You clearly are an advanced user..... but you need to use the "sense LOCK " button ; you focus in on the probed or problem wire then lock that signal to the transmitter; any of the other wires will not interfere with the signal so long as you "calibrate" the signal from the very start. One push of the lock button at the start and it will only follow the probed or monitored wire.
Is there an advantage to checking relays like this as opposed to pulling them, applying power and ground to the control/coil side with a power probe, and checking the resistance of the load side with a meter? I can see the usefulness of this method to check voltage drop in general/other cases, but didn't know if it was better for checking the load side of relays specifically for some reasons I might not be aware of. Thanks.
This way is more effective. This way you are confirming coil control and circuit integrity ( and load resistance with a little math) . Testing in the system is usually more preferable. I'm not sure if you are referring to the resistance of the actual load or the resistance of the coil ( that's also a load ) If you are referring to the switched load you can actually use ohms law to figure out the resistance since you have voltage and current. GREAT VIDEO Mark
Just saw you were referring to the resistance of the contacts on the load side of the relay . The way demonstrated in the video still works to get the resistance as you can use Ohms law . R + E ( voltage dropped ) / Current. Sometimes problematic contacts and connections will not fail without current flow.
I wonder if you crank up the speed could you tell which noise was generated first. I assume the vibration that propagates through the suspension is fast. but is it measurable? also do you have a link to those test leads?
Thanks good advice. The microphones are from the steelman microphone set with that box with the dial that has 6 microphones hole and a headphone Jack. I just used the microphones. I got 4 bnc to female 3.5 mm audio Jack adapters from DTECH ENGINEERING. who make great video btw.
Very cool case study. Nicely solved. Do you think it acted up in reverse, but not drive because the harness would press against the firewall grounding the compromised wires when in reverse? Then, in drive the harness would move away from the firewall(moving the compromised wires away from ground) allowing the system to return to normal until the vehicle was put in reverse again?
the load pro is a GIMMICK just use a car head light bulb they are for free and you can get different amps i use a 3 amp 5 amp bulb for all my load lest. do not buy that junk
I'm going to purchase this product thanks for the video. If I need to trace a wire back to the computer PCM do I have to disconnect it from the PCM so it doesn't cause problems?
Yes everyone gets this thing and think it dosent work but in reality they don’t know how to use it. This is huge for the people that thought it dosent work power probe should pay you for this because a shit ton of people send these back because they think they don’t work.
Dude, you just saved me a S*%t ton of time and frustration!!! I'm about to dig into a couple electrical nightmares, and the knowledge I gained watching your video will serve me well, this I know! Thanks for the video!!!
I’m not very experienced with scoping but let’s say you also scoped the crank sensor buttt did have a bad cam sensor? Would doing an in cylinder capture have caught the issue? Thanks for sharing.
i think you would have to input the signal one wire at a time but he is not explaining it that way. In other words you desensitize one wire and trace it, then if you don't find the break in that wire you go to the next wire and input the signal and trace that wire, and on and on.
...um....raise your hand if you were following him well up until the last 3/4 of the vid then just suddenly got lost on his explanation and the visuals there...w.t.h.?... ...hunh?? I'm getting an {F} on my test. lol!😅
I own this and never understood how it worked. The instructions suck, this is the best display of how you find A broken wire! This has given me a new outlook for my job. Rodent damage is commonplace (washer pumps hitch harnesses etc)
