Farmall 400 fluctuaing voltages

Posted by JaredFarmall400 on September 03, 2006 at 20:03:43 from (66.163.158.179):

Hey everyone,
Went to hook a electronic tach up to my 400 today and it did not
work. Following hours of testing I determined that for some
reason when I run the tractor the voltage that comes through the
system is very unpredictable. My multimeter goes from 2v to
160v's and it all over the place. However, it only does this when
the tractor is running. When the tractor is stopped it reads a
solid 12.6 volts. I have always had a problem getting this tractor
to charge the battery properly, always seemed like the battery
was going dead. Thought the voltage problem was releated to
the gen. So I unhooked the voltage regulator and the gen belt
with the same results. I even tried hooking up a seperate
battery to the ignition. The ignition battery showed
fluctuatingvoltages and the rest of the sytem showed good. Not
sure what is causing this problem, but I can't get the tach to
work and I am thinking this is causing the gen to not function
properly. The battery is hooked up positive ground and the
tractor was converted to 12 volts at one time. Do I maybe need
to reverse the polarity to negative ground? Not sure what to do.
Any comments appreciated. Thanks
