poor charging above idle

Recommended Posts

Posted (edited)

At idle or low RPMs it will charge but if i turn on the PTO or headlights it discharges. Also if I raise RPMs without turning anything on it does not charge. The battery is new. I just received this tractor it has been sitting in the woods for a few years. It starts right up and it has a Kawasaki FC540V engine.

Tractor is a 257-H 

 

Since my original post . The charging system came to life on its own .It is now charging above 17 amps .I replaced the key switch  ,removed cleaned the rectifier plug and base . cleaned the ground terminals .  I am still trying to find out how many years this tractor sat out in the woods. When I have time I will test the rectifier with the chart Garry posted.

Thank you everyone. I will post the results sometime next week.

Could be a 257-H if there is a typo somewhere. Listed as FB540V here

Part 2 of this manual covers the charging system.

Have never seen this before to diagnose the voltage regulator if it has 6 terminals.

:text-yeahthat:

That's a really interesting chart to diagnose a voltage regulator.

Tells exactly what terminals to probe and what the meter should read.

I like the instruction - Do Not Use Megger. You just don't see that kind of stuff anymore. Heck, I haven't seen a megger since the mid 90s and I'm in the test equipment calibration business!
