Growler DC Generator Starter Armature Testing 

Yes. From my observations, lack of attraction of the hack saw blade to the armature indicates no internal shorts. Of course, you would still want to check for shorts from any commutator segment to ground.

If the armature windings were shorted to the armature, then yes, an ohmmeter would tell you that. But, unless you have an expensive MilliOhm Ohmmeter, you probably can't tell if a couple of windings are shorted to EACHOTHER. If you check the resistance of your ohmmeter by shorting its leads together, and it reads more thatn 0.00 ohms, then NO. Note: I will accept arguments to the contrary, but I think that's why the growler was developed in the first place.

Technically, yes, I guess. But the resistance of short pieces of heavy copper wire is very small, requiring an excellent low-ohms meter. 10 feet of 12 gauge wire has a resistance of only 0.016 ohms.

Sorry, but I can't help you there. I did google "generator armature what is a core loss test?" and got lots of interesting hits.

I just googled "Growler type armature tester" and got 3 hits from Ebay, with prices ranging from $50 to $170.

Hello Junajo. No se habla Espanol. Here is what i think you asked: What are you checking? the currents induced in the reels (coils?) of the rotor for detecting short effect (circuit) eddies (eddy currents?) If this IS your question, I don't know A lot more current flows through shorted coils, heating up the armature. Since we are using 60 HZ to power the growler, which is essentially a transformer primary, there must be some eddy currents produced as we add that armature and its coils which act as a transformer secondary. Maybe it's the shorted turns that reduce the eddy currents allowing more current to flow than would happen with a normal armature.. I think there's an opportunity here to add an AC ammeter into the primary circuit to see what actually happens. I think some growlers do have such a meter. Pete Stanaitis ----------------------

Hello, Ghanshyam singh yadav. The best translation to english is: "where to get head?" If you mean to ask "where can a person find a "growler", then here is my answer: Here in the USA we find them in used automotive test equipment auctions from time to time. There is one for sale on Ebay right now: www.ebay.com/i/142514188926?chn=ps&dispItem=1 Many people from India look at this video, so I think they must be available in your country. Go to an automotive trade school and ask the instructors if they know where one might be found.
