Need help FAST !!!!! FIXED !!!!

I'll grab a pic of it for you Thunder Chicken.

The green signal indicator lights both come on and work fine. The fuse isn't popping now. Everything seems to be working fine except the outer two signal lights on the passenger side rear. First thing I'm going to check is under the carpet today, from there..............I have no idea.

Ok, if the two signal lights aren't working that might be sequencer related, probably just an adjustment. As for the dash light problem you were having, I don't know whether to be glad for you or sad: Glad that it's not acting up for you anymore, but sad because you didn't actually find and fix the problem, which means that means you've now got an intermittant electrical problem, and those are the very worst kind...

TC, I wish we would have disagreed sooner. It would have changed the way most of us have been looking at the problem. You are mostly if not 100% correct. I got to thinking about how the sequencer has to work. It is only on one side of the circuit. It is not the load, it is modifying the voltage going to the load. Simply put, it is delaying the voltage going to the multiple loads (bulbs). The ground is handled at the loads. Assuming the sequencer is a sealed unit, the sequencer can not be blamed for a short or bad ground. It can only be blamed for an open on the + side, which is not the issue here.

Correct me If I'm wrong, but I think Vinnie has already found the main problem. The short was at the printed circuit sheet behind the cluster. Could this have caused damage to the sequencer? If that's the case, replacement of the circuit sheet and the sequencer would solve all the problems.

I hadn't noticed that he'd found the printed circuit problem. If the problem is indeed in that printed circuit (and hopefully it is) it would result in a short between the turn signal indicator circuit (which is on the front turn signal circuit) and the dash lights. This kind of short would cause exactly the problems Vinnie's been having with his dash lights.

Since the front turn signal circuit is the fault, it would not cause sequencer failure. It appears Vinnie has two problems. Chances are that the sequencer issue had been happening before, but only noticed it when he noticed a problem with his dash lights and went out back to check what was working. It's fairly likely that the sequencer simply needs adjustment, but I need to see a photo of the sequencer to explain how to do it...

it's possible.. when the problem started, the circuits crossing from the cluster sheet may have damaged the sequential box.. that's actually VERY possible if his inner-most light on the passenger side is still working.. if that's working, than he's still getting a signal TO the sequencer.. vinnie, i think that is your problem with the turn signals, since you found what was making the dash lights blink

I had pulled the cluster and tried the signal, still the same results.

The radio (cd player) still works as it should as well.

I had suspected the cluster to be where the two circuits came together.
This info steered me away from that theory.

It's actually not possible because the problem is in the front turn signal circuit, not the rear. Even if the dash lighting circuit were shorting into the rear turn signals, the sequencer would not be damaged because it only cares whether it sees power or not, it doesn't care where that power comes from. That's why it sequences once when the brake is pressed - it sees 12 volts, it sequences once. The only reason this process repeats with the turn signal is because the turn signal flasher in the dash keeps cutting power and this resets the sequencer.

The only remote possibility that this problem damaged the sequencer would be if the short was into the center or outer bulb circuit, as this would cause power to backfeed into the sequencer's SCR's and could possibly pop them. For this to happen, however, a wire would have to be run from the rear of the car (in particular, either the center or outer bulb) up to the front and shorted into the dash lights. I know Vinnie moved some wires around, but I doubt he did this. And if he's got an older sequencer with relays instead of SCR's even then it couldn't damage the sequencer, since the relays would be open and would simply not allow any power into the sequencer.

ok, so maybe it didn't short the sequencer.. but it's still possible that it's shot. his front signals and inner most tail light signal work as they should.. if his inner-most signal is working, than it shows that the sequencer is getting signal, but it's not sending power to the other 2 sockets.. it's not 'sequencing'

That would make sense. If front blinker is working fine and 1 bulb in the rear is working, the indicator would blink at normal speed. He would not have known there was a problem unless he got out of the car and looked. Most people don't leave the front seat of their car to check the turn signals while they are driving. LOL

I was moving a bunch of wires yesterday. Maybe that did it. I'm going to re-check everything when it gets dark again. As far as adjusting the tail lights, how? Do you mean with the tiny little screws? I'll give it a shot.

When I push the brake pedal, only the inner most brake lights and third brake light come on.

This is why I need a photo of it, to determine the correct adjustment procedure. If it's an older one the engine must be running during any testing or diagnosis of the sequencer, as the voltage may be too low to turn on the relays.

both sides? or just the passenger side?

Thunder is the sequencer a home made unit. Ford units are obsolete as i am told. Not 100%. So where do you get them Thanks.


they sell them as aftermarket kits.. on ebay, i see a lot of them for SN95 and newer stangs
