Hello. -New guy here. I can't crank my Murray Select 21HP B&S engine. I always thought I was pretty fair at trouble shooting B&S engines, but I'm stumped this time:frown: I've used this mower for years. Shut it down, now-nothing.
Here's what I've checked so far:
12.8V at battery.
good clean battery connection to ground.
good clean continuity to positive solenoid post.
12.8v at solenoid +post to gnd.
no voltage to other solenoid post (even when turning start switch).
no voltage to the starter - ever.
replaced the 4 wire solenoid & cleaned all connections there (including mounting to chassis).
no voltage on solenoid's orange wire (even when switching ignition).
checked seat,clutch/brake, & pto switches (all working fine).
ohm'd wires connecting seat,clutch/brake, & pto to start switch for continuity.
tried another known good start switch.
It's not the fuse as that was removed from the circut years ago.
I'm frustrated & stumped. What am I missing?
I appreciate you advice.
