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.

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.

no just use the multimeter, put it on ohms setting. Touch both sides, should beep meaning fuse is good if it doesnt then you found the problem.

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

Glad to hear it was that simple. Guess you did not have to make a Dealership run after all! Amazing what a bit of research and testing will do for us.
