Test Lamp at NAPA
I recommend this tool for many things. If you have a 12 volt side of life issue this tester, which has a small incandascant lamp (like a dash indicator lamp) in the clear handle. is a godsend. It puts a small load so it will find a bad connection when a volt meter will not, and it has basically 3 states Bright, Dim, Dark (Bright is good dim = bad connection dark = no power)
Start by testing a known good spot (battery)
Then ground the clip and with the lights on touch the two windows on every blade fuse
Dark-Dark Not the fuse you are looking for (Star Wars pun)
BRIGHT-BRIGHT good fuse
Bright-Dark or Dark-Bright BINGO
