Home Made HEI Tester... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**PICKMUP** · 09-17-2009, 05:13 PM

After a day balancing on the radiator of my 79 dually with my feet/legs stuck straight up in the air, I decided I had to have a tester for HEIs. That's just too hard to do in the truck. Changed the module-nope...changed the rotor-nope...cap & coil-nope...complete HEI-yup!
Here's my answer to bench testing. Pics should tell the story.

That must be on of those new fancy POD ( power on demand ) kind of distributors. I see 8 spark plugs, and 8 plug wires, but only 6 little blue flames. DUDE what is up with that haha

How come they are all sparking at once? Shouldnt they alternate? Nice Idea

If the dizzy is being spun fast enough, it's possible that all 8 plugs fired while the shutter of the camera was taking the photo, especially the dark picture

I don't care what you say, thats just cool

monte0185 · 09-18-2009, 10:28 AM

My guess would be hes using a drill and an oil pump rod to spin it. Reason I guess that is cause thats what I use for mine that I made in shop class in high school. Handy thing to have around. When you have a dist thats questionable. Yours looks way better than mine though!!

Wow! Some would say "overkill" just to test a distributor since most of us just pull the plug wires and ground them... but I say inginuity.

68gmsee · 09-18-2009, 12:11 PM

Forgot to add... I bet some auto mechanic shop teacher would love to have it or borrow it as a teaching tool.

**PICKMUP** · 09-18-2009, 12:17 PM

You are all basically right...spin it by hand or drill, slow shutter made them all "show" in the pic, I used to just pull a plug wire & ground it, but too much "air time" dangling over the motor cured me.
I can now test all used ones before I install or sell them.
