Over the past several weeks I have posted about charging problems with my H. Everyone's posts were very helpfull and I have grounded my feild terminal on the genny to a bolt that was out there close by. Re-polarized and ammeter went to high charging side. When lights come on the needle drops quite a bit but does not go to discharge. I placed my multimeter on the battery with lights off and tractor running and I am getting a reading of approx 13.8 volts. My question is that I'm only running a 6 volt system. Am I gonna fry my battery with this high voltage? Is it possible that when my genny was rebuilt it was mistaken for a 12 volt? When I turn my lights on with the tractor running I drop approx .2 volts. I've also had a problem with my antifreeze bubbling and coming outta the overflow tube, I'm talkin a steady stream comin out not just a few drips. I did not have a problem with this before I grounded the genny feild post, it may have nothing to do with the charging system but I figured I'de throw it out there. As always, any help is appreciated!
