1971 Mark III Questions

Hi Bill -

My 71 MK III only runs with coil jumped out to positive. Runs when trying to start but dies when key is returned to run position. Classic case of coil resistance wire failure most likely BUT Where is the Resistance wire on this car? I'm told its under the dash but cannot locate. Can you help me sir? Also looking for a radio guy to fix my AM / 8 Track. Thanks!

John

Hi John -

If you want to locate the ignition resistor wire, it is located inside the harness under the dash and fed from the ignition switch as shown in the wiring diagram. Assuming that proper under hood tests were already done on the ignition feed to the coil from the resistor wire splice, you should then make tests to find out if the ignition switch is indeed sending 12 volts out to this resistor wire with the key in the run position. This necessary diagnosis is performed with the use of the correct wiring diagram and Shop Manual in order to "prove out" the ignition switch and avoid cutting into the main under dash harness if the resistor wire is not faulty. Do you have the correct wiring diagram and manual for your Mark??

We should have a good working AM/8 track tape unit in stock if you would like to replace your present unit.

Sincerely,

Bill

Just wanted to thank you and your organization. From my first Blog question (Thanks for the quick answer) you have helped this project move forward. I ordered the manuals and wiring diagrams and fixed a lot. Windows, Coil Resister Wire, Charging Circuit Fuel Pump and AMP Guage. You also helped me with direction on a carpet issue. Many thanks from a new customer !
