Posted this somewhere else and figured it was a good idea....
There aught to be a sticky with general troubleshooting advice.
But heres mine:
There aught to be a sticky with general troubleshooting advice.
But heres mine:
- Draw out a Line Diagram or Schematic to help visualize the circuit. And up-date it as you go along.
- Always test against known sources - test the end of an extension cord H-N-G to grounded plumbing will help confirm that it is a "known source" - then you can take this extension cord (one phase, a neutral and a ground) with 3 of 4/5 known sources to what it is you need to troubleshoot.
- Know your equipment... The differences of operation of both a DMM, and say a wiggy can be misleading if you don't know how to interpret them.
- Always follow the rules when disconnecting any conductors... Disconnect ALL ungrounded conductors first, then grounded, and if needed grounding.... IN THAT ORDER!
- If it worked before - it is not a wiring pathway problem. If it never worked before it just might be a wiring pathway problem.
- "Divide and Conquer" divide the circuit into operational and non-operational parts - then further divide the non-operational part.
- Follow a 'short' away from the source to the ends of the circuit, follow an 'open' from the ends of the circuit to the source.
- Use your head, not your heart - follow safe working procedures when dealing with energized conductors.
