Speedometer reads very high, then very low and sometimes seems
accurate, I am thinking about replacing the Speedo gage in the dash,
any suggestions.

Dale,
On my '78FC my speedometer has similar problems. I am planning to
send it to a shop in Lncaster PA. to see if they can fix it. I will
update the forum when I get it back with the cost and results. I want
to maintain the same guages for appearence.

I had a similar problem on my 82FC and it was a very dirty sensor on
the rear axle. One of my brake drums has notches cut in the edge and
a sensor reads the speed of the notches and signals to the speedo.
My sensor was covered in mud and dirt. After a good cleaning,
everything has worked fine. Hope this helps, a lot easier than
pulling a speedo.

Dale,
My '78 has a mechanical spedometer. I got an estimate of $150 to
$200 to fix it.

On the '84, there is a speed sensor on the rear of the brake drum,
curb side. They go bad, and are only around $35. On some '84s there
is another one on the left brake drum, the cruise-control was
separated for interference reasons. The speed sensor if original is
likly to break when you attempt to free it from its rusty lock-nut. I
had to replace the sensor on two of my FCs

On the '78 mechanical one: I replaced the speedo on my '77, used a
new electronic speedometer. You can buy the new Teleflex one if you
want (matches), or go with a new VDO programmable, about $100 I
believe. For a speed sensor I used a driveshaft pickup, four magnets
on the front of the driveshaft and a pickup coil (easily) mounted
above it. On another arrangement I used the '77 speedometer cable to
drive a cruise-control AC signal generator, also easy to find at your
local NAPA et al.

If you go VDO, you can buy the matching programmable tachometer,
forget about the problematic tach drive on the FC, and drive the
tachometer from the alternator, a fairly simple modification. buy the
tachometer with the hourmeter in it, memory tells me that the '78
didn't have an engine hourmeter. A Teleflex industrial/international
tach with hourmeter used to be available to match also (as in the
later FCs and PTs), not sure they're still available but it's what I
used in my '77.
