I have a Max II 6x6 with a B&S vanguard engine. The engine does not recharge the battery like it is supposed to. All of the connections look fine. If I turn the headlights on, the ammeter on the dash responds by dropping to the drain side. When idling or accelerating, the needle doesn't move. According to B&S troubleshooting, I am getting power from the flywheel but not out of the regulator. Looking at the parts diagram I determined the part to be 691185 as seen on page 25 of this link:
http://www.briggsandstratton.com/ipl/pdfs/100/MS2263.pdf
The picture for the part is on page 14. The ref number is 501 (not the A or B). The only thing I don't understand is the B&S part has a different connector than the AATV. The one on the AATV is a small square connector with a black wire coming out of it and the one from B&S has a small round red connector with no wire coming out of it. Does the Max II have a special regulator or can I cut the end off of the existing regulator and solder it to the B&S regulator?
Thanks for any help. |

Aubrey, Sounds like you have a bad battery if your ammeter indicates a drag when the lights are on, but doesn't indicate charge. Check the ammeter right after the engine starts (assuming you have battery enough to start it) - if you get a blip of charge and then nothing, you have a bad battery. Also if your lights dim at idle and brighten with a little throttle, your charger is okay; bad battery. |

I bought the AATV secondhand and the previous owner put a new battery in it. The AATV would crank itself until the battery no longer would turn it over. At that time I emailed Richard about how the battery gets charged and he replied that the engine charges the battery. So I looked at the B&S website and found some troubleshooting material including the parts list mentioned above. I am getting power from the flywheel - at least with a voltmeter on the input of the VR, it fluctuates as the engine is revved. I don't have an adequate ammeter to check the current out of the VR.
Right now, I an stuck with the old manual starter (puff-puff) or charge the battery up for a few more electric starts.
The lights do not brighten when I throttle up.
The only times the ammeter moves is when starting with the electric starter and when the lights are on - both drag the ammeter down. |

Did you check to see if there is an inline fuse (down by the solenoid). I think they are all fused, but I'm not sure where to tell you to look for it). Other than that, I'd suggest a visit to your local Briggs repair center. Electrical problems are pretty rare for the Briggs engines. |

It sounds like the regulator. Write down the engine model and group information and take it to a Briggs dealer or shop and try a new regulator. They should be around $45. I have replaced a couple and they plug right up. |

I had a regulator go out on an '04 Max II 16hp. Sounds like that is the problem you have. You are right about the connectors but it is easy to splice them into the Max's wires. I think Briggs gets about $75 for that part. |

I guess therein lies the problem. I did buy the B&S part for $70, cut the connector off of the old VR and spliced it onto the new VR. No improvement.
Jerry, That looks like it except the one I got had a round red connector on the red wire. On this picture:
http://faqs.custhelp.com/rnt/rnw/img/enduser/105-AC_DC_test_chart.jpg
the VR has the yellow square connector (3rd from the top on the top part) and the red round connector (3rd fromthe top of the lower part).
Fred, I haven't checked for a fuse because the ammeter needle does move when cranking or the lights are on, but I'll check to make sure.
Thanks for all the help. |

Aubrey, what year machine are you working on. If it is a 1995 or earlier, the fuse is down by the solenoid and an inline one in a plastic case. Newer, the fuse/s are/is in a fuse holder box and are under the dash, on the left side wall (I'm assuming it would still be there -1998 is the newest I have to check). That fuse is between the voltage regulator and the battery. Your ammeter is fine and will indicate a discharge, but since there is no charging going on, it can't show what isn't there.
Knowing what you have done so far, I'm not sure I should hope it is a fuse. |

It is a 1998 model. After spending $70, I'm not sure I want it to be a fuse either. I guess I should have remembered the KISS principle: Keep It Simple, Stupid!
I haven't had time to check it, yet, but I do remember seeing the fuse block under the "dash". |

OK, I checked it and the only fuse I saw was a 30A blade type fuse connected between the ammeter and ignition switch. It was not blown.
Is there another fuse somewhere else? |

Not that I am aware of Aubrey - I also didn't realize that it goes between the ammeter and ignition. The in line fuse is between the voltage regulator and the solenoid (I think).
My book says under trouble shooting "battery not charging"
* Engine RPM too low.
* Inline fuse blown (if equipped).
* Defective battery.
* Loose, pinched or corroded battery ground leads.
* Loose, pinched or corroded battery charge leads.
* Open, shorted or grounded wires between output connector and battery.
* Defective diode (open or shorted).
* Defective or improperly grounded regulator - rectifier.
* Diode installed incorrectly (reversed).
* Damaged battery (shorted battery cells).
*Excessive current draw from accessories.
*Low magnetic flux or damaged alternator magnets.
Hope this helps. I'd be making a trip to the Briggs service center. |
