Regulator 845907

On briggs and stratton twin cylinder engine, start engine up, put engine full throttle, set multimeter to dc volts, check batter voltage. Should be greater than 12 volts. If not find the voltage regulator with 2 yellow and 1 red wire coming from it. With engine still running unplug yellow wires and switch multimeter to AC volts. The yellow wires coming from under the flywheel (the thing on top that is spinning) insert test leads into that plug. Should be somewhere around 20-30 volts. If that checks out fine, plug yellow wires back together. With engine still running at high idle, unplug the red wire from the regulator. Set multimeter to dc volts. Insert one probe in red wire from regulator and the other to the frame or a good ground. Should be greater than 12 volts. If not its the voltage regulator. Remove, unplug, plug new one in bolt in place. Run mower at high idle, check voltage at battery, should be greater than 12 volts. If batter was low to begin with let mower run at high idle for 10-15 mins and recheck.

Take two bolts out of regulator disconnect wires. Replace bad one with new one

Removed the two screws securing the worn regulator, Unplugged terminals, attached new regulator and attached terminals. Bright lights again.

1) Checked battery voltage prior to replacement of regulator
2) Checked alternator output - good
3) Removed old regulator and temporarily connected new regulator to alternator and battery through starter switch connection.
4) Checked charging voltage at battery and it was good.
5) Replaced connectors on both alternator output and and new voltage regulator input to match
6) Reconnected new regulator
7) Checked output voltage at battery and battery was charging.

The fuel pump bolted to the side of engine 2 screws and 3 hoses to remove very easy fix.
The voltage regulator also bolted to engine with 2 bolts a 2 yellow wire connector to the
Alternator and a Single red wire connector to the battery.
After making repairs I cranked the engine with choke engaged as usual
And within 5 seconds the engine fired up it sounded so good to hear run again
Then I used my ohm meter to check the voltage at the battery it read 13.87 volts.
Now engine cranks over much faster and starts every time

Removed and replaced voltage regulator.

Removed 1 10mm screw and loosened the 2nd. Unplugged the old regulator and plugged in the new one. Replaced the removed screw and tightened both.

Plugged in the part and remounted it.
