was said, the growl came when a bad winding caused the steel strip/ie. hacksaw blade to bounce and growl. Would like to have one of these along with the small armature lathe, if I ever find one on auction. John Ne.
