After going thru most of the wires (total chaos hack-job by the PO) in the front of Shanine's car, and after replacing both motors, all relays and the actual headlight switch, I am presented with a new symptom:
The lights will go down, but not up!
Could this be wiring?
Anybody run into this before?
Any hints or tips are as always appreciated.
\D
-
From what I saw in the front of that car today, normal troubleshooting won't solve the problem.

Torch? Sledgehammer? Crusher? ;D
Redraif had a good idea though. Create jumper cables from Anne's headlight motors to Shanine's and see if they act normal.
I might just do that, if only to eliminate some sources
\D
-
If both headlights move in only one direction, it's most likely not the motors, or the relays associated with them. It's most likely the isolation relay, or the wiring associated with it (if the wiring is messed up).
-
Guess it is the wiring. Tried known good relays, same result
Shanine is getting a complete 1984 headlight harness from a PFF member, so that should take care of it (I'M hoping).
\D
-
Another possibility is the dash switch. You could try swapping that as well.
-
Been there - no change
-
My dash switch does that, if I just push the button to turn them off, they will start to go down then pop back up! I have to hold the switch in the off position until they are all the way down. I said all that to say this: if you already replaced hers and that was not the problem, does that mean you have an extra for sale? ;D

I should be home the beginning of December, looks like I gotta go shopping at "The Dons Garage" when I get home ;D

Hope you sleep soundly. I'll be there with my truck about 3 in the morning.

Bring it!
Goldie sleeps very lightly and usually on the first floor or in the garage.
But then again, why waste your time Charlie? I have nothing that you don't at least have double. ;D

Robert, just saw on ebay, they have a plethora of headlight switches for cheap. Between $ 10 and 16, including shipping.
So add up what it would cost you in fuel to come over to my place and maybe reconsider. ;D

Charlie, you can take whatever you want as long as you take the trash too ;D
-
I never said anything about loading up. I was going to deliver. Besides, I don't want Don. :D
-
That hurt
Setting booby-traps as we speak
-
All in jest, Don. If you weren't a friend, I couldn't have said that. Same way we razzed Tim.

Booby-traps removed (for now), can't wait to see what you deliver - I can provide a wish list ;D

sure I can buy from e-bay, but I would much rather support a fellow club member.......besides, I am pretty good at setting booby traps ;)

Thanks, but been there, done that, found additional help here:

Turns out, Shanine's wiring is totally messed up. I identified at least two bad wires and I'm going with a complete harness swap. It would take me forever to find all the bad wires/splices in this mess, as Charlie can attest to.
\D
-
Yipes... I KNOW about previous owners & the bad splices! Too many to solder I guess. It worked for my hacked up harness... Again, wish you were closer!
-
Offer still stands about German cake and coffee. You just come over and park yours next to Shaninen's for about two hours and when it's time to leave, miraculously, Shanine's will work and yours won't ;D
Kidding asside, her complete harness just came in the mail today. It even included the two-speed fan relay, isolater relay and headlight relays.
\D
-
Nice... my next wiring task is the SLOW windows, radiator switch that does not work, my dim gauges & zero illumination A/c panel
-
Look for bad ground. When I replaced my ground straps, the windows gained tremendous momentum and all my lights got brighter, to include the ones in the dash
\D
-
OK,
I replaced the entire front harness with a known good one for the 84 that wasn't hacked up, but now ......
No ignition lights, no running lights, no cranking, nothing.
Did I foul something up ???
Somethig specific I should check? All fuses and relais are good. Known good motors.
\D
-
Did you re-install the battery?
Sorry. I couldn't help myself.
Maybe you'd be better off letting Anne fix it.
Oops. I did it again.
I can come by tomorrow and assist troubleshooting if you'd like (for real). ;D
-
Coffee and cake can be served ;D
You wouldn't mind? Always appreciated and welcome.

Name the time.
Coffee is good!

I'm home all day, your call

Big shout-out to Roger! ;D
Thanks buddy, you da man!
update with all the issues Roger found will follow
Lights are BOTH working now (on/off/up/down), as are all running and rear lights, and no more smoke coming from the dimmer!
\D
-
First symptom was that neither light would go up
Second symptom was that after turning on the headlights and back off, they would only dim, but not turn off
Third symptom was that when turning the dimmer switch all the way up, it started smoking
Replaced entire harness and relays (<Don)
Found that the PO had soldered the orange and red cables together at the light switch
DRL in the front wouldn't work
One motor clicked, other one: Nothing (Thats why the battery was drained)
Other than that, same symptoms as mentioned above
Took out the dimmer transistor from under the dash and cleaned it (<Roger) No more dimmer issues and lights would shut off
Ran jumper cables all over the place (<Roger), I lost track after about the third jumper and just sat in a corner and drank coffee, as I was totally lost! ;D
Checked all connections, cleaned one barrel connector (<Roger), motor went up and down, but clicked
Replaced both motors, replaced all connectors from a known good motor that has bump-stop issues with the connectors from a known bad motor (Cover with the 3 screws)
Cleaned sockets on the DRLs
TADA! All working again!
Thanks again Roger!
So Charlie, I know have 3 first generation headlight motor candidates for rebuilding and have ordered the rebuild kits for two of them.

Loose battery cable?

Nope, far from it

-
I don't know what happened. I clicked on the "latest post" link & got the page before Roger helped you fix it.
Checked the thread after I posted & realized it, & deleted my post. You were just too quick...

OK, it seems that I am cursed with these 84s!
After getting Anne's 84 figured out and more or less fixed, Shanine's is now starting to baffle me.
Roger came over and got the headlight issues straightened out.
Today we had a police officer come and verify the VIN for us so we could go and register the car before Christmas for Shanine and.........
.........won't fire up!
No fuel from the TBI and even if I pour alcohol down the TB, won't fire up. Have fuel with pressure behind the fuel filter, pump runs just fine.
I've checked all the wires and fuses and have tried three (3 !!!) different computers. It just cranks and cranks but nothing.
???
Anybody have some advice?
\D
-
I recall reading somewhere that if the tach doesn't move while cranking, it is a specific issue, or a symptom that indicates the cause.
This is the issue here, Shanine's tach doesn't move while cranking.
Any ideas?
\D

I think if the tach doesn't move, it's the ignition module.
EDIT: Might just be a loose wire on the distributor...

Cleaned the contacts on the ign-coil, now the tach responds, but still no spark or fuel
Edit: Nix that remark, tach is NOT responding
-
Replaced ICM and pickup module, still won't fire up
Have spark now but injector won't pulse
Also not getting the 5 V to the TBS
So, shorted pin 10 & 15 on the white ECM connector to the cig-lighter, as it was not getting constant 12 V on those, which somehow get the ECM to shoot the 5 V to the TBS
Now she fires up and runs.
Can anybody think of why it's not getting 12 V constant hot there, and any ramifications of hot-wiring it?
Thnx
\D
-
Possibly intermittant power from the ignition switch.
I'll have to look at the schematic again.
I wouldn't 'hot wire' it tho. That may present a hazardous condition.
-
Thanks Roger.
I will actually follow your advice and not hot-wire it, because .......
........FOUND IT!
Fusible link was cut out by the PO and he/she/it spliced a wire that goes from the alternator directly to the distributor (84s only), then disappears into the harness back to the ECM
Shielding right under the TBI had come off, hence blank wire shorting out against the engine block.
Tagged and running again! ;D

One issue remains:
Driver's side turnsignal doesn't blink. Emergency flashers work on all 4 corners, but only passenger's side turnsignal flashes.
Relay?
\D
-
It could be the flasher. The turn signals and emergency flashers have separate flasher relays, so while one system shows that the bulbs are good, the other might make you think a bulb is bad.
-
Are the left and right signal relays identical, or is it just one relay for both sides?
And where is it/are they located? Behind the driver's side on the firewall?
\D
-
The turn signal flasher should be located on the steering wheel support, left side, near the fuse panel.
The emergency flasher should be near the blue dingy box on the passenger side.
They are interchangeable so you can troubleshoot by swapping them.
-
You could always use hand signals. Remember those?

Yeah, but that frostbite during winter months really gets to ya!

Had fun working on this one.
Probed and probed with the meter.
Then read the wiring diagram for the lights.
Did you know that the front marker lights are wire in series ,power in to marker lights then out to the front marker/running light then to ground.
That said, if the ground on the front dual element light is bad,..it will back feed through the power side of the dual element bulb, up the power side of the turning light and do all kind of wierd stuff.
We replaced the front left dual light socket and all was fixed.
I love trouble shooting electrical issues!
I miss doing that...did it for 20+ years now I embroidery and screenprint?...
Let me know if you'll need anything else.

He does use hand signals. Every time he does, it becomes a Fight or Flight situation. :)
