Hi everyone here is another case study I did using the Escope Elite to find a electrical noise issue on a remote throttle sensor circuit. Escope HD for the win.
Nice case study. This is the reason why it is so important for those using a scope to check known good circuits. Currently many of the new scope users in my area get caught up with noise on signals of all sorts, IE spikes on crank or cam signals. Some noise in normal but learning how much is too much is where experience will help. Can you reply or put in your description briefly the specs that…
Great video Mikey! ATS scope looks pretty sharp
Scope? What's that? 😂 Just kidding Mike. Don't hurt me!
Michael, a scope makes it easier to catch such issues, indeed. Do you have a guess about what went wrong with the original wiring?
I am thinking the twisted pair wires got damaged in one section close to the engine.
Now you got me wondering if that would show on a lowly ohmmeter or not...
I dont think so. A ohmeter can tell if you have continuity or a short to ground or wire to wire short but it can't tell you if the twisted pair has unwound too much.
Ah, so you are saying it is not physical damage to each wire... I would love to see a picture of such damage.
Sorry I dont have a pic. I just ran a new harness to the remote throttle. I could not see anything obvious.
Michael, yeah, I understand that there is no picture this time, but if sometime in the future you encounter a twisted pair that passes the ohmmeter test and has an unwound section, that would make an epic picture. Thank you in advance!
So how do like ats scope ???? Could you have found this with a pico
The Escope is a very capable tool Randy. I have fixed tons of problem buses with this scope. Plus I like the fact that the equipment is designed by a Tech and Engineer and it has handy features designed for the Tech in mind. Bernie, Neil, Jeff are also very open to suggestions to make the equipment better as well. Now as for Pico being able to find this fault yes absolutely it would see it. I am…
So two different scopes are better than one
Do you mean dual time base on the Ats scopes?
Thanks, good report. We have a saying in tech circles in uk. No scope, no hope. Regards steve.
I like that Steve, no scope, no hope! Not too far away from you in Dublin...Hope things are picking up for you garage wise, lockdown is getting old.
