Well its time to sell or at least been trying to sell for for about 10 months been putting it out front of the house. 6 V system. Kept a battery tender on it. 100 bucks a pop for a 6 V battery Id like to keep this one charged up. In the last 2 to 3 weeks Ive noticed that after starting it up and letting it warm up maybe 10 to 15 minutes. The amp meter is still showing about 20 on the Charge side and not going down. Im almost certain that prior to 2 to 3 weeks ago that after letting it run The needle would just be above the 0+ on the charge side. More electrical gremlins in the shop or is the charging system doing what its job is. Thanks for any input

If the charging voltage is 7,0 to 7.2 when it is charging measured across battery posts) while warming up, and at 1/2 throttle, it is OK. more than 7.4 is
overcharging. An analog (needle) type meter is needed to assess the volts, or an expensive digital. Jim

Really need a voltage reading across the battery to know what's happening.
A good analog meter will be the best, sometimes the arcing points in the
regulator will confuse a digital meter, but if you have one try it.
It should level off around 7-8 volts, engine running up to governed speed.
If it's going higher, something is wrong with the charging system.
If the charge rate stays high and the voltage is low, the battery is suspect.

If the battery is good with no internal shorts ??? (other than may need charged up) and there's no other shorts or excessive loads??? if the
charging system is working Id expect the charging amps INTO THE BATTERY to back off much less then 20 after time or risk overcharging the
battery. Maybe there is another current path which keeps the genny running at full bore instead of all going into battery ?? As the other
sparkies mentioned a voltmeter on the battery can help and Id expect maybe 7 or so volts on the battery until (subject to RPM) its charged
then (subject to Voltage Regulator and Genny) maybe level off to 6.5 to under 7 depending on load........If theres a short in the charging
system or the VR is bad such that its full fielding all the time that could cause it to constantly max charge. I think that 44 might be a
Class B Charging System Im not sure..

Oh just wonderful thats kind of what I thought possibly could be happening but you would think you would see smoke fire or something shorted out.
Well here in a little bit Ill pull her back into the shop and check the voltage across the battery thanks.

More than likely it's a battery problem.
Try leaving the tender off for 24 hours, then check the voltage across the
battery not running. Suspect it will be low and probably no, or very slow
start.

Points could be sticking in voltage regulator.
My SC Case had a 12 volt battery with six volt generator when I bought it in 1990. I put a six volt battery in it and polarized it. And does charge. BUT it
charges 20 amp all day long every day. I have filed the points in the regulator and few times and then the regulator will function correctly. Charge 5 to 10 amp
for a few minutes and then go back to zero. Doesn't last more then a few hours and the points stick again and back to 20 amp all day. I don't put more than 2hrs
a month on it. So it really doesn't hurt anything. I get anywhere from four to eight years out of a battery.
The Bomgaar store lists six volt batteries for $79.00. Have not tried one. Will next time I need one.

7.5 is high. If you start the tractor often, and operate it for moderate times each, it might be OK but it should be down around 7 to 7.2 volts (equivalent to
charging at 15 volts on a 12v system. above recommendation. Jim

Happy Easter to all.
Well I couldnt take it any longer , tractor has been sitting for 13 hours and pulled the battery out. With my harbor freight meter checked voltage of the battery had 6.4. Then get out my battery hydrometer and checked the cells all in the green. OK put battery back in and fired up and let it warm up about 15 minutes. Amp meter is down to about 8 on the charge side Check voltage at the battery after 15 minutes of warm up had 8.2. Now Im leaning towards the voltage regulator because I did check the Genny output was 8+.
