ISC Question

[BaddAssGst]

I just bought a brand new idle speed control motor, like maybe 5 months ago and used it on my old Eclipse. It was good when I got it and when I ended up selling it, I pulled it off and put another used one that was good on. This thing was used for maybe 2 months and was pulled off and sat in its original box. I just pulled it out and decided to check it and I was getting 37-38 ohms of resistance which is, obviously, not in spec (28-33).

What is the likeliness that it should've failed in that time? Especially not being used? Especially all of the coils going bad?

The newer ones look different and the coils have different resistance. Id guess that's what you have and it's fine.

I knew you'd be first to answer.

That's almost what I figured although I can't figure out why I had in-spec resistance when I first tested it. It is the "newer" ISC though, with the black casing.

I'll test it out when I put the motor back in this weekend and be back for results. I just kind of thought that was strange.

Maybe it was warmer the first time.

The key thing we're are looking for is that the resistance isn't so low that the current spec for the drives is exceeded or so high that no magnetic field is created and it doesn't step.

So it's a good possibility that the ISC motor is still good, with just a few more ohms of resistance? I'll definitely keep this thread up to date after Saturday.

Thanks Steve.
