This is a plate of the TR4 Starter motor and solenoid.



Is there an audible click from the solenoid? If not I would think it could be the solenoid but I am not familiar with the circuitry.

My first idea would be to try the push button on the end of the solenoid. If that does not work I would check to see that current is arriving at the solenoid from the battery, then if current is arriving at the solenoid from the key switch (red/white?) when the key is turned. If current is not arriving at the solenoid from the battery on the main cable, or from the starter button or ignition key follow the chain back to locate the problem. It could be a faulty starter button or ignition key.

If there is an audible click and/or pushing the button on the back of the solenoid has no effect check to see if there is current arriving on the solenoid output when the button is pressed or the key turned, if so check the cable from the solenoid to the starter. If current is eventually arriving at the starter it must be the starter motor that is at fault.
