Ok. Is it just me or does everybody else fight voltage regulators on tractors.
I have a 6 volt generator on my MM UTU, it is not the correct generator for the tractor and it lost its Identification tag, but it still works/should work. Last week it worked fine, this week nothing. I did replace the battery, but it worked fine for the next few days after. Today nothing. This generator / regulator has been checked out and gone through by about 3 diferent guys in the last 3 years. They check out the generator and sell me a new regulator. It might work for a year then I start having problems again. Half the guys at the repair shops say why are you bothering, just convert it to 12 volts. I would like to keep it a little bit original, besides when it works it works fine and when the battery is fresh it has plenty of cranking power. It is only when the generator/regulator starts giving me problems that the battery power goes down and won't start.
Ok. I am ranting here but how long would you expect a voltage regulator to last? I do live in a wet climate and it does get abused sometimes by being left out in the rain.
Also I have a Co-Op E-3 with a regulator that at an idle shows slight discharge, if I hold steady at about 1/3 throttle shows +8amps steady, and full throttle the needle jumps between 0 and 8, might hold on +8 for 5 seconds then jumps back and forth for 5 seconds. Sometimes (1 in 15 starts) the generator will not put out anything until I tap on the regulator. Is this normal?
Are these just bad regulators? How is it that I am this unlucky? Did farmers put up with this in the day, or are we just getting junk regulators today? Is there any maintenance that I need to do to my regulators? If you don't have any advice, am I alone with these problems?

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
