- Test Light - regular vs logic probe.This is a video that i made to show a few different types of test lights. First up is the regular test light with a probe on one end and one connector on the other end. Next is the smart test light with a probe on one end and two connectors on the other end. Both test lights are around 20 dollars or so . Hope u find this video helpful.
One of the few videos that explained that you can take a traditional circuit tester and check for grounds/hots by switching the connection. Thank you!
Thanks for stopping by
Great explanation. Thanks for sharing!
Glad you enjoyed it!
thanks for watching
excellent teaching!! Thank you!
Thank you. You have very good videos yourself.
Great video I bought one of those at Harbor Fright and it had no instructions whatsoever know I know how to use it. Thanks
good job Terry
Cool. Thanks for watching
Thanks for the Tutorial!
@TimsComputerRepair yea just a little thanks
@PcTechFreddie I will take a little look and see what i can do
Oh we have some production in this video...SWEET!!! Good job Terry
Do not use a regular testlight on new cars. they draw too much current in the circuit and can fry computer control modules. A logic probe is computer safe because an LED draws almost no current, like 7 milli-amps or something. to prove my point hook one up and put the probe on your upper rubber radiator hose i bet it lights green for ground.
This Logic Probe isn't safe sorry. It will still do computer damage. They are like $12.... dont fall for the trap
Yes you are correct. I have seen computers fried cause of old test lights. But there are still a few places they still work better on.But some kind of scope to see the wave pattern is good for testing newer cars. Thanks for watching
@Britec09 Thank you Sir
Nice Video.
@PcTechFreddie thank you
So many people saying text lights burn out computers. Test lights don't kill computers shade-tree mechanics do. You have no business probing a wire unless you know its function and/or what it's connected to.
I have the same 48 F6 and my 50 F1 that is a driver.
Cool , Thanks for watching and commenting
@mitchman5155 Thank you
Thanks

It's not ok
you dont need both just yous the ground clip only if the battery is too fare for the smart test light

You can use a test light on modern cars you just have to know what your doing.
Go watch any number of Scannerdanner videos for illustration. Thumbs down on this vid though as poking holes in wires is a VERY BAD idea. Guarantees trouble down the road. A test light that lights by itself is of little use. It doesn't tell you if the circuit can handle a load or not. Get a Loadpro and DVOM and learn a much more effective way to test circuit integrity.
I do have a load pro , but it has a different use than a test light. This video was mostly showing the difference in test lights and not a back probing how to. Sorry if you mistook this for a test light manual video..
moomike laloo ; be advised however that may circuits run through a body control module if the not the PCM itself. On the most modern cars , I believe everything will run through either . Have heard that people that have made incorrect connections while installing after market led lights have caused problems with a BCM or a PCM . Can't speak for the quality of the led light but we need to use computer safe on all circuits ( except alternator or starter , and other high amp circuit ) , especially modern . A good computer safe test light will check up,to at least 24 volts .
Case in point , the test light will light even if you have a battery cable with ONLY one strand of copper left . You can read continuity and 12 volts all day . But it will NOT carry the current load ( amps ) when the circuit is operating . Any high resistance ( corrosion ) will stop current flow . You can read a " connection " but you won't get the amps . Voltage drop testing is the way to check it - with the circuit OPERATING .
