2305 not charging

[Rl69]

So,like the title says my tractor not charging. Battery is good connections are clean. The alternator is puting out 30.86 amps ac. I'm not geting any thing out of the rectifier. I have continuity between the hot and neutral posts of the rectifier ac in.

My guess is the rectifier is shot John deer wants 147 bucks for the part amozon wants 25 ????


I'm not a macanic by any means, and I know much less about electrical, dose it seam like I'm on the right track?
And why such a discrepancy on parts price.

One last thing I can read the battery all the way back to the rectifier. That seams wrong.

As you can tell I don't know enough about all this to even know what questions to ask

G'day Mate and welcome to TBN from Downunder.

The first question is, and this is important, where are you located? Generally speaking. Because if you're in Wisconsin with that blizzard and the sub-zero temperatures then that cold be a factor. If you're in Yass, NSW, then the +30C temps could be a factor.

Enjoy the site.

This has been going on for a year, or more... I thought it was the alternator and would just charge the battery up the night before I needed it. I found a guy who repered altenators and took it to him. When he told me it was good I started hunting the next possibility.

OK. My next question is can you jump start the tractor and, if so, does it stay running until you shut it off?

I don't know your tractor but it appears from internet search to be a small one with small gas engine?? When my Gravely with the Onan engine had charging problems, Gravely wanted $275 for the rectifier and some other parts.. I put a $10 rectifier on (had to splice some wiring), works great and that was more than 10 years ago..

If I recall, some charging circuits require the headlights to work (always on) before they charge properly.. I think my Scotts mower with Kohler engine is that way.

Yes I can jump start it and it will stay runing

It's a 23 hp diesel engine Koler I think

You have a Yanmar diesel in the 2305, 3 cyl 24 hp

How old is the battery?

 

[Rl69]

The one on it now is a few days old. It the secound battery sense it has stoped charging

Many times a rectifier has 3 wires coming in from the stator, a ground and red wire. You want about the same resistance between the 3 wires (3 tests). You don't want your positive wire to have continuity with the ground. Now, test the diodes on the 3 stator wire connections by using the ohm meter. Test each one to the ground connector and they should be closed. They should be open to the red side.

When the tractor is running, what are you getting for voltage at the battery? If you get 9-10 volts There is safety relay and a diode that are a common problem that cause a no charge with the 2305..
