Well, I thought I had this battle won last year, but its reared its ugly head again. I mentioned last year I thought the battery was bad, and you all agreed, but let me recap the issue. Engine will run all day, as long as I dont engage the deck. When the deck is running, electric clutch btw, the battery will die after a couple of hours or so. At the time, I was getting 14.3 volts back to the battery when running. I replaced the battery, and all seemed well, as the mower always started after that. With the warm weather we had been having, I decided it was time to get the mowers ready. I charged the batteries, and installed, everything went fine. Decided Id knock down the wild onions, so I ran this mower for about 2 hours doing that. Yep, battery died.
So I pulled out my meter and started checking. I have 12.4 volts at the battery, and at each place I should have battery voltage. Had to jump it off, but I only had 12.2 - 12.3 volts while running, so that tells me charging system is faulty. (Both fuses were good btw.) At the regulator/rectifier, 3 terminals, at B I get the same reading of 12.3 - 12.4 volts running or not, at the other 2, what A1 and A2 or something, I get 49 - 50.1 volts while running with the connector OFF of the reg/rec, but connected no volts.
First question, even connected to the reg/rec, shouldnt I see the same voltage? Second, thats high for what Ive read. If its suppose to be between 28 - 32 volts, does it sound like the stator is putting out more than the reg/rec can handle and burned it out? What would or could cause this pike in voltage?

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
