Tachometer fix

[Jeff Miller]

The flat bars have holes that are offset toward the inside, have to
be installed again with the holes offset toward the inside/fan shaft.

The tach drive on the '83 is an AC type, also used as cruise-control
sender of that vintage, should increase frequency at increased RPM.
You could use a DMM with a freq. counter on it, see if it is relative
to RPM increase. The only other check I can think of is to put the
output on a scope, and you can drive the sender with a drill if
you're careful.

Check the angle-drive, spin the input adapter with one hand while
providing some resistance to the output cable and see if it slips
internally, some do as the bevel-gears wear. Could also be the
tachometer, although I've never had one fail. The angle-drive is
apparently a special part, I've never been able to find one with a
long enough input reach to clear the engine with a sender on it. BB
should have the angle-drive, and I believe that HMH in Holland also
has a cache of them on-hand, but haven't been there in a while.

Previous years with the 90degree sweep tach. are driven by a DC
generator sender made by AutoMeter.
