Hello, I have a riding mower with an 18hp briggs twin II, I have replaced the solenoid, Ignition switch and the wire from with igntion switch to the solenoid, After that the mower started and ran fine, Now if I try to start it there is nothing, I have metered out all connections and they seem fine except for the pos. post on the starter, It shows a direct connection to the chassis ground even after removing the pos. wire from the battery from it.. seems odd to me?
