[Farmall] [AT] "After Tractor is running" questions.

[Ed Phipps]

    Ben,
  I agree with the short in the wire, however the throttle issue is simple. Either buy a new one from steiner tractor parts, or as I did on my 55 cub, put a flat washer between the lever and the spring. It will keep the tension enough to hold the lever where you put it. However, this winter I will replace the spring, or the the entire assembly, as old Farmall guys spot it real quick

Ben, I can't add to Mike's good comments on the hydraulics and throttle
lever, but I recommend you very carefully inspect all your wiring to make
sure it's hooked p correctly and to look for places where the insulation
could be worn through and allowing the wire to short to ground or to some
other wire.  (Bob Melville's wiring diagrams may help--can't recall if we've
talked about them before.  Check out

%20Diagrams/ if you need them.)

I wouldn't expect the lights to draw enough current to make the ammeter show
full discharge regardless of what the generator is or isn't doing.  I don't
know what kind or how many lights are on your tractor, but assuming they're
about the same as on M series tractors I'd expect the lights alone to pull
maybe 5 or 8 amps.  But full discharge, as in around 20 amps?  I don't see
how that can be coming from the lights alone.

I also don't see how the generator couldn't keep up with the lights if it's
able to keep the battery charged.  If the generator is working that well,
I'd expect the ammeter to show zero or very close with the engine running
and lights on--meaning the generator is powering the lights rather than
making the battery do it.

So, if the generator is keeping the battery up but somehow can't come close
to keeping up with the lighting load, and the lighting load sounds too high
to begin with, I have to think there's something other than lights pulling
that high current.  Must be a short somewhere.

  Just so you know, I am not familiar with Farmall Super A's working 
like they are supposed to.

That being said in the open now, I will show you a couple of 
observations that I have seen while driving the Super A.  What I need to 
know is whether these are normal or abnormal and what is wrong if they 
are abnormal.

1- When I work the hydraulics, engine full throttle, the tractor acts 
like I have overloaded the engine.  It struggles and gasps.  I was 
wondering if this was related to the air that was trapped in the lines 
(stupid mistake that I did) or maybe something else.  Maybe this is a 
normal phenomenon, but I am seriously wondering if, since the engine 
struggles moving the hydraulics when the hydraulics are not loaded, the 
tractor will be able to lift the snowblade.  Speaking of snowblades, I 
have some questions about it too, but I will send them a little later 
after I fiddle with the snowblade itself.

2- When the lights are one, what should the ammeter say?  My ammeter 
shows full discharge.  Does this mean the battery is running the 
lights?  The generator does charge the battery, so I know it works.

3- I have to hold the throttle lever to keep the engine in full 
throttle, otherwise the lever returns to about a high idle.  I hesitate 
to ask this, because I am thinking this is a result of the worn teeth of 
the quadrant, but I want to make sure something isn't adjusted wrong.

Thanks for your help.
