I'm trying to get the charging system working on my father-in-law's 140. I'm not sure what the year of manufacture was but it is a 12 Vdc system and it has an alternator. My father-in-law says it keeps running the battery down soon after it has been completely charged using a separate charger. I checked the alternator and the best I could tell the alternator has no output. We now have a new Delco Remy alternator but I wanted to better understand the electrical system and verify the tractor is wired correctly before ruining a new alternator. I looked for an ID number on the tractor that might help you know what vintage 140 we have. The only number I found was on the transmission case and it is 58353 followed by a U or J. It's hard to tell from the stamping in the metal. Any help would really be appreciated. I'll be glad to provide any info about the tractor or take any pictures that you need to determine what the correct charging system should be.
A couple of questions I had from looking at the wiring are: Does the charging indicator have to be connected in order for the charging circuit to be complete? It is not currently connected. Also, Is that a resistor attached to the rear of the alternator with the wires terminated at each end? Seems like it measured about 30 ohms. No sure what it was for.
