Yes, or just a continuity check with a VOM. Should be closed in neutral and open in any gear. Shift through several times to make sure it is not intermittent. But, that checks the switch, and you need to check the diodes also. Page 17-9 of the FSM tells how to check the switch, 17-12 shows the diodes.Can the neutral switch be tested by applying 12volts and a bulb to it. I think it is just a switch to ground.
