I have a 88' Ford 1910 tractor. The other day I noticed that the battery light came on and was staying on. ( I replaced the battery with new interstate battery approx 6 months ago- when it failed at that time). I tested for alternator output at the battery and there was none.
I purchased a new alternator, installed, and retested for charging voltage at the battery. It started at approx 15 volts and climbed all the way to 17.7. Only ran for about 30 seconds to determine this, and have not run it since. I hooked up my battery charger to verify that the alternator wasn't "working harder" due to a drained battery. The battery was nearly full when hooked to charger. So I trickle charged it to completely full. I Ran the tractor after topping up the battery and still have approx 17v at the battery when running. Only other thing I can suspect is the Voltage Regulator. This regulator through the ford/new holland dealer is $107. Was hoping someone could assist me with how to test this regulator before I jump to replacing it. Any help/advice would be much appreciated!!
***up to this point, aside from replacing the battery, i have had no charging system issues with the tractor, and all of the charging system parts are original (with the exception of the alternator I just replaced).
And I bought the tractor new...
Thank You
