I am on step 28 of the T15. When I use my DMM to make resistance measurements on pins 1 and 2 as well as 3 and 2, my DMM reads "1". It looks like it is not passing a signal. I get a signal if I measure pin 1 to D9 (black side) and I also get a signal if I measure pin 2 to D9 (colored stripe). D9 reads properly on my DMM.
My DMM's resistance scale goes from 200 to 2000k ohms.
I am a novice at this but I think I've doublechecked everything. Am I not supposed to be getting a signal here? Thanks
