Thanks buddy

[@bigcat1067]

Thank you very much for using basic tools . I find myself limited to these but hopefully soon a simple oscilloscope

[@DallasAutoDiag]

Which oscilloscope are you planning to buy?

When you talk about 3 phase motors I am thinking that you could measure ac voltage between any 2 of the phase wires and frequency would give an indication of the speed. My reference is from variable speed inverter drive motors that are used in residential air conditioners and industrial motors. Of course you would check the inputs to the module first. I saw phase 2 and 3 labeled on diagram. Is phase 1 connected to ground? Thanks for the Videos

[@DallasAutoDiag]

You could do that also. I'm gonna wait for another opportunity to make another video on one that operates and use advanced tools to check it. Preferably in my shop. This video is intended to the DIYer. The third phase is not grounded. That is a grounded shield.

Thanks

After replacing the fuel module do I have to program it for it to start?

[@DallasAutoDiag]

No programming needed

The blue and grey wire with the 2-3v ref
What does it mean when I don’t have that voltage on either of those 2 wires
