Hey All,

My son has a clean 1982 5th Avenue with a 318. He was on the interstate, flipped on his turn signal and the car immediately died. We trailered it home. When you turn the key to crank it, it does nothing. It is completely dead. Put in a known good battery and even jumped it with a truck. Still dead. The interior lights come on when you open the door.

Ignition switch?

Thoughts? Hard to change this switch?

Try checking the neutral safety switch. Also try jumping the starter relay.

I would bet more on a blown fusable link or amp meter.

are the interior lights working? any of the accessories?

should still be a starter relay, can you bridge that to see if it cranks?

The interior lights, headlights, dash lights, flashers and blower motor do work. When you put the key in the ignition it chimes.

The turn signals now do not work. It died last night when he turned on the turn signal. When you try to start it, its as if it does not even have a battery in it. Wipers do not work now. They are on the turn signal stalk.

We have not performed an under hood diagnostic yet.

I would also look at fusible link(s) and look at all the connections under hood between battery and firewall. There are some slip together factory connections to check for poor connection etc.

You have power thru the fusible link/thru the ammeter/thru the welded splice & to the headlight switch at least. More than one issue I am thinking. seperate/reinstall the bulkheads and the st col pull apart connector as sometimes this is enough to restore continuity on them. see if the yellow "ign" wire at the starter relay is hot when someone turns the ign key to "start". grab your VOM. EDIT with more thought I would start with the turn signal pull apart connector, cuz that is where it started, & it likely has the ign sw feed.

So basically nothing that gets 12v power when the ignition is on is working. If you want to see the motor turn over you can disconnect the brown wire off of the starter relay and run it to the positive battery post. This will bypass the ignition switch entirely and engage the starter.

From what this sounds like it is either the ignition switch itself or whatever is supplying the power to it further up the line. I'm at work right now and don't have access to my service manual. I can look tonight, but won't be home until late.

The ignition switch itself isn't hard to pull out. It's mounted on the column about halfway down and is engaged by linkage from the key. You can drop the column down without much fuss if you need more space to work (it doesn't need to come out of the car).

As RapidRobert wrote, it's not the fusible link, because you have power, otherwise you wouldn't have any lights, etc. It would be like there was no battery in the car.

MarkM gave some good advice on the ignition switch. Run your hand down the left side of the column and find the ignition switch and see if it's loose. You'll have to remove the plastic cover that uses plastic press ins to fasten. See if the switch moves up and down, even a little. If it does, try moving it while turning the key to start car.

Thanks for the replies. I hope to look at it this evening before the winter gets here in the morning.

Sounds like ignition switch or a fusable link/fuse if it just suddenly quit when the turn signals were activated. Also check the plugs off the battery, there should be 2.
It wont be ammeter, full power doesn't run through it.

Check for popped fuses. Check for shorts in the wiring in the column, start with turn signal switch. I had an 85 Ram 1500 blow fuses when I went to use the horn. Turns out the horn contact button from the turn signal switch was wearing away and depositing a layer of graphite dust across the top of the connector block for the wiring on the turn signal switch, causing an intermittent short. May be a long shot but you will probably have the column apart when you troubleshoot this. Not sure what year they changed from a brass roller to a graphite button in the turn signals.

Got the steering wheel off. Not seeing anything broken.

Thanks for the replies. Will be checking and report back what we find.

Did you check the wiring plug on the steering column under the dash?

While the wheel is off you can check for power up there with a meter.

With the car being outside and near 0 temps, we have not done much with this.

My son said the engine will turn over if he jumps the starter with a screw driver and the key on.

He did get the wipers and turn signals to work. One of the wires to a fusible link on driver side fender pulled apart.

Still cannot get the engine to turn over. We will keep checking the wiring.

Thanks for all the help.

Before I went thru trouble of pulling the wheel, I'd check the ignition switch located down the column left side. As I wrote earlier, if it loosened up over time, it can move around when you turn the key. You may be able to hold it in place, and turn key and get car to start. Then you'll know you just need to tighten it down, or replace.

Try holding the key in the start position and move the shifter from park to neutral slowly. It could be a shift linkage adjustment issue.

The yellow wire on the starter relay does not have power when trying to crank the engine.

We replaced the burnt fusible link with one that has a replaceable fuse.
The wipers, turn signals now work.

Took bulk head connector apart and it looks excellent, almost like new.

Tried jiggling shifter while cranking and got nothing.

Replaced starter switch on top of column, nothing.

With key in the run position and jumping the starter with a a screw driver the engine will turn over.

there is an open somewhere inbetween the "ST" (start) terminal on the ign switch out to/thru the bulkhead & out in the yellow wire to the starter relay "ign" terminal. Start at the ign sw (or the bulkhead) & see if the specific bulkhead terminal in the firewall half is hot while cranking & work upstream or downstream from there. unless there has been too much amperage (somewhat rare) that has burned up the strands or all broken strands from too much flexing (extremely rare), wiring goes bad at the terminals/connections.

All of the fusible links along the driver side fender have going into and out of them now.

Where does the yellow wire on the starter relay get its power from? Should it only have power during the cranking cycle?

(1) It originates from the "ST" terminal on the ign sw. (2) yes. Start at the bulkhead & work upstream (back to ign sw) or downstream (out to starter relay) for the open
