    Jul 01, 2012 · You can test the operation of the solenoid by disconnecting it from the harness and appling power to it. Apply + to the contact that had the RED wire and - to the contact that had the other color wire (color varies but on your 86 TAB = WHT/RED, TAD = LGRN/BLK). This should energize the solenoid (you may/may not hear it click on).
