I have a 1994 4016 with the Vanguard engine. I have a very noisy electric clutch which I fear is going to die anytime. I have tried to check the output from the stator. According to a Briggs site, there could be a 20 amp or a 30 amp stator. How can I tell which one I have? I am getting 26 amps out of the yellow connector from the stator, which I think is fine for a 20 amp unit, but would not be ok if it is a 30 amp. I do not want to install the new clutch if I do not have enough output.
