C-3 Door Ajar re-visited

[Tony Roussos]

I suppose if I were ever asked for advice in troubleshooting, I would now say something like never assume anything and never rule out the obvious.

My door ajar warning light wouldn't come on but very intermittantly for either door. I presumed it was a faulty ground that affected both door switches. For some reason, I ruled out the likelyhood that both switches were bad. They were both bad. I ordered replacements from Ecklers. One of theirs was bad too. The spring broke through the center of the body before I got a chance to screw it back in the door jamb.

I haven't tried to check the factory alarm yet, but I will give the door ajar contact a closer look before I chase my tail again for something more technical.

I hope my experience helps another restorer somewhere, sometime.

Tony On the alarm start with the key switch and test on the back side with a meter to see if it works then the horn as they are the most common areas I have found to need work on the system after the switches which you have repaired. Lyle

Tony,

I've got the same problem with my 69. Don't use the original switches - they are a misconstruction! Use the second generation (76 ->). They got better contacts and are working really fine since a year.

I was wondering if I could do that! I ordered the exact replacements from Ecklers. One broke! The retract spring breached the body, so they're sending a new one. I'll follow your advice the next time I replace these switches. Thank you.
