Killed Two Distributors and Don't Know Why!

"Take first one", here highlighted below... first one what?:

If not, unhook distributor. Take first one, then the other pickup clip leads, and "tap tap" ground them at the battery connection. Coil should make 1 spark each time you do so.

If not, try another coil. If that does not fix it replace the ECU

Also what is "AFU" ? All F'ed Up? lol?

IF you hook it all up and it WORKS, then there is something AFU in the car harness. SUSPECT a bad ECU connector OR a bad DISTRIBUTOR connector

One more thing is what ever did this killed two distributors... why would a bad coil kill a distributor, or why would a bad ECU kill a dist? I can see the Ballast killing it if it were bad and over volted the dist. Do you think that it is the most likely part that is bad? Plus I replaced the ballast, coil and the ECU before I put the second dist in. Why would it do the same thing? I did use old parts, but it just seems strange that the same thing would happen.

Thanks a mil...

Poorly worded. Disconnect distributor connector. Take the engine harness end, not the distributor end, and tap the bare connector pin to ground

If not, unhook distributor. Take first one, then the other pickup clip leads, and "tap tap" ground them at the battery connection. Coil should make 1 spark each time you do so.

It might be that you did not actually "kill" a distributor. Either there is some problem with the system leading you down the wrong road, or the distributors are "right on the edge" of being able to trigger the ECU (check condition of pickup/ reluctor and reluctor gap) or you just plain got "lucky" and two of them failed.

I've never heard of this but "I guess" it is possible that a problem in the module might put DC current on the distributor connections and burn it up. The problelm is I have no reference for this.
