Engine will run when jumped @ solenoid but switch does nothing but turn on lights. Switch does have to be in on position to jump @ solenoid. Switch tests as good…wires are good. What else could it be?

Hi, Have you checked the earth (ground) connection to the solenoid coil? Power for the solenoid comes through the switch (from the solenoid contact terminal - the same terminal that the battery lead connects to, not the solenoid contact terminal that connects to the starter motor) to operate the solenoid. As you said that the switch is OK and have replaced the solenoid with a new one then the problem is either the wire to the switch from the solenoid contact, the wire to the solenoid coil from the switch or the earth connection to the solenoid coil.

The solenoid. Go to your local home improvement store or lawn mower/tractor store and get a new solenoid.

Motor won’t turn over for a number of reasons. all must be eliminated battery issue - dead or high resistancesafety switches - clutch, seatbad connection - corroded, loose, broken on battery to starter or in ignition circuit.ignition switchstarter solenoidstarter
