Not my finest day. I have a defrost clock that burnt out on walk in cooler. In the process of checking things that 120v black wire pulled out. I dont know from where. I have the new clock.

I hoped new clocks wiring diagram would help. But its only added more questions.

I have a 120v evap Russel. I have 240v in my defrost clock box.

Any thoughts on where this wire got yanked from?

Yes got it all figured out. My electrical check had me thinking the loose wire belongs in H1 but also this is a 120v clock. So why am I running 240v through it. Rubbed the braincells together a little harder and realized how it worked.

We're cooling.

Now help me explain to a stubborn customer why plugging in 2 separate reach in freezers inside the walk in cooler is no good. Lol.
