Turn Signal Switch ... Need help with Mark's WCR car Options

[cary]

Good Morning,

I've been laying low after I had isssues with tracing down the electronic issues with the tach in the blue car. The tach was dead. I replaced it with a working silver dot. The only issue seemed to be the size of the bulb holders. Swapped them out, everything seems ok. Am I missing any hidden issues?

But I'm having trouble with the turn signal switch. Turning on the left signal blows fuse number #9. I hope Mike Bellis is around today, he seems to have a good grasp on switch issues.

Here's where we're at:

* Stalk switch for the parking brake lights work with key off. Both sides, all lamps. (IMG:style_emoticons/default/biggrin.gif)
* Light switch turns on the all parking lamps, key off. (IMG:style_emoticons/default/biggrin.gif)
* Emergency flasher works key off and on with the turn signal harness unplugged from the column switch, all lamps (IMG:style_emoticons/default/biggrin.gif)
* Turn signal in the down position works. Both front and back. Seems backwards. turns on the right rather than the left. I switched places on the black/white and the black/green in the harness connector at the switch. Changing them did nothing. I'll deal with that later.
* Up postion blows the fuse #9. After going thru a pile of fuses I went to NAPA and bought a couple circuit breakers for $8 each.
* Next step was to try the switch from my 73. Doesn't fit but everything works. (IMG:style_emoticons/default/biggrin.gif)
* Then I proceed to test out the 75 switch as per Mike's numerous posts. Everything tests out other than continuity between blk/wh/grn and black/green. Zero, nothing.

So the $1,000, 000 question. Do I swap out the 73 wiper switch and stack it on the 75 washer. Will that work ? Will It fit ?
Or tear into the only 75 wiper switch I have?

EDITED @ 6:50 PM
Here's the info I started with this AM.

Nothing from the Brain Trust ................. ???????

Heading to lunch.

Couldn't wait. So I dove into the deep end. Stacked the 73 turn signal onto 75 wiper................... no flames, no sparks no blown fuses. I have turn signals. Even on the right sides. LOL.

But no dimmer ..................

Something for after lunch. Oh yeah, for those that are counting. This is my contribution to WCR. I stopped the clock right after I installed the tach and got it working. When the turn signals stopped working I almost started crying ....................... All I could see was Mark's post on being the first time in 4 years he'd be driving a car to WCR.

Not on my watch ...............................

Can you hear the relay clicking when you toggle the high beams?

75-76 wiper switch is unique. It was sourced from the 75 VW Rabbit. Nothing else is close at this time. It has a lower ridge to clear the housing. 72-74 turn signal can be used with a little work. Plastic holder for washer lines has to come off. Then you can tread it into the metal ones is the column.

Did you make sure your ground is in place on the wiper side upper right corner?

I gave up trying to make mine work with the plastic housing and switched the whole assembly from a 74 using the 75 lock assembly. You can't tell the difference unless you check it close.

Nope. Funny you should mention it. I've been fighting that click for two days. Sounds almost the same as blowing a fuse.

I'll double check the ground strap. I was watching it pretty close. But didn't check when I finished.

Unfortunately I swapped out my column for a tilt and telescoping unit and have not had to troubleshoot a 914 switch. It sounds like you are missing a ground somewhere. The hi/lo relay is triggered by a momentary ground (brown w/white or sometimes yellow).

Start by grounding the terminal at the relay to test it first. Then track down the missing ground connection in the column.

[cary]

Devine intervention.
Came back from lunch and the dimmer was working.

Contact cleaner probably dried out.

When we did Lennies914 car the #9 fuse was blowing just like yours. It turned out that the harness where it goes through from the engine compartment into the trunk to the left blinker was pinched. One of the wires grounded against the chassis. We taped it up and all was good.

Just a shot in the dark!!

[Mikey914]

Found a potential spare. Untested, I'll get to you tomorrow.

[cary]

I've got the testing part down ............ LOL
Thanks ............

Here's what the top of the 75 turn signal switch looks like.


At the end of the day only a couple issues. 1. Turn signal doesn't cancel. Not great, but can be dealt with. 2. The instrument illumination lights come on when the right side is in key off Euro parking light mode. It can be dealt with later.

Now the new question. Has anyone opened up the lower layer of a wiper switch to clean it and been able to put it back together?

I opened up one of my old broken ones to see what the issue was.
The yellow line is turn signal.
The red line is the Euro parking lights.

Don't really understand how one side would work and not the other.

Here's what it looks like under the hood/tin plate.

Oh yeah, short episode of Tool Whore ..................



Oh yeah, the car has an Engman/JWest style fuse panel.

Left is a wire terminal removal tool.
Right is a re-settable circuit breaker

Mark will be adding them to the catalog at 914Rubber. (IMG:style_emoticons/default/smile.gif)

2. The instrument illumination lights come on when the right side is in key off Euro parking light mode.

I found the issue. One of the PO's had tied the wires at the headlight switch from the right parking lamp terminal (58R) (current track 31) to the instrument illumination wires on terminal 58A. (current track 36) We're talking a splice type union.

This created a monster size direct short in the wiper switch. Which melted the switch, rather than blowing a fuse.

[Mikey914]

Again,
Thanks Cary,
I would not have the time to track down everything you are doing.

Some guys should never be allowed to own a wire cutter and electrical tape (IMG:style_emoticons/default/slap.gif)

Ok, whore...

Where did you get the circuit breaker?

[cary]

NAPA, re-settable circuit breakers. I bought one each.
After chasing down the issues with the #8 fuse today. I think I'll get 3 more 7.5 amp ones. I paid $8.05 each.

Rick this is what caused all the carnage. Tied two different circuits together. Which circumvented the fuses. Which melted two turn signal switches, some wiring and an ignition switch.




The taped spots are where they were tied together. They'll get heat shrinked in the am when I get every thing dressing out and tucked back up.
