Just left my sister’s house, was installing a new outlet in her garage and I remembered she said her ac wasn’t working. Checked to see if the contractor was pulling in and I was getting the signal wire for the contactor and 240v from both sides of the contactor and nothing was turning on. This is leading me to a bad capacitor, however I also saw a cut off yellow wire by the capacitor that I don’t know what it’s for. Which is why I wanted to see if anyone knows if the unit has a wiring diagram because I can’t find one online or if it is unique to the install. I was only able to find a user manual but it doesn’t show any wiring. If anyone one can help me out it would be a great help. I won’t be at my sisters house until Sunday. Unit model: Goodman ckl36-1D
