he sees you using a test light to do a quick diagnostic check on a Duraspark system and fire the coil with it..... Priceless.
Got his attention after that ! Scope even came out to show him how to do power and grounds and magnetic pick up tests. Just to teach him that module is only replaced if everything else is good. Too bad the scope can't be used to check resistance. He was almost disappointed when I pulled the DVOM out for that.  ;D

Showed him the wire loop soldering iron test yet?   :-?

If I have a channel on voltage and another on current....

Then I have a maths channel dividing the voltage by the current......???????

Nope but I did get one of the young ones with the engraver as a soldering gun.  ;D

That's what I was thinking. Not saying there's not a time and place for a resistance reading, but having voltage and current is a nice dynamic picture of resistance.

Hello Tom!
Please explain the "Wire loop soldering iron test" please. Is it using your soldering gun near a magnetic ick up the induce a voltage in said pick up (VR style cam and crank sensors WSS on ABS, etc)?

Exactly.   ;)

My favorite was when I had an 80s Mercedes with a weak coil. We didn’t have a replacement. I asked “ does anyone have an ignition coil ?”

A coworker hands me a Honda distributor with coil...

Boss says that’s never gonna work, it’s a different coil.

I says” a coil is a coil, is a coil....

It starts right up

I thought that too, but I had a 1929 REO with a dead coil, so I borrowed a coil out of a 1926 Nash. Didn't work. The difference? Positive ground on the Nash and negative ground on the REO.

Ok, you got me there, but i only work on vehicles with negative ground ;D
