After replacing the entire fuel and electrical systems, except Starter and Generator, I tried
a new push buttom start switch..The tractor finally started up and ran good. Cut my whole field for two hours and loved every minute!

Battery discharges though..need new generator and probably new starter motor too.

the "fuel sediment bowl leak" turned out to be a nylon fitting above it, to the fuel line, not the sediment bowl.

But, thanks to all of you who wrote to assist me over the last few months. Great bunch of guys you are.

Does anyone know where I can get a rotary mower deck which can run off the PTO on my H?

I'm currently struggling with an ancient John Deere Sickle mower. Thanks.

 Congratulations! in reply to hbauer, 09-05-2007 09:51:43  
I am happy to hear this.

I am ALSO happy to observe you are apparenlty paying attention to your dashboard ammeter. So many people, when they first encounter what they think is an electrical problem, start unscrewing and replacing caps, rotors, coils, condensors, etc., etc., without really having a clear idea of what the problem might be; the dashboard ammeter can often help us narrow down the potential sources of the problem.

Before you decide to replace or rebuild the generator, you might want to try the following tests:

(1) Look for obvious physical problems: burned wires, wires dangling loose, slipping belt, etc.

(2) Get one of those test wires with alligator clips (or crocodile clips, depending on how you hold them) on both ends. Clip one end to the regulator base and the other to a good ground connection. If the ammeter suddenly shows a charge, check and clean the grounding surfaces.

(3) Run your test leads between the ARM or GEN terminals and the BAT terminal. If you show a charge, you can take the regulator apart and try to clean and adjust everything, or you can try a new regulator.

(4) If none of the above has made a difference in the charging rate, run your test lead between the FIELD terminal and ground. If the charging rate increase, ditto the above about cleaning or replacing the regulator.

Thus easily, using a simple wire and the invaluable dashboard ammeter, can one diagnose many common voltage regulator failures.

I don"t know what to tell you about whether to replace the regulator or clean it. On the one hand, there is a good chance the regulator you already have is more rugged than any replacement you"re going to find.

On the other hand, not all regulator overhauls are successful, and then one has wasted time...

Thanks, Bohemian. A nice practical analysis of testing procedure. You're a man after my own heart!

I thought of the regulator, but dismissed it as a last resort test. My experience with them is that they last almost forever. But, it could be defective and I should not make any assumptions. I will do as you say.I have some other electrical testers which I can also use. I do have some electrical background both through work and schooling..in fact a lot of it, but I won't bore you.

Thanks again. h. bauer
