Loader Starter mechanism Kubota R400

[Washburn]

I am looking for information on the nature of the low current solenoid which closes the high current circuit which operates the starter motor. The current situation is as follows: When turning the key to energize the starter there is a clicking sound but the starter does not turn. Any thoughts would be appreciated.

A followup to the above. The starter mechanism of the R400 is nicely designed with the apparent weakest link the copper contacts responsible for completing the high current circuit energizing the starter motor. These replaceable contacts appear to wear out before other components fail. In my situation they were replaced from an old starter with the only problem the hum bug of removing and replacing the starter in tight quarters.
