Default 12v conversion 59a starter solenoid 4 pole. 46 Mercury.

The engine was set up on test stand and ran well using a key start set up without a solenoid. Starter motor is a Titan Quick Start Denso Gear reduction starter. This starter has the built in solenoid.

Have converted to 12v. Negative earth. Have a 4 pole solenoid fitted from Vintage Garage RA0314. Thiis will do a 1 wire start switch (switch grounded) or a 2 wire start switch (switch powered).
The one wire set up has jumper from small terminal to battery 12 positive inlet terminal.
The 2 wire jumper is from small terminal to an earth ie mounting screw.
Hooked it all up and no start?? Using the original start button and ignition switch etc.
With ignition switch on am getting 12 v at coil. Coil is 12v with 3 ohms at primary so no resistor. Have also a wire at power outlet of solenoid to starter motor and another to the solenoid on the starter.
Seeems like the starter button is not wired correct ??

Would appreciate any advice as dont want to fry anything at this stage.
Its ready for the road once I get a new WOF for it. These have to be renewed every 6 months in NZ. Keep to get it on road and clock up some miles on it.
Morris Run In oil for first 500 miles.
