Tachometer doesn't work

[martingregg598]

Hi Ryan, personally I would want to be absolutely positive that these
wires are good all the way back to the other end. After you find out
where they go then you could run a continuity check or in this case a
non-continuity. If the insulation is melted off, there had to be a
problem, maybe the old tach, maybe not, maybe to much current running
through them, if that is the case they could be melted in other spots.
I would think that if a wire had gone to ground then there would have
been a short that would have taken out the fuse or breaker. Do the
wires themselves look burnt? A lot of times when there is too much
current, the copper strands will be burnt, if that is the case, the
wire is bad.
