Question about Ford Thunderbird
It sounds like the ignition system is not sending the signal to the starter selenoid or the selenoid is defective..
MAKE SURE TRANSMISSION IS IN PARK OR NEUTRAL AND THE PARKING BRAKE IS ON BEFORE PERFORMING THIS TESTS.
1.- Try jumping the selenoid's two terminals to make sure the starter gets juice.
2.- Apply 12v to the S terminal in the selenoid, it should engage the starter, if not, replace selenoid, if starter engages, perform next test.
3.- Use a Voltmeter set on DC, place black end on the battery's (-) post and with the red lead, check starter selenoid, one terminal should always have 12v or more and the other one should have the 12v only when the key is on the RUN position. if test fails,the wiring or the ignition switch are defective.
NOTE: The selenoid needs to be grounded to the chasis by the fastening screws, check for clean tight connection.
If you still need wiring diagram of the starting system, let me know.
