I have a 95 Simplicity Coronet hydro with a 12.5 hp B&S it dropped the intake valve before I bought it. I have since repaired that and have used the unit a few times last year to mow. The previous owner told me he had a problem with the key switch and has been using a wire to supply power from the battery to the starter and that worked ok. I have since replaced the battery added a battery tender and replaced the key switch and solenoid, and nothing improved. I have started to go thru the wiring and found a few places where the wiring insulation got chaffed. I repaired the damage and it still won't crank with the key. I started checking all the plug connections in the harness looking for something loose or damaged. Now other than repairing the insulation that I found damaged I haven' t changed anything and now it won't even fire with jump starting the starter( it cranks but doesn't fire) there is a part next to the solenoid that simplicity calls a module. About eight wires terminate into this and they are encapsulated in silicone. It has like a 6" long wiring harness attached to it with a quick connector. I'am not sure of the exact function of this part or how to test if it's bad. I do know that it's about $60 from the dealer and would like to know if it's bad before shelling out the money. I might be overlooking something, the coil wires on the solenoid are getting power but the solenoid is not transferring the power from the battery to the starter to turn the motor over. Any help would be appreciated.
Thanks
