600 overchatging

I just got a 600 and it was not charging. Put on a new regulator and now it charges over 30 amps. If I idle it down it stops charging and won't go up again when I rev it back up. Then when I polarize it again, it starts charging at over 30 amps again. Is this regulator any good? Thanks, Jesse.
 
I'm assuming this is the original 6V system for this reply.

You definitely have something not working right there, but let's
start with it charging at 30 amps. Is the battery fully charged?
If the battery is low on initial startup, it should charge at a higher
rate until the battery is charged, then taper off to nearly nothing.

The charging stopping when idled down may be due to incorrect
pulley or belt size. Are you running the original 5/8 sized belt?

Polarizing has to do with the generator, not the regulator, so I'm
not sure how that fits into the equation just yet.
Most 6V regulators on the market today are less than stellar.
I've had them work for one hour and quit for good. YMMV
 
Yes, the battery was discharged all the way, although it is a new battery and should come back pretty quickly. It is a 6 volt system and the original belt and pulley size. I
have just never seen the amp meter go that far to the plus side. And when at idle having the amp meter just stop also didn't seem right. I thought it should at least slowly
back off and always show at least a little charge. Thinking the regulator is either fully charging or fully not instead of regulating. Thanks for the help and any other ideas.
 
Put a voltmeter across the battery when the engine is running. Ideally it should bring the voltage up to about 7.2 volts and hold it there. If it goes above 7.5 volts and keeps climbing, the regulator is not doing its job.
 
regulating on a mechanical voltage regulator is basically charge averaging. you have some points open time and some points closed time. think of it as duty cycle. If the battery was stone dead and you jumped it.. that's asking alot of a 150W generator... even moreso form a dubious quality regulator.

Ensure that you have good ground at the generator, regulator and battery. IE.. all a common reference. Then do a voltage check.
 
I have good grounds all around, and just measured voltage at the battery terminals with the tractor running and it was measuring 16.5-17.5 volts. Seems too high to me. I am leaning to that new regulator being the culprit. The brand was called Sparex, made in USA for about $45.00. The package said it replaces FAG10505A. Got it at the local NAPA store.
 
You have a 6 volt battery being charged at over 17 volts? I have a hard time believing that! That battery should have long been exploded by that point, I would think anyway. If I saw a 6 volt battery at 17 plus volts, first thing I'd do is shut the engine off and run away, because it's a ticking time bomb!

I question the accuracy of your meter. Take that same meter and put it on your car battery. Voltage should read 12.6 to 13 something, depending on how long it's been sitting. Voltage should rise to 14 something after you start the engine. If that checks out, please go back out to your tractor and take your readings again.
 
I haven't ran it very much, only a few minutes at a time just because of that. The battery was run down almost all the way, not able to turn it over anymore, so it has some charging to do. I have a new regulator coming from YT, so Ill let you know. Thanks for all the help!
