I need help with a John Deere 630 overcharging. The generator has been disassembled and checked by a repair/ rebuild shop and found to be ok. All tractor wiring has been replaced with a store bought harness (positive ground). The regulator was new and from the same place as the harness. The battery is new and shows almost 13 volts at rest. After putting it all back together and polarizing (gen/arm term to batt term) it seems fine for about 10 minutes then increases till the ammeter tops out at about half throttle (gauge only goes to 20). I opted to replace the reg again with one from a local auto parts supplier (crossed John Deere / Delco part #1118792 to Standard VR219) only to have the same problem. If I remove the field wire from the gen it drops to 0 amps, not charging at all which tells me I don't have an internal field short in the gen. The reg is mounted to the gen so the wires from one to the other are short, all visible with no short to ground. If I let it sit and cool for an hour or so or disconnect the battery, reconnect and polarize, it is ok for 10 minutes again. What's up with this? Bad 2nd reg ?

Today's Featured Article - On the Road with Dave Gohl: Auction Musings - by Dave Gohl. I was thinking the other day about all the auctions I've been to in the last few years. There've been many. Some have been very good, some have been well, disappointing to say the least. But no matter how good or bad auctions may be, we always seem to stay until the item we've come for or are interested in is on the block. I've been to some auctions near and far. I think the furthest has been the Two Cylinder 7 in the Amana Colonies last year. Lots of stuff, lots of people. I've also atten
