motor dies after it gets to temp

Good numbers on the reluctor.

If the gap is .019" then that is waaaaay too wide. I should be .008" You can use 3 thicknesses of light copier paper to approximate .009-010". But be sure on the biz card stock thickness; you don't want to chase your tail on this. The right thing to use is brass shim stock from the hardware store. You're not supposed to use steel feeler gauges.
