Question about Ford Thunderbird

1 Answer

I have a '72 T-Bird 429 in a 1 ton Ford truck ('73). I need an electrical diagram because the engine will not turn over - electronic ignition OK, distributer OK, battery OK with power to firewall solenoid. Could it be the ignition switch?

    Thise were the only two things I thought might be the problem. I just needed to know how to test them. If neither of them are defective I will be writing back.
    Thank you.

Hi!!

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.

Good Luck!!

Find yourself a electrical distribution diagram an see where the B+ voltage to the ignition comes from . An you need to be a little more specific ! Ignition system or ignition switch .
Free wiring diagrams here http://www.bbbind.com/free_tsb.html
Enter vehicle info. year , make , model an engine size . Under system click on electrical distribution ,then under subsystem click on power distribution . Click the search button then the blue link's one at a time .
Do you know what electronic throttle control is ?
It should be noted that the ETC system includes a wrench light on the instrument cluster that illuminates when a fault is detected. Faults are also accompanied by DTCS and the "Check Engine Soon" light.
Your best bet mite be to take it to a qualified repair shop.

Ford t bird starts for a few seconds but acts as if it looses ignition is there a start run relay on this model?


With ours, the engine began to run several kinds of poorly around 45,000 miles - lots of misfire, low power, faltering under load, and so on. After getting tons of suggestions and a couple failed "sure fixes" from my otherwise trusted mechanic, I changed out the spark plugs, spark coils, and boots, based on my own research. Since then it has run wonderfully!

I have a 73 ford 1.6 industrial motor. need electronic distributo


Look on E-bay for an electronic CD unit that fires from the original points, but generates about 400 volts to fire the standard coil. My guess is that there is no all-electronic ignition system available even as a racing option. Ford used this engine in the Pinto line of cars from`'71 to `73, and all of them used points and condenser distributors. The points and condenser units work fine if in good order and the point gap set at .025". Hope this gives you an assist!

Basic wiring for 429 engine


You will need to get some kind of ignition system first. I would recommend getting an MSD. It will come with wiring instructions, and it will be all you need to run the motor.
