71 Dauntless Ignition Cuts Out After 20 Minutes

Replaced switch, no spark. Replaced coil, no spark

 

Make sure you have continuity on all wires and if so, condenser next

 

Is there any way to test the condenser without replacing? Not sure anyone has a local one for a prestolite

 

Condenser is a capacitor. I don't know how to test. Look what i found.
what exactly does the condenser do? - Yesterday's Tractors

 

Yes, of course lol.
OK, sanded points, did nothing. Where the rotor contacts the distributor cap was dirty, I sanded it and jeep started right up. That seem possible?

 

Oh for sure! I don't have time for a couple hours or so. I did sand the points a little and it does run worse. Idles good but breaks up when revving it. I measured dwell and its at 22-24 degrees and the sticker under my hood says it should be 30. Would that make a difference?

 

Yep

 

Order all new ignition parts and set all of it correctly. I bet your issues will disssapear.

 

After sanding points (lightly) it is important to wipe them clean of any particles, such as swiping a clean piece of card or paper between them.

 

Cleaned them off and now it runs great!!

 

HEI

 

Yeah, well, I learned it the hard way! But I'll never forget.

 

So, I think originally I was running out of gas(and having carb issues period) and had a faulty ignition switch. Today, I seriously went back and forth on a road 1/4 mile long for about an hour.. Longest I shut it off was a couple minutes.
I took her on a public roadway and let her rip after she ran for an hour and a 15 minute cruise and I didn't get stranded! My odometer is off due to tire size so I'd say 25-30 total miles I put on total with well over an hour run time.
I do believe I either have some water in the carb or need to rebuild it. I'm ordering some stuff from rockauto and I'll order me up a carb kit as well.
Thank you guys for the absolutely amazing amount of help!
