flasher/turn signal switch ?'s

alright.
i got yet another question.

with my turn signal switch directions.
it says to connect a blue and a black wire to the flasher.

i have a photo of the instructions as well as the flasher itself.

can anybody tell me which wire goes where?
thank you
bill

 

should i connect the blue with the white?
also
should i just run the red wire with an inline fuse to the battery positive post?

where does the hot wire to the stoplight switch come from?

Looking at your harness instruction sheet, Group B step 7 says to connect the purple wire from your fuse block to the turn signal. So the purple wire should connect to the turn signal switch. This is where you need to take a step back. In your picture, I believe you are showing the original flasher, but your new harness includes a new flasher. So the purple wire should come from that new flasher. The other side of the new flasher is already connected to the appropriate fuse.

The old flasher has three terminals. One is the power input, the other two are the [L]oad and [P]ilot outputs. The Load output connects to the turn signal switch, while the Pilot output connects to the indicator lamp in the turn signal switch. It's a little hard to see the details in your picture of the TS switch diagram, but I think I see the black wire connecting to the [L] terminal. If this is correct, then you would connect this black wire to the purple wire from your new fuse block.

I suspect your new fuse block contains a 2-terminal flasher. Can you confirm this? If so, there might be some complication in getting the indicator lamp to work. If there's provision for a three-terminal flasher, you would connect the blue wire to the [P] terminal on the flasher.

Looking again at the harness instruction sheet, Group C step 11 says to connect the small red wire to the brake light switch. So this small red wire should go to one side of the brake light switch (labeled "hot wire" in the TS switch diagram). The other side of the brake light switch should be connected to the red wire in the TS switch.

You should not need to put in any inline fuses or other connections directly to the battery. That's what you got the new harness for.

It's late, so I'm probably not making complete sense here, but I hope this helps.

 

CO64CJ5,

ok
harness small red to switch hot wire




switch red to brake light.




and then purple harness to where on the TS?

i dont see a place to connect the signal switch blue and black wires to the TS flasher on harness



did i read your post right?

you guys are bending over backwards to help me and i REALLY appreciate it!

 

On your original flasher can, red is the power from the ignition switch. Hook it to the acc terminal on back of the ignition switch with an inline fuse. Unless the wire has been cut it already goes there. On your replacement turn signal switch hook the blue wire to the white wire on the flasher can and hook the black wire from the signal switch to the black wire on the flasher can.

Never mind what I just said. I see from your next post that you have a new fuse box with the flasher box on it.

From your diagram of your new fuse box in the other post, hook the purple wire from the fuse box to the blue wire from the signal switch. You can leave the black wire from the signal switch disconnected for now. The only problem you will have leaving the black wire disconnected is the light on the signal switch wont flash..

replacement turn signal switch blue to white on original flasher can.


replacement turn signal switch black to black on original flasher can.

 

that cant be right.
i still have a purple harness wire that is the power feed to replacement turn signal switch

OK, Bill . . .

First, take a deep breath. You're looking at a handful of colorful spaghetti -- don't let it overwhelm you.

Second, you need to make a decision. Do you want to use the original flasher, or the new one in your new fuse block? If it were mine, I would lean toward using the new. However, you might lose the functionality of the indicator lamp in the turn signal switch.

If you pull the flasher out of the new fuse block, does it have two terminals or three? If two, does the socket have space for a third terminal?

If the new fuse block will not support a three-terminal flasher, you have three choices, as I see it:

1. Do without the indicator lamp in the turnsignal switch
2. Add a simple modification to make the indicator lamp work (we can work through this later if you decide to go this way)
3. Use the old flasher to get the indicator to work

​

Tell us which way you want to go, then we'll take the next step.

 

i want to go with door number 1 please...R)





or whichever one i can do myself without having to make 10 trips back to my computer to ask 1000 dumb questions.......

 

OK, excellent choice. You can still take door #2 later if you decide to.

So, connect the purple wire from the harness to the black wire of the turn signal switch.

next?

 

i am writing this down.
and afterwork going straight to the shop and do whatever this thread tells me to.

 

I think we have this one covered.

Yes.

Pretty much . . .

ok
im takin notes here.

 

now i would like to try door number 2

anybody got any ideas for me?

 

Bill,

Sorry for the late response -- I've been away for awhile.

I had to look back through this thread to try to remind myself where we left off. I don't remember now, but it looks like you might have posted an instruction sheet, maybe in another thread?

Anyway, just looking at what's in this thread, it looks like there should be an orange and a green wire which go to the front turn signal lights. These will be "pure" turn signals, that is, not affected by the brake lights. Flipping the switch to either direction will send intermittent (flashing) power to one or the other of these wires.

Also, the picture shows a blue wire leading from the flasher module to the switch. I think this is the flasher indicator ("pilot") in the switch. Connecting this to +12V should cause the indicator lamp to light. Can you check this? Note that there is always the possibility that anonymous posters on the internet could be mistaken, and connecting things to +12V could cause the smoke to be released, so do this carefully. Best would probably be to use a test light to check this -- connect one end of the test light to +12V and touch the other end to the blue wire and see if the indicator light comes on (it could be dim this way).

I don't see that you mentioned whether you have a 2-wire or 3-wire flasher. Can you check this too?

 

OK, I did a little more poking around and I'm pretty sure the blue wire goes to the indicator lamp in the TS switch. All it needs is +12V to turn on this lamp.

A 3-terminal flasher has two output terminals. One of them connects through a heater inside the flasher, the other does not. When the heater reaches a certain threshold temperature, the internal switch contacts close, connecting both outputs to the +12V input.

If you have a 3-terminal flasher, you can connect the blue wire to the third terminal (labeled "P") and the indicator lamp will light when the turn signal flashes on.

If you don't have a 3-terminal flasher, and can't or don't want to get one, an alternative would be to connect the blue wire to the green and orange wires leading to the front TS lamps. This way, if either front TS light is on, the indicator will be on.

But wait! You can't just connect these wires together because then all the lights would flash at the same time. You need some way to isolate them so either left or right can light the indicator, but they won't light each other.

This calls for a pair of diodes. A diode allows current to flow in only one direction, so you can use one to connect from the green wire to the blue wire and another from the orange wire to the blue wire and there will be no crosstalk between the orange and green wires.

A very common diode for this purpose is designated 1N4001. You can get it at Radio Shack. This diode will handle 1 amp at up to 50 volts. It has two wires coming out of it, and one end is marked with a "band". Take two of these and twist their banded ends together. Connect this to the blue wire. Connect the other end of one diode to the green wire, and the other end of the other diode to the orange wire. Use the appropriate crimping, soldering, and insulation techniques.

This way, when the orange wire is energized, current will flow through its diode into the blue wire, but the other diode will prevent current flow into the green wire. Similarly, when the green wire is energized, current will flow through its diode into the blue wire, but not into the orange wire.

Or, you could forget about all this and just connect the blue wire to the same flasher terminal as the black wire. This might work, because the indicator lamp might not draw enough current to activate the flasher's heater. But it will always draw some current, maybe enough to glow dimly. This would not be my choice, but who am I to say?
