Where to start? Well I have a 1971 Ford 4000 3
Cylinder Diesel. It still has the factory
generator on it. It has the gauge with
tach/proofmeter, fuel, temp, generator light and
oil light. It has been in our family for as long
as I can remember. My grandfather bought it used
and it was passed down to my dad and then to me. I
am in the process of fixing some items on it. I
just changed the oil, oil filter, tranny fluid,
rear axle fluid, wet bath fluid and lubed all
grease fittings. I am gonna changed the coolant in
it after I get new hoses and thermostat. I will
probably swap out the sender unit also. I just put
new tires on it last week because the old ones
were literally falling apart. Anyways I have
several questions.
1. The proofmeter and tach no longer work. I took
the cable loose and the cable turns inside the
sheath. I hooked it back into the tach/proofmeter
and was able to make the tach needle move. I took
it loose and hooked the other end back into the
generator and was able to turn the cable. I hooked
it back up but it would still not move. Took the
tach drive loose from the generator and it was
pretty clogged up with oil/dirt. Cleaned it up and
reinstalled but it would still not move. What
should I try next? Do I need a new tach drive,
cable or tach/proofmeter?
2. I took the instrument panel loose and took out
the tach/proofmeter. Like I said earlier I could
make the tach needle move but the proofmeter would
never turn. It was like it was frozen. Could the
tach/proofmeter be bad? Or is this to keep people
from messing with the hours? Guess this could
answer question 1.
3. While I had the instrument panel out I noticed
several wires were in pretty bad shape. Some had
rubbed nearly in to. I am surprised this tractor
has not caught on fire. Well I was going to hook
everything back up but I didn"t take a pic of the
layout and haven"t figured it out yet. I looked in
the service manual but the diagram doesn"t match
what I have concerning the wire colors. It appears
someone hacked on them in the past. I am thinking
of picking up a new harness from
yesterdaytractors.com or somewhere similar. Does
anyone have experience using a new harness? Is it
straight forward?
4. Before screwing with the instrument gauges I
got the cluster lights working. The generator
light came on and never went off. What could the
cause be?
5. Last but not least. The temp gauge works but it
moves over to red pretty quickly after cranking
it. Usually within a couple of minutes. The
coolant in it is pretty cool. The hoses don"t
really feel very firm but it has never boiled over
or anything. Thinking either the sender or the
temp gauge. Any opinions?
Thanks in advance. Oh and go easy on me I am not a
mechanic or electrician. I am learning as I go.
