I converted my tractor to an alternator. Wired up as shown in the instructions. Fired it up and it charges fine. Shut it off and the battery went dead in about 5 minutes. Jump started and charged the battery. Shut down and disconnected the hot terminal. Put on ammeter and it shows 4 amp draw. I know there's a short somewhere. HELP!

FYI: Nowhere in the instructions for the alternator conversion does it tell which way the female red/black plug goes on the alternator. Flipped it over and problem solved! :D

They don't charge by the word here...
Yes we know if you converted the tractor to an alternator you would have removed the original V reg.
But alternators have v regs too. Some, like a GM/Delco 10-SI are internally regulated and are very simple to wire - either 1 wire setups or 3 wire setups. Some like Motorolas, have an external regulator and are harder to wire.
Is is this a kit you bought somewhere?
Got a link to it?
Photograph of it?
There are several guys here who are very good with tractor electrics. Some are electrical engineers. Some have 30, 40, even 50 years of experience working on tractors.
They can help you but not knowing what you have.

Type/brand of alt you used, internal/external regulator, etc.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and ... [Read Article]
