I pulled this stator off an old Briggs that was in a mates Greenie and he never complained about it not charging and the other half was not inside the flywheel, so I can only assume it was working, just have to work out what rectifier I need for it
Hi AVB, What surprised me with this is my mate never complained about it not charging, but not long after I fitted a new Chonda to his Greenfield he rang me and said he didn't think it was charging. I asked him why and he said he didn't know just thought it wasn't. Next time I was up the bush at his place I put the multi meter on it and 14 volts no problems. I have fitted a few Chondas on rideons and I have always just plugged the Chonda stator wire into the existing plug and they have always charged fine
Hi AVB, I assume I just plug this into the plug coming from the stator and the red wire goes to battery positive and this should be the same if I fit a Chonda motor to it which is looking like the better option?
Norm, This why we must first determine which stator you actual have. There are multiple configs out there as you could see from the chart I linked. That voltage reg you linked is for 10,13, and 15 stators. Then there is the dual stator which has just a diode for the DC side and there is AC side for lighting.
Thanks AVB, Pretty sure these 2 Briggs will go to the scrapper, I'm not wasting any more time on them, for $450 I can get brand new 14hp motors, bolt it on and instant start So I'm thinking that the half stator I had was the D/C side of the stator as it only has a single wire coming from it. Interesting is that I just plugged the new Chonda stator wire into the existing plug on the Greenie and it charges fine and has been running for quite a few years now
Ok my latest saga with the 2 Briggs motors not charging. New stators, new rec/regs and still only getting about 10.6 volts out of the rec/regs. My head was hurting and I had no idea what was going on, getting 25 volts A/C out of the stator. In the end I cut one of the wires from the stator and instantly 13 volts at the battery. I did the same to the other motor with the same result, charging problems solved. I have no idea why they work like this but they do. It is charging fine using half the stator. Anybody have any reason why this is happening because I certainly don't have a clue
Here is a suggestion Norm that can help a lot. The posting of the model and type numbers and the PN of the stator you are working would certainly help those like me that is half way around the world. It is something you being doing for all the equipment as being able to see the IPLs is usually very helpful in troubleshooting.
Personally I gave up on the crystal balls as they are just to cloudy lately.

It kind of sounds like the wires were mixed up going to the rec/reg ,the 2 wires from the stator ,one wire goes to the rec/reg for battery DC charging and the other wire from the stator is an AC current that goes to power the headlights and remains AC.
Thanks Max, I did think that might have been the case. These stators just have 2 yellow wires and no diode in either one unlike the ones with the red and black wires with the red wire having the diode in it No mushrooms here AVB, I don't know what these numbers are these covers have been swapped around and on this OHV motor I'm not even sure of the HP because the sticker was missing, it has the Intek plastic fan shroud. I'm just guessing it is 10.5 I'm playing a guessing game as well, but alls well that ends well, both batteries are charging and I can move on to my next problem machines 3 Deutscher rideons that have been sitting here for many years
That is an AC stator and requires the 691185 regulator. Cutting a wire should had killed it as the windings are normal not grounded unless there is a defect in the stators. but of course the ones I referring to are full circle stator and not a half circle ones.
So something just don't sound right.
Also there a MS sheet that might need applying as there is possible shorting issue.
Yes AVB, Mystery to me the stator and re/reg came in the one package and plugged together so I have no idea why they would not charge, putting out 25 volts A/C but as soon as I plugged the rec/reg in I could only get 10.6 volts D/C coming out of the red wire. I tried bridging each yellow stator wire individually to the rec/reg and both wires delivered 13 volts to the battery so it didn't matter which wire I cut
Still scratching my head a bit with these charging systems. The stators with the red and black wires with the red wire having the diode in it, does this diode rectify the voltage from A/C to D/c or does it just prevent any backfeed into the stator. I hear stories that this wire can go to the battery but if this is the case there in no regulator to prevent overcharging the battery?
I think you have the gist of it ,A rectifier on the red wire converts alternating current (AC) from the stator into direct current (DC) for the battery. It also acts like a diode by allowing current to flow in one direction (to the battery) while preventing reverse current from flowing back to the stator, protecting the electrical system.
Yes, using a voltage regulator between the rectifier and the battery is generally a good idea in applications like this.
As we know. Voltage Regulation: The output from the stator and rectifier can fluctuate depending on the engine speed. Without regulation, this voltage could exceed the battery's rated voltage (usually around 12.6 to 14.4 volts for a standard lead-acid battery), leading to overcharging and potentially damaging the battery.
