1965 Continental Doesn't Start

Bill -

My car doesn't start. Nothing happens when I turn the ignition. Battery
has power (lights turn on, windows, signal lights all other electrical
is working). Their is no sound. I thought it might be the starter so I
called Lincoln Land and described what I experienced. I purchased the
solenoid after briefly explaining the problem.

Replaced the solenoid but still nothing. Wondering if I should next
replace the starter or are there other tests to narrow the issue? I
wouldn't call myself a mechanic but I want to understand basic
diagnostics before the pain of pushing the car out of the garage and
having it towed to a shop.

I live in Brooklyn, NY.

Thanks.

The easiest way to diagnose this issue is at the starter solenoid. Have a helper sit in the drivers seat with the transmission selector in Park and his foot firmly on the brake pedal. He then turns the ignition with the key to the cranking position while you test the two large cables at the solenoid for power with a 12v test light. The solenoid should activate and both cables should have power. If they do, that indicates that power is being sent to the starter and the starter should then crank the engine. If the starter does not operate when receiving power then it or its wiring need service. If however no power is detected at the starter cable side of the solenoid, the solenoid is defective or it is not being activated by the starter cranking circuit from the ignition switch. Power should be detected at the "S" terminal push on connector plug at the solenoid with the key and ignition switch in this cranking position. If NO power is received at either of the two female push on terminals of the solenoid you will need to trace the wire to the neutral safety switch and the ignition switch as per the shop manual wiring diagram. Keep in mind that those two small female plug in wires can easily be "crossed in error " at the solenoid and cause your exact problem.

The above diagnostic suggestions are assuming that you have a fully charged and capable battery and that no other unknown wiring problems or misconnects exist. Good luck with the testing and we will have any necessary parts available for you as required.

Sincerely,

1965 Power Issues

Good evening Bill,

I have a 1965 Lincoln Continental Sedan. I am tracing multiple power issues. I lost power to all windows and the entire relay bank located on the drivers side apron. The only thing currently working are the courtesy lights and the clock. I believe the problem could be the circuit breaker panel. I have yet to find a layout of what size breakers are on the circuit breaker panel and what they power. Currently, the two breakers looking right to left have no power. I have tested them with a 12v tester. I have replaced what was currently there like for like and the other three now have power. I have also verified that wire #38 coming off the forward side of the starter solenoid has continuity and 12v. Any help in this matter would be appreciated.

Welcome to Lincoln Land and Bill's corner. Some of these electrical issues can be difficult to diagnose on any Luxury car such as the Lincoln Continental. The difficulty is very much increased if the technician does not have the Factory Service Manual and the "correct" wiring diagram at his side. If you need any of these, please contact George at Lincoln Land and he will advise you how to obtain them.

I also would like to get some more information from you regarding these issues. Did you purchase this Lincoln with any of these faults or did they just appear suddenly? Did they possibly occur after a repair of some kind? Do you know if any wiring or associated parts were modified at all on your car. Much of the power for these failed items originates under the hood at the starter solenoid located on the right inner fender area. An important Power Window Safety relay will be located behind the splash Shield of the Inner Right Front Wheelhouse, you will need to remove the Wheel to access it. It can be identified by its wiring colors according to the wiring diagram. It is a popular fail item and therefore a good item to properly check out electrically. If you were to find a problem with the "constant" 12v power to that relay for instance, correcting that could solve all of your issues.

We believe mostly in testing parts and confirming defects rather than guessing and replacing parts that may not be faulty.
Sincerely,

Bill
