Re: Drivers side door ajar short

Mark,

Please be much more specific so we can help you...... You only specified a "blue" wire, and that it's a ground. Ground wires are typical black, or black with white tracer.



A short is defined as 2 separate electrical circuits erroneously tied together.

?'s.....

1- What function is affected by this short? EDIT: I see now that the SUBJECT LINE states the function, "Door Ajar"

2- What are the circuits that you're seeing that are shorted?

3- Where is the blue wire coming from?

Rich
PS I'm on the road for the next several days but will check in on occasion. And I don't have access to a 1972 wiring diagram either.

Does anyone here have a page of it to post here so I can look at it?

Owen,

I'm sitting in a hotel in Harrisburg, PA, windy and cold outside. Heading back south for warmth. I'm bored.

Now I have something to do!

Thanks,
Rich

Good luck!

All done.....

Mark, Yes both Ajar switches use Black and Lt Blue. The lamp is tied to power and the switches complete the circuit to ground when door is ajar. But they made a mistake on the Lamp image. They show Lt Blue and Pink tied together. It cannot be that configuration as that would create a dead short between IGN power and Ground when the door is Ajar. See below hen scratching.

Here is the original diagram showing the lamp wiring error.

I'm on the road but iirc, it may simply go to the courtesy light circuit. But I'll look at the diagram later to see If it's relay switched.

Thanks Rich. I appreciate it

Re: Drivers side door ajar short

Rich, for the white wire, where does that attach?

Hi Mark, Last night I looked at the schematic but couldn't find reference to the alarm. Then had to get some sleep.

Was that a option in 1972? If so, maybe the Service Manual has it.

But iirc, isn't the ajar switch 3 terminal? I repaired one on a '69 about 5 years ago but forget what went where.

P.S. Still on the road, in SC/GA border for a pee break and a coffee replenishment, and saw your post. If no one gets in here to help, I'll dig into the books when I get home tonight.

Re: Drivers side door ajar short

Probably not. It has to go through a relay or it'll trigger the alarm any time you put courtesy Lights on via door buttons or headlight switch.

Check AIM for RPO xxx Alarm maybe?
