WaaLaa, talked to company I bought dist from, they are sending me a module I don't need. Put vac gauge on, no drop in vac before it died. Coil seamed a little warm. So I put coil in cup of ice on intake manifold, ran, and ran, and ran, and ran till I shut off, Restarted ran, ran, ran. After all the conflicting info from coil mfg's on ballast resistors, accel said under 1.0 ohms ballast, over no. This coil is 1.5, I checked it myself, although not hot. So the first thing I replaced, is still bad, although worse than original, until that one was over 1 year old it would only do this after driving a long time when it was hot outside. I guess I'll put a ballast resistor on coil only, until such time as I can find a good coil, made in the USA.................
