First off i will admit i have seen the error of my ways in that of using a 8volt batt. and will get a new 6volf tomorrow. Having said that the battery will go down where it will not start the tractor-----sometimes in ten days, sometimes in like three days. I tried a motoring generator test and it will do this i have however never seen the amp hand move even the slightest amount toward the + side. Usually just hangs on "0" Direct me to a study guide of trouble shooting this or should i put batt. on and get a new regulator and see what this does ? This 8volt is only two months old and i can remember us using them like a million years ago with no problem. Thanks for any help in what to do next.
