67 Turn Signal Switch

Re: 67 Turn Signal Switch

Steve , where and how do you do the "grafting"? Solder or use inline connectors? Would save a lot of time if practical. Any photos from you or anyone else who has spliced the new switch to the original wiring?
Thanks

Re: 67 Turn Signal Switch

William, I did this about 10 years ago. I cut the wires in a staggered fashion close to the switch end with about 1-2" per stagger. I then used some small lengths of shrink tubing over a carefully soldered parallel joint to minimize the connection "bulk". The splices wound up inside the cone shaped piece just below the switch housing and before the wiring entered the flat black cover on the column.

Re: 67 Turn Signal Switch

Steve,
Thanks, but what's a "parallel " solder joint? Don't you twist the wires together as usual before soldering or is this a different technique??

Re: 67 Turn Signal Switch

A parallel solder joint is as follows:
1 Carefully strip the insulation from each wire about 1/4"
2 If the wire becomes frayed twist the strands tightly back into a uniform wire
3 Carefully tin the wires. DO NOT leave a gob of solder on the wire. The wire diameter should not be noticeably increased
4Lay the tinned wires parallel and touching each other and heat both to melt the solder

Before you solder each wire don't forget to slide the heat shrink tubing over one of the wires

5 Slide he heat shrink over the solder joint and heat with a heat gun.

If you are a novice solderer, I'd suggest trying this on some scrap wires to learn the "art".

The whole idea is to make the solder joint diameter as close as possible to the original wire and insulation.

Re: 67 Turn Signal Switch

Just looked art a recent Eckler's catalog and they feature a "'64-'67 turn signal switch actuating cam "separate from switch. Haven't checked if other vendors sell same thing. Will this correct my problem with my having to hold turn lever town to get turn signal to blink without my having to replace entire switch and associated wiring as a PITA? Previous posts say '67 cam is different from others and not available. What say experts?
Thanks

Re: 67 Turn Signal Switch

SHEE-MAR lists the turn signal switch and cam as unique to 67-68 Corvettes. You can purchase a complete switch or just the cam. They are probably the vendor for the Corvette vendors.
You can find them at SHEE-MAR.

Please provide a link to the item.

Re: 67 Turn Signal Switch

Thanks, Steve.
Do you think replacing just the cam, which will be much easier than replacing whole switch and wiring harness, will cure the problem I describe: I have to hold the lever down to make turn signal blink; when released, lever does go back to neutral position.

It's a hard job but somebody has to do it....... Wow they gut alotta stuff in that catalog.

Okay, okay.....here is the link to the Eckler's part.

I just love Eckler's descriptions.....Every part, a nut, abolt, a switch, has this text in the description....."has been manufactured to original factory specifications using today's modern manufacturing techniques. You will find the fit and function will work superbly for your restoration. In addition, using a reproduction turn signal switch actuating cam from Eckler's will add authenticity and value to your Corvette."

hmmmm, pretty red color just like the originals. Certainly, the Judges will like that and guarantee authentication.

You are still going to need to remove the entire switch to replace it as the pin has a barrel that needs to be peened over. Best to do it at a benchtop.

Re: 67 Turn Signal Switch

Probably... there are plastic "tangs" that keep the switch in the turn position and are released by the rotation of the steering wheel cancel cam. These "tangs" are probably broken. If you look at the SHEE-MAR photo of the switch cam you'll notice 2 "hooks/tangs" as part of the cam

Re: 67 Turn Signal Switch

Doesn't matter if it's day glo orange or purple, judges don't judge things that aren't visible, as I read it. Reckon super glue could glue broken cam back together or is it one of those kinds of plastic that don't glue well?
