Hi, I just received a used Scotts 1642 riding mower. The mower sat for a year before I got it. I put a new battery and new air, oil and fuel filters on. Didn't come with a key, so my father in law got a new ignition switch but mower wouldn't start. I noticed an open connection and after some quick research realized that it needed a fuse. The connection comes from the solenoid and then goes to the ignition switch. I thought it was a 15amp fuse. Bought one and put it in. When I turned the key, it promptly blew. I have a voltage meter but don't know where to test (or even if I need to). I'm a general contractor and pretty handy when it comes to wiring but engines have never been my strong suit. Any suggestions would be very appreciated! Thanks! Pat
The switch should have had the the following terminals on the back ( plus some optional others )
B = Battery this is where the wire from the hot side of the solenoid to the ignition switch goes
S = Start / solenoid this is where the wire that controls the starter solenoid starts from it goes through all of the safety switches first but is oft jumped to verify the starter .
M = Magneto this is the wire that goes to the ignition coil it is earthed out to the G terminal to stop the mower.
G = Ground/ earth, usually at a funny angle to all the others aand I will wager was the one you connected the fused wire to.
A = Alternator, the wire from the generator might go here, some go directly to the hor side of the Solenoid.
L = Lights no need to explain that one except it oft gets an AC feed from the generator so don;t mix it up with the 12V Dc from the generator.
The ground wire is generally a short one from a neer by bolt and oft not a part of the plug that fits on the back of the switch.
Are you sure its the right switch, It may look like the old switch but all switches aren't made to operate the same. Make sure you got the right switch for your make and model.
