Turning Coach Light by Backdeck Patio Door tells us the GFI Plug has been Powered Up.. Had no problems till now, was using the Mittor Saw and in between jobs we noticed the Coach Light was Out.. Pressed Test / ReSet Buuton a couple times , the indicator light wasn't shinning.. Unfortunately for us the Panel has No Numbered Ledger indicating what Breaker is for what.. Flipped all the Single Pole Breakers Off/On.. Don't have a Meter to Check Voltage either.. The Junction Box the Coach Light / GFI Plug is wired into is just one 14-2 Wire from the switch just inside the Patio Door.. Could the GFI Plug have gone Dead / Defective.. The Coach Light / GFI Plug Receptical came as such from either Home Depot or Lowe's all in one moulded box...Help Appreciated , Cheers Thanks
