I guess I'd not thought about there being ranches in eastern Oregon. Maybe I'd better do more traveling!

Eastern oregon is a high Desert climate where cattle out number people by quite a bit. My county is over 10,000 square miles with a population of around 7100. Most people think of oregon as forested, but the east side is sage brush/juniper/desert

So, did some more testing today. Checked vacuum devices. Apparently my brake booster leaks, but when plugged off makes no difference in my current running condition. Everything else tested out fine. So, onto electrical components... coil- good, wiring between distributior and module- good, stator- when I could actually get it to read anything at all it measured 219 ohms... but it read open alot of the time. It's supposed to measure 400-800 ohms. So I assume this is my problem. We will see, either way this part needs replaced!

If the brake booster leaks, it will cause a "hissing sound" in the cab when the brake pedal is applied. Mine does it everyday . Let off the brake and it lessens....apply the brake and it increases It's the Booster.

Reminds me of Utah.

Yes, I've just been to Nicaragua for a couple of weeks. But, obviously there are places in the US of A that I don't know about. ROAD TRIP!

Yes, I will need to address the brake booster... however, as if right now, I have it capped off at the manifold and it make no difference in how it's running. My wiring from the module is a mess, I tested it and continuity is good from connector to connector- I will be picking up a new harness from the junkyard on monday or tues... it would be dumb to conine to use this harness- under the factory tape the wire insulation is coming appart. With the stator testing bad I will be replacing it as well. Hopefully it will fix my issues.

I took the distributor out and tested it on the bench. So, when I have my ohm meter hooked up it reads it as a open circuit. However when I rotate the shaft it will read resistance as the reluctors pass the stator- but sometimes they won't read at all and sometimes it will show around 200 ohms (out of spec). So, it appears as if the stator is only sensing the reluctors sometimes and not always... and when it does the value is under spec.

Yes, the vac hose will be addressed for sure. I won't drive it with the booster disconnected. For now while I'm narrowing down problems I will keep the vacuum port plugged so I can eliminate that as a problem.

So, just curious, but is the ballast resistor an actual resistor or is it a resistor wire?

It is a piece of wire in the harness.
