What's your favorite diagnostic tool?

[92integra]

Hey guys I'm wondering what your favorite or most used diagnostic tool is?! If we could leave out scan tools and multi meters that would be great consider in they a necessity. But if they are your favorite I suppose u better say so!

I really like my spark tester and and my fuel pressure gauge. Helps eliminate alot of problems with out diving in to far.

Picoscope

And my stethoscope forgot to mention that.

My computer with internet connection and downloadable shop manuals. Leak down tester is fun to use. Compression tester has saved me a bunch of $ with small engines and outboards.

Beyond the two you eliminated, I don't have a favorite. Fuel pressure and spark testers are important, early in a diagnosis. Vacuum tester/gauge is probably my most broadly useful.

25 years experience, common sense, and knowing the differance between restance and continuity.

Barring scan tools and mutimeters diagnosis in general would have to be my air-powered cooling system pressure tester... Strictly related to drivability tools, gotta say fuel pressure gauge.

Most of these tools are all required to diagnose properly. My favorite is probably the power probe 3. Cuts alot of diag time out of electrical diagnosis.

It'd be my Fluke 233. But if those aren't allowed, then I'll say it's a toss up between a Loadpro and a Fluke PV350.

With fuel injected car a noid light. Easy to check for spark without a tester and pressing a test valve can spray me with fuel to show some pressure. Noid light tells me all sensors are working good enough to fire an injector.

Power Probe is a great investment as well.

For common issues Google is your friend. When family or friends call with a car problem a quick online search tells me in 5 minutes what I am probably in for without even having to go look at the car.

Torque Pro app to my android phone. Cost $5.00. It's connected to my car's OBD II post via a Bluetooth adapter. It's a poor man's scan tool. It has saved me hundreds of dollars.

My modified Mac test light... Has a 24volt bulb in it besides that common sense

 

[DanInVA]

I am a big fan of the power probe. Paired with a good set of wiring diagrams, it is a big help

 

[Brownsfan]

By far my most used besides my DMM.

The best diagnostic tool is your brain. Everyone has one but only some learn to actually use it.

 

[mattygee]

The internet. Often taken for granted these days, but even professionals google symptoms to find probable fixes.

 

[PCMusicGuy]

My ears. Weird sounds around the cars are always the start of a new project.

 

[Ed ke6bnl]

I have to say my radiator pressure tester never sorry I retest after a job, have discovered leaks that I had no idea where present.

 

[SuzukiGS750EZ]

Digital multimeter with load pro leads

 

[dnschmidt]

Autel DS708
