184 overcharging battery

[Eugene]

Remove the ballast resistor and install the diode Larry B suggested. That's also my suggestion.

I'm assuming you purchased a 3 wire alternator, the standard Delco 10SI. I have the 3 wire 10SI on 2 tractors. I use a toggle switch instead of the diode or lamp to excited the alternator and to disconnect from the alternator. Start the tractor, flip switch on, alternator starts charging, promptly flip switch off. The only problem with the switch is that if you forget to switch to off, the battery is discharged over night. Perhaps I shouldn't have told you that.

Easiest way to add a diode. Will need to connect the resistor wires together.

Ok I will order this. Thanks a ton Larry and Eugene. Any chance either of you could explain where the different wires get hooked up with this kit? I plan on taking some pictures and adding to the post once I get the diode kit. It should make for a pretty good "how to" post for everyone.

More than likely there will be instructions included in the kit.

If you have questions after the kit arrives, post photos of the packaging, front and back, and the wiring.

From the appearance of the kit you will probably need some heat shrink, soldering iron and electrical solder.

It is very simple. You probably won't need the plug with the wires.
Remove the existing resistor on the back of the alternator and connect the wires that went to it together. Either solder and heat shrink or a crimp connector. NO BLACK TAPE. Then unplug the connector from the alternator and plugin the diode pack to the alternator then plugin the tractor connector to the diode pack. This is important, secure the wires so they don't move and shake. The vibration and movement will break the diode leads. That's it. Start tractor and check that it is charging the battery.

Thanks a lot guys, I really appreciate it. The part is already ordered, can't wait to get it put in.

Or if you want tp take the really lazy way out, just plug the diode pack in as Larry B described. Leave the existing resistor in place.

LOL....that would definetely be the lazy way out since it is one bolt.

Side note....I picked up a little lockdown project for myself today. I know it is probably sacrilegious to post here but what do you guys think?

Actually, Larry, the diode can simply be installed in place of the resister. Oh, Jim already said that! This thread put me in the mood! My Cockshutt 20 has been running a 10si with an early 1 wire conversion and working ok for many years. The only issue was that the engine had to be sped up quite a bit to get the alternator to self excite. I ran it in the shop, yesterday, and added the diode. Now it's charging the moment it starts. I'm not sure why I didn't do this a long time ago.

Just make sure it is out of gear before you pull that handle!

SUCCESS!! My package arrived a couple hours ago and I just installed. Very easy as described by Larry and took about 10 minutes. Fired right up and charging at 14.73v and shut off with the key! I will post some pictures. Thanks a ton guys!
