I have a 4115 Deere that has been Stating great and running great. Last time I ran it was 3 weeks a go. Never have had any issues with it starting and it is kept in a insulated finished barn. I went to fire up tractor Monday and the battery was dead. Tractor would only click when trying to start. Don't know why and the key was OFF. Tried to charge and quick charge for 10 minutes and still wont start. Jumped it with the car and all was well. Started pushing snow. Smelled an electrical smell 5 minutes later. Got off tractor and looked around sniffing. Found nothing and thought maybe it was just me since it was 2 out. Tractor died 15 minutes later.Had to jump it again and all was well till i put it in gear and it died. Check seat switch and it was fine. Towed tractor to my barn and started looking around. Wanted to check seat switch wiring at control module with my Fluke. Could smell electrical when I was under the seat. I pulled out the control module and opened it up and the resistors inside where fried. Had moister inside the box. Not sure if this was the issue or if the moisture formed do to the heat inside the box from the fault and then cooling down. Hate to put another one in with out knowing if something caused this??? I charged up the battery and pulled all 3 main power fuses. Hooked meter up in series and check amperage with key off. Put F1 in going to ignition switch and all was well. 0 Amps. Put F2 in feeding regulator/rectifier. All was well 0 Amps. Put F3 in feeding K2 engine pre heater. All was well. 0 Amps. With this said I don't know why my battery was dead. All these test where done with a bad control module hooked up, so not sure if that would have any affect or not. Don't think so looking at the print. Any help would be great. I know I need to check the charging circuit as maybe this ran the battery down the last time I used it. I cant fix the board as it damaged it pretty bad. Any one have one of these sitting on the shelf wanting to sell??
