Stator Checking

[RCAUTO]

I need some help in the directions for checking a stator, if good or not. (1972 50hp #50ESL72c) I use an auto range tester and was lead to believe that any reading between the yellow or yellow/gray leads and ground indicated that the stator was bad....BUT a shop manual I just read stated that an infinite reading during an ohm check of these leads meant it was ok and that the ohm between yellow & yellow/gray should be about 1.5, which it is. I could use some direction. It is an expensive part to buy if not needed...smile!

Re: Stator Checking

I think you are saying the same thing. There should be some measurable resistance (1.5 ohms?)across the stator coil, i.e. between yellow & yellow/gray but there should not be any connection between these wires and ground, i.e. infinite resistance between either of these wires and ground.

Re: Stator Checking

Well Im not sure what I mean. As I said I had heard that any reading at all between the yellow or yellow/gray and ground meant the stator was bad. The manual talks of infinite readings but that means there is a reading. It states: "Connect one meter lead to either yellow lead and the other meter lead to ground to check for shorts. An infinite reading in the HI ohms scale indicates the windings are good." What does infinite mean?

Re: Stator Checking

I think I have answered my own question by searching a bit more. An infinite reading means zero reading between the yellow or yellow/gray and ground. Any reading during this check means the stator is bad. Yes I was saying the same thing, Seasport. And THANK YOU !

Re: Stator Checking

I think you've got it. Just to be clear, an infinite reading is no reading, i.e. you'll get the same display on your digital meter as when the two leads are not touching anything. Depending on your meter this might read 0.L or perhaps just 1. A zero reading could be construed as being zero ohms when the meter will read 00.0 or similar.
