You piqued my curiosity boss???

So i ran a dry test

41 - R
26.6 - E
.216 - I

44 - R
25.9 - E
.213 - I

45 - R
25.8 - E
.217 - I

30 minutes dry running and the solenoid was very warm but i could bare hand it.

R - went up 04 ohms

Let it cool for 30 minutes and R was 42 ohms.

It was interesting to watch the results change but since this was a dry test it may be nearer to the OPs issue rather than your sceanario.

I think the next time i will pull the plunger and see what kind of amp draw i get?
