Weird electrical (igntion?) issue

Seeming the trucks all use the same type of spark trigger in the distributors I'll say you'll be safe with the Summit unit. Nothing on eBay?

I checked all the local parts stores (hoping to get my MM on the road ASAP) for the Beck/Arnley, nobody had it in Albuquerque.. Advanced Auto did have a cross-referenced mathching Borg-Warner, part # ru500 @ their local warehouse. I'll pick it up at 10am, hopefully it will do the trick.

the resistor should be 0.8 to 1.2 ohms resistance for the ballast resistor.

Thanks, good information. None of the ones I listed above had their ohm rating in item's specs on any of the sites I checked. Only manufacturer that had a tech 800 ph # was wells. Had I known this this morning, probably would have gone for a Wells part because I've had good luck with some of their other parts.

Anyway, thing I'll be ok with this Borg-Warner. I'll post in a few days with some results after a little driving.

And Geezer, just wanted to say I found several good articles describing #1 symptom of a failed resistor is symptom I described in my first post. I've wrenched a fair amount over the years, but was completely unfamiliar with this part and it's function. So I think you nailed it... Thank you very much.
