I don’t use them. Too dangerous. In a world of pulse with modulation it’s a big no no. They have a place in the older simple circuit stuff. But full ground or 12v on a 5v circuit spells trouble. Also the probe is too fat and deforms anything you poke at it with

You have just pointed out one of the best features of using a scope instead of a meter. With a meter excessive resistance and a pwm of 33% look exactly the same on a meter. Then some kid grabs his power probe because they think all will start working correctly if they just put battery voltage at that terminal. Then all the smoke leaks out of the module.
I love my power probe. Everyone in the shop is afraid of it, but I use it all the time. I've never had it cause a module to fail. I have one of the older ones that just has a light and a sound, but the newer ones aren't much different than a volt meter. You can still do voltage drop as a calculation rather than a measurement which is often easier so you don't have to deal with 10ft long meter leads.
For the Guild competition they said you could bring your own multimeter. I thought about bringing my power probe just to fuck with them.
No way I would do that competition. Just seems like a lot of stress i don't need. This is not a competitive sport.
I didn't think it was bad. It was 3 sections. A 40 minute diagnosis task where the only tool you get is a Picoscope. A 30 minute 30 question multiple choice test off of memory, so no Topix. Lastly a 20 minute task where there was a partially built circuit on a bread board. You had to make the circuit work in a specific way using transistors. Once you got it to work, you had to take 4 measurements. I think a lot of people struggled with that one. I got lucky taking an educated guess as to how to get the circuit to work and got it on my second try. The guy next to me just gave up after like 5 minutes. I ended up being one of the winners and had a spectacular trip to Edinburgh with my wife for the reward trip, so well worth trying IMO.
Those things are extremely efficient in use. They're great to have around on the road and when you just want to get something done quickly.
You can do most things with a Power Probe, such as quickly find places that warrant more expansive capabilities.
Just don't send a bunch of juice to something that can't handle it. Avoid that, and you're cool. It's a great tool to have on hand.

Owned a DII of one kind or another since 02, one bad coil. 7 bad head gaskets. 3 altenators, a handful of starters.
No crank sensors? No oil pumps? No cam bearings? No liners? Man you got a good one
Well we ran down the whole relocate them if you wan't thing. I would have thought about fitting a York a/c comressor in that space. Ran the clutch off a remote switch and had an air compressor. Not sure a York compressor would fit, but something would. Now that's a modification I would want.
