Gotta 82 kz750 starter was working intermittently then just stopped, solenoid just clicks when the button is pushed. replaced the solenoid and the battery and am still having the same problems. wires seem to be plugged in right and in good shape. i notice that when i stick a wrench in between the nuts on the solenoid and arc the poles nothing happens but the positive wire that connects it to the battery looks fine. any ideas?
