thanks for the info...so far i have figured out that i have a 10-16 amp charging sytem. I have two yellow wires comming into the regulator and one red going out.  I tried to unplug the regulator from the stator put the lawnmower dies when i do that, not sure why? so i checked it plugged in with motor running, on the red wire out of the regulator i have 4 volts of dc current, and on the yellow wires nothing registers, and not sure of that either.

 Hello Chris:

 You can View a Breakdow of the Engine at this Addy http://shop.briggsandstratton.com/BShopProductListingPage.asp?rsvp=0&PARENTID=0& and Enter the Model Numbers 303777 and the Type Numbers 0015 and Click Search. On the Next Page Scrool Down to the 2nd Listing and Click View PDF. This will DOwnload a Breakdown of the Engine. On Page 6 of 22 is the Stator and the Regulator. Check the Stator by Disconnecting it from the Regulator and Checking the Voltage from the Stator. The Stator Voltage should be 15.5 Volts or Higher from the Stator. If this Voltage is Good, Replace the Regulator. If the Voltage is Not, Replace the Stator and the Regulator. Most times when the Stator Goes Bad the Regulator has Gone Bad Also. Most times the Regulator is the Bad Component. Hope this Helps. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck

 Hello Chris:

 Was this Voltage with the Engine at Full Thrrottle? If Yes, then Replace the Stator. None of the Voltage from the Stator should be that Low. I have found some of the Stators that Feed the Headlight Only can Sometimes Show 8.8 to 9.8 Volts. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck
