Title: SeatBelt Interlock Problems.
Post by: rdtimmjr on July 19, 2004, 07:57:15 AM
The seatbelt interlock system  in my 74 4-speed sedan activated with buzzer and dash light at a stop light yesterday while out cruising.  :o  Since the system seems to working well it won't start without pushing the red restart button under the hood.  Anyone know of any real quick way to disabled this marvel of an engineering system and turn off the warning lite and buzzer and allow normal starting.  I am real lazy and didn't want to have to go through the wiring diagrams and troubleshoot it myself.  Thanks for any help.

ohman, no replies,  guess what I will be doing at first light,  my great little red Pinto cruiser has got to be able to go without such goofy happenings.  I guess I will have to get out the electrical diagrams and the Crayolas.  Thanks for the views.

Hehehe.

There should be a wiring connector on the floorboard under the driver's seat (you may have to remove the seat to actually get to it). This is what connects the seatbelt sensor to the rest of the electrical modern marvel system thingy. You may have a broken wire telling the system your seatbelt isn't fastened. You may be able to jump the connector (completing the loop and telling the computer your belt is always fastened). Perhaps just totally disconnecting it will solve your "bells and whistles" problem. Start there.

Oh, and would you like to borrow my red or blue crayon?

PoisonPinto, thanks for the reply.  I wandered through my yellowed wiring diagrams today and now all things are fine.  I left the seat connectors unhooked when I put in new carpeting so I already knew that wasn't the problem.  The symptoms indicated the transmission switch wasn't the problem as the buzzer and lite warning only occurred in gear.  Probably my problem was a bare ground in the retractor connector wires or seat wires as I jerked around on all of these today without really figuring what was the problem was and now El Pinto is a  happy go-lucky driver again.  
For future reference on the 74's it looks llike both the retractor connectors(my retractors are still connected)  and the seat connectors can be left disconnected.  The short to ground when the switch is closed is what completes the circuit through the warning lite and buzzer prevents the starter relay from activating so if the switch is disconnected this can't occur.  Pushing the override button brings juice to the relay from another source and the relay will be activated(starter engages) for one cycle, however the magnificent warning features still work.  As I mentioned this is a wonderful engineering marvel created by Ford because of the mandate by your Federal Government in the 70's.  
By the way, I from KY so I bleed blue, but I prefer a red crayola and Pinto.

Good thing I didn't ask if you wanted to borrow my orange crayon....

Pretty funny, PoisonPinto,  I'm also the proud owner of an orange 77 Pinto "Woody" wagon.
