Re: major distributor issues!!!
I dont understand if i'm getting wierd voltage while driving, how come it runs fine and than wont start. Is it burning out the coil and module? Wouldnt the truck die when running?

Re: major distributor issues!!!
How's your battery? does it die when your coil and module die? Just curious if it still has voltage to it after you kill your truck?

Re: major distributor issues!!!
It's a new battery and stays charged. Once i replaced coil and it started. Next time I relaced coil and no start. Replaced modula and started right up. Also, if I find wierd voltage while driving, what is the fix?

I would take it to a good mechanics shop to see what its doing. Get them to put it on the scope and get a waveform on it to see. It could be a capacitor it could be a lot of things. HEI can be real complicated at times. Its hard enough to do it with the correct equipment let alone without it. |

Re: major distributor issues!!!
How about the pick-up coil?
It's located under the centrifigal advance. You can test it without removing it... check in your service manual on how to check it. If it's bad, you have to pull the shaft out of the unit to replace it. They are a little spendy to replace. But, might be worth testing it just to rule it out. Gary

Re: major distributor issues!!!
Could you smack the top of the dissy with something, I know this wont solve anything but sounds like the same problem i had on a 69 truck that i had put an HEI in and after replacing things time and time again, for some reason i smacked the top of it dissy and it started right up. So i told my daughter when it wont start to smack the top of the dist. Never did find the problem we finally sold that one. but it did it a couple of times a week.

Re: major distributor issues!!!
I replaced the ignition module and it started right up. Now how do I check voltage while driving? Do I crimp another wire at the distributor connection or can I just check it at the fuse panel since thats where the wire comes from ?

Re: major distributor issues!!!
Just use alligator clips and clip on as close to the HEI as possible. Duct tape the voltmeter to the windshield where you, or better yet a friend, can see it.
Ok, if your wire from the fuse panel is at least 12ga you can check it at the fuse panel. Drive it with all accessories on and do some stop and go and some at speed. The volts should never vary more than half a volt, even when you shut the accessories off at speed, there should be no spike. Should be 13.8 to 14.3. Don't trust your memory here, write it down.
