07 v6 not starting after zex window switch install.
Put the meter in "Ohms" test. Take the 2 probes and touch them together. You should get close to "0" ohms. Then you can pull each fuse and go across it with the probes. Good fuses should read close to "0" ohms. Open fuses (bad) should read close to infinity.
Well true, but most multimeter's will beep when you touch the probes together. Makes it easier, don't have to look at it just hear the beep.

um why not turn on the key and set the volt ohm meter to volts DC setting. Then ground the black or negative lead and use the red lead to touch both sides of each fuse then you know for sure your getting voltage across the fuse. JMHO
Unnecessary. Fuses either work or dont work. Waste of time. You can quickly and easily check them using the ohms function on mutimeter. When touching both sides of fuses if you dont hear a beep then the fuse is bad.
Whats a Tach Wire?
S197s dont have a Tach Wire persay....
7 posts just on how to tell a bad fuse from a good fuse.
Stealership time for the OP if fuse diagnosis is beyond him...
Get your Oscope out and trace the tach wire to find the
break in the insulation thats letting the signal leak out.
update, i checked all my fuses today using the ohms technique, and found one that wasnt bringing the meter down to 0. it was fuse F-40 on the diagram, the power wire from the coil is what sparked, and blew that 15 amp fuse. replaced it, and shes started right up! thanks for your help guys
