4-way flasher / wiring issue

[jdconnel]

Here’s a fun one…..
I started installing new bulbs where needed in my project, I have as follows:
Rear lights on. Rear blinkers work (both). Brake lights work. Front lights on both high, low, and running lights. Front blinkers left and right both work.
Now, when the 4 way button is pushed, I get 3 blinkers. Front passenger, and both rears. Nothing on the driver side front. But as stated above, it works as a blinker…..

Not to worried as I need a blinker more than a 4 4-ways. 75% is a pass  still and interesting problem. Bad bulb some how?

4-way button? You got a button? I'm jealous.

Try pushing and pulling the button a bunch of times, one of the contacts is flakey. You could also try spraying it with contact spray if you can find a place where it can get inside.

err. lever. whatever that thing is in the glovebox that makes things click and blink

I would think that it would just activate the blinker cans? Which is strange, becasue isn't there left and right, not 4 independant?

Heres what ya gotta do. Ck. the circuit from the switch to the
socket. A testlight will do. Then if you got power, make the grounds
good.

The way it works is power from the 4-way flasher goes into the switch. The left-front, right front, and brake lights also go into the switch. When the switch is flipped it connects them all together. See if this post-it makes sense:




And here's a pic of the in-dash button style from a '68 F100.

Looks just like the one on my dash. Oh, it works.

Bragger.

If the glove box toggle original then?
It looks nice in there, and I think it says flasher on it.

[68F250]

Yes the glove box toggle is the most common style.

If it's bad, try to find one used. Here or on eBay.
NPD has them, but they want $191 for them!

Well, I took the switch out. Seems ok, but the back contact plate is falling off.... so it seems I have my answer. Best I can do is get 1 light to flash now. I can prob fit it with enough patience, but if someone has an extra to sell off / part out, PM me.

Thanks,

So you have the glove box toggle switch?

[kaptnkaos]

I had a bad one in my '68 I was able to find one at the wrecking yard for $5.00.. it works great... thats alot better than $191... even if i gotta go back and find another one for $5.00 sometime in the future.

[jdconnel]

Yes. Glove box toggle flyboy.
From what I'm finding thay were also used in mid 60's Mustangs.

Mustangs, Galaxies, Fairlanes and trucks they were all in the glove box in 67. Even my 68 and 69 F series have them there if installed.

The drivers side front ties to the flasher at connector G it is wire 3a from the flasher and it hooks to wire 3 turn signal front at that connector. Even though this is a 70 diagram the flasher circuit applies.
