Hey snow men! How's it going?!

Was hoping you could lead me to the right direction.

I have been having the P8 error on my mr slim AC unit. I know that it has something to do with the outdoor unit.

My initial finding is that on the outdoor unit, there is no 12v present on the relay to power up the contractor. Bypassing the relay would power up the outdoor unit so I think the 12V that is supposed to be coming from the indoor unit is not present.

Am I missing something on my troubleshooting?

What should I look at the indoor unit to check the 12v?
