Have you ever had an electrical problem with your appliances, car, boat, or motorcycle and thought, "Hey, I'm handy; I do mechanical work on my ride all the time. I can handle this." So you grab your book of wiring diagrams and unfold the page.
And then it sinks in. It's a totally foreign language and looks suspiciously like the spaghetti you had for dinner last night. Wiring diagrams can be tricky to trace through when troubleshooting an electrical circuit.
Don't despair; it takes a process and a bit of knowledge about electrical symbols. This Temperature Control Division site will guide you through the process of tracking down the problem. It makes the "overwhelm factor" a bit more manageable and gets you started on the road to electrical recovery.
