8HP vertical briggs

[jbruch694]

I just recently acquired a really crappy riding mower of unknown make, with an 8 HP B&S engine in it. it seems to be quite old, but without even using starting fluid, i got this thing running that had been sitting outside for 5 years. It has a 12 volt electric start, and a charging coil, all that good stuff. it is a vertical shaft, but I do think i can make it work. my question is, where could I find a wiring diagram for this? I would like to figure out how to wire my own starter and headlight switch setup, without too much trial and error. sorry for the crappy pic quality, who woulda thought the iphone 3g would have such a crappy camera?

well the starter just use heavy gauge wire from batt to heavy switch to starter post, the charge coil i think just goes to batt with switch so i doesn't drain the batt, headlights just wire from batt
need pic of charge coil connector there's different types
(usually has a 5 pole switch and solenoid)

You need a solenoid to run the starter. Probably a good one on the mower.

the key thing has an off, run, run w/lights, and a start key position. it looks like its just one wire coming off the charge coil, that goes to the harness that attaches to the key switch thing. so basically, to build my own less crappy and complex starting mechanism, i need a switch between the charge coil wire and battery, between the spark plug wire, and for the control switch for the starting relay?

the charge wire will go to the battery with switch in middle
the starter needs heavy duty switch or relay
the kill switch needs to be hooked to the little tab on the mag then to a switch to ground
