a real challange?

Dad put my older brother on it and within about 10 minutes he showed me a peaking coil and said to change it. I smirked and told him it wasn't the problem because the resistance was the same as the others just like it in the circuit. He explained that it probably had a shorted turn which would have little to no effect on the resistance, but a shorted turn would essentially turn it from a coil to a resistor.

Well, he was right. That was my first experience in magnetics. That was a good lesson, one I never forgot.

Probably not the problem here, but just to point out that normal resistance on coils only proves there's no broken wire inside.

well those coils a pretty much unobtainium,
you would be lucky to find 1, let alone all 6.

and the resistance does seem to check out with what is shown on the 630ts service guide. :O
