I know this stuff is old hat to most of you on here so can you enlighten me as to why I am not seeing a mirror image of the 2 signals. At least that is what I have read. Thanks

Maybe you are tasting the same wire by default.
These wires are usually sitting next to each other in a connector and our probe will look as if we a aiming for A and B but in reality we go A only.

Or Motor Bikes are completely different than cars Undecided

My eyes are not what they used to be...even with glasses, lol, but In my defence I had my 2 younger techs check as well. Guess what, maybe they need glasses. It is very tiny and cramped so I guess it must have been on enough of an angle. Live and learn.

Probe had snuck thru and touch the Can H wire so it was the same signal. My inexperience on Can bus shows but smarter now. lol

Hi James. No worries, don't be embarrassed and Mick was just showing his experience as you have now gained.

I happen to have one doing it and the probes are connected properly. Go figure... Cool

Thanks for the reply! Hope all is good in your world.
