wiring diagrams

Where can I find the wiring diagram for a 15 horse B&S model 28N707, and a 18 horse B&S model 422707.
Thank you
Jack

I don't believe there is such a thing.... these engines don't have wiring harnesses in them or anything, just a couple electric components with plugs. The diagram usually goes with the equipment the engine is mounted on. What are you trying to figure out?

I want to know where the wire from under the head goes to keep the battery charged?

A common place to hook this wire is the large post on the starter solenoid with the positive cable going to the battery.

BUT,

Do NOT cut the little pin connector off the end of this wire to hook it up, There is a diode next to this connector that keeps battery voltage from feeding back to the stator and burning it up.

Get the proper connector to plug into this wire then extend to the needed length to reach the starter solenoid post.


Good Luck

Any Briggs dealer will have or can get a wire pigtail to plug into the pin connector on the stator.....

Valves worn out of adjustment, This causes the mechanical compression release to not work properly.


Adjustment procedure;






Good Luck
