Tha is a handy piece of info , a lot better than the Briggs Alternator identification chart which being a wall chart is impossible to scan.
Just one thing, only pages 1 to 8 of it seemed to download properly .
Do you have all of it or was it a corruped file in the first place

The 12.6 and 13.4 readings says the battery is charging with proper voltage. May need to check for a drain on the battery when it isn't running. Need to test amp draw when not running. Shouldn't exceed 100 miliamps with key off.

ive tried this with two new batteries.is it possible it wasn't charging because it was sitting for months or years that the magnets were rusty and wasn't charging or decharging cause it seems to charge but it takes forever like five min.my other mower is at full charge in three seconds so I don't think the charging system is right at all taking that long to get a charge

The length of time to recharge the battery will vary with what charging system you have. It sounds like it could be the 10/16 system, but there is also the possibility of the 3/5 system, which isn't any more than a twinkle charger.

If you have the 3 amp charging system, it actually takes 2-3 hours after starting to fully recharge the battery.

I looked at briggs and Stratton but I guess there is three for my motor.the pictures even on zoom I cant tell how many wires are coming from the alternator.mine has a red and black on one plug and gray and black on the other plug.then there is a yellow with a round end ,theres only lights and electric start on this mower why would there be a big alternator.why do they make things difficult

You have the 3/5 charging system. The grey wire goes to a fuel solenoid, the black is the kill wire. The red wire should have a bump above the connector. the black next to it is AC and is for the headlights.

With only 2-3 amp for battery charging it will take 2 to 3 hours of running to fully recharge the battery after starting. Now if the diode, aka the bump goes bad you can have battery discharge when it isn't running as well as not charge the battery. But in the cases I have seen it won't get the 13 plus volts at the battery.
