whtractors24 2,898 #1 Posted April 26, 2015 (edited) I did reading on previous posts still lost . I'm charging at 14.5 when I start it then it creeps up to 16ish and stays there . Battery is new I even tried 2 others still the same.... I believe full throttle no load I am getting 40 ac out of the stator . What to do to make it right ?

stevebo-(Moderator) 8,040 #2 Posted April 26, 2015 Are you checking on the gauge or on a meter? I would put another voltage regulator on if you are testing at that with the volt meter. 95% chance that is your issue. Share this post Link to post Share on other sites
whtractors24 2,898 #3 Posted April 26, 2015 Steve machine is a magnum 10hp has no regulator .... there is a relay I see ?? And I'm testing it with a volt meter at the battery Share this post Link to post Share on other sites
Wishin4a416 2,185 #4 Posted April 26, 2015 I cant help you. I never did get mine right. It would peg the meter after a few minutes. I tried almost everthing that was suggested here except the diodes. Share this post Link to post Share on other sites
whtractors24 2,898 #5 Posted April 26, 2015 The question is are you still running it ? If so is it ok... seems alot of people have same issue. My amp meter on tractor is stuck all the way left I tried others same thing Share this post Link to post Share on other sites
whtractors24 2,898 #6 Posted April 26, 2015 Got my stator off there isn't no diode on mine no one's been in here screws had oem paint . Share this post Link to post Share on other sites

gwest_ca-(File Mod) 10,491 #8 Posted April 26, 2015 One of the stator leads should have a diode after it comes out of the tinwork and usually right before a connector that mates with the tractor harness. Wire with diode goes to the battery. Wire without the diode goes to the light circuit only. Garry Share this post Link to post Share on other sites
whtractors24 2,898 #9 Posted April 26, 2015 So most of you guys think the diodes burn out ? Share this post Link to post Share on other sites
whtractors24 2,898 #10 Posted April 26, 2015 If I'm over 16v how many diodes to put in 1 2 or ? Share this post Link to post Share on other sites
whtractors24 2,898 #11 Posted April 27, 2015 well the one way circuit / diode coming off the stator is what knocks down the voltage to 14.5v. I found it and that's the only thing I believe it can be. there is not voltage regulator on the 310-8. if you lookup in the delaer site there is 3 different stators used on the 310 but 1 that says 310 ONLY... and of course that's the 3amp the one I have! the left one in the picture. part #7 KH10351 is the pigtail with the one way circuit/diode which is a TORO /kohler # discontinued The updated kohler part # is 25-755 31-S Im going to try to updating this pigtail and see if it knocks voltage down. I hope it works there's not much more it could be. the guys at the toro dealer I work at believe that's how that diode works and 16v wont hurt my machine, but I disagree.

gwest_ca-(File Mod) 10,491 #12 Posted April 27, 2015 If I remember correctly the voltage drop across a single diode is .6 of a volt. I have what B&S calls a voltage regulator that has only 2 wires - 1 in and 1 out. I need to find a 24 volt AC transformer and see what this regulator does to the output. I got one somewhere. Just need to find it. This problem was addressed in this service bulletin with the addition of a 113332 regulator which I am thinking is the same as the B&S unit. Off to look for that transformer.

gwest_ca-(File Mod) 10,491 #14 Posted April 27, 2015 This was discussed last year about this time I forgot about it. The B&S regulator is in the thread. Garry Share this post Link to post Share on other sites
Lagersolut 613 #15 Posted April 27, 2015 I cant help you. I never did get mine right. It would peg the meter after a few minutes. I tried almost everthing that was suggested here except the diodes. Neither did I, even tried a brand new Kohler diode, new volt meter on the tractor, new battery etc.... I still had 16 volts at the battery measured with a multimeter . Since this circuit off the stator was for charging only I put an on /off switch in on the dash and let the battery get down for a few starts .....seems to help ....last time out I charged at 14.5 volts or so, if it tops out I'll cut it off 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,491 #16 Posted April 27, 2015 Found the AC transformer and hooked it up to the 491546 replaced by 794360 9 amp 2-wire B&S regulator. Yellow lead to one transformer AC lead The other transformer AC lead to the body of the regulator and battery (-) post Red lead to the battery (+) post Used a 875 cca automotive battery that I knew was charged and has sat for about 3 weeks. Voltage 12.5 volts. The transformer voltage with no load was 27.19 volts AC Under load it dropped to 20.50 volts AC Battery voltage rose to 15.4 volts and stopped going up after 20 minutes. Shut it off for 20 minutes. Battery voltage rose again to 15.4 volts and stayed there for 1 hour. Readings were the same with 2 different digital voltmeters and 1 analog Did I do it correctly? Where is SOI when we need him. Garry Share this post Link to post Share on other sites
Save Old Iron 1,563 #17 Posted April 28, 2015 (edited) Wish there were 8 days in every week! I pulled an image from the Briggs site showing the regulator in a Briggs dual section stator. I did not see you mention a diode inserted into your test circuit. One version of the Briggs reg appears to be just that, a regulator and not a rectifier. Maybe add a diode in the orientation seen below. I'll take another look at this when the sun comes up. There appears to be at least 3 different types of R or RR units. If yours is an RR unit, from your description, you appear to have it connected together correctly. I said it before, I hate these 3 amp systems. Maybe I lucked out but the 3 amp system on my 211-5 responded very nicely to 2 diodes being added in series with the battery charger wire. On the other hand, its main duty is stop and start cart pulling, not 2 to 3 hours of constant use mowing. Edited April 28, 2015 by Save Old Iron Share this post Link to post Share on other sites
