Hello to you all here at the TFP community. I am an engineer and fairly avid tinkerer, although I have no professional pool install or repair experience, I have repaired or replaced almost all of my pool equipment at some point. I recently added a Jandy JXi heater and managed to damage it by hooking it to 110v when it was set to 220v instead. I am looking for ideas on what I may have damaged and how to check.
