The Stovebolt Site Forums The Shop Area The Electrical Bay Another blinker question.

Hey guys, since about 4 years ago, the blinkers have been acting funny, but now they dont work at all.

The blinker switch on the steeringwheel colum used to have a green led light on when ignition was on, now it doesnt. It used to flash red as the blinkers flashed, but that doesnt work either. So no I have no turning signals.

When we took the car to Holland, they put some european taillights on them with position light, brakelight and turnsignal light (three diffrent bulbs). My question is, how was the orginial wiring, and how should i use the multimeter on the main switch? i want to know if its the wiring or the main switch.

I replaced the "heavy duty flasher" relay thingy, but that didnt help. So anyone knows what to do next?

Check your main power source to your blinker system. Sounds like you have no power.

allright thanks,

The weird thing is that it became worse over time
first, it worked like it should
then they wouldnt flash, only turn on until i switched them off,
and then the would only turn on one flash but wouldnt flash repeatedly, and now nothing.

But ill check main power wiring, i also searched here for a wiring diagram but couldnt find it, but i thought i'd seen it on these forums before.. Well i'll search some more.

I'll keep you guys updated.

Check to make sure it's not just the pilot light.

That would mean the signals are working but the light on the switch is not.



If the whole system is not working look for a fuse holder off the switch and check that the fuse is not blown.



Can you post how many wires come off the switch? Any markings?
Picture?

Sounds like a bad flasher but you've changed that.
Your new flasher may also be bad.

No its not just the pilot light, although before the red light was always on when ignition was on, that doesnt work now either. Also the green pitlot lights showed correctly what was happening with the turnsignal lights...

Fuse was still good. Ill post pics when im out looking at it again.

Btw, i placed a low bid on a new switch, and i won it! so thats nice, if i dont get it to work i can replace it, otherwise i've got a spare. So we'll see what i can find.

It sounds like your blinker could be dying. I am basing that on how it failed in stages. You can hook up a blinker module with a light and power source to test it.

You might check the lights. If one or both are burned out there will be no current to drive the flasher. Also look for a bad ground, they can cause all sorts of funky symptoms. The reason others have asked which switch you are using has to do with how they are wired. For example, mine is a 4 wire switch. It needs separate turn signal lights. Not integrated with the brake lights. Other switches will integrate with the brake lights and they are wired differently.

@Truckernix
Allright, i thought that too.. I'll test that.

@Steve_H
All bulbs are good. I'll check the wiring and post a pic of the switch so you know what im talking about. I dont recall them changing the switch and i'm quite sure the old lights (which i dont have anymore) had turnsignal and brake lights on the same bulb. But i'll try to find out a bit more and come here again!

Allright lets see..

I've got this switch: Signal-Stat 900
But i bought this one now, so i might replace it.

Anyway, something weird is going on.

1. Someone cut the black/grey wire from the switch, because the taillights have separate bulbs for brake light and seperate bulbs for turn signal. So that i understand. (But brakelights dont work, where is the switch? Dont see one on the brake pedal nor the main brake cylinder..?

2. Well anyway the weird thing is, that on the left side, everything works well, except that the turnsignal doesnt start to flash untill about 2 seconds after i turn the switch.

But on the left side it becomes weird.
With positionlights on, and starting to use the turn signal it flashes realllll slow. Also when it flashes, the brakebulb flashes while the positionbulb turns off. Hard to discribe..

So i think someone has done the wiring incorrectly. Plus that they've soldered instead of using real conectors.

______________________

So i was thinking, im going to change all the wiring to all the lamps. Headlight, turn signal, brakelight. EVERYTHING.

But here's my "problem".

the wiring from the turn signal switch to the lamps is easy. I know how to do that. But i took a quick peek at the light switch on the dashboard. And there's still the original wiring with the weird cottonwiring. So i want to replace them aswell.

3. The light switch has two modes: parking/position light, and headlights. Then the switch on the floor switches hi-beam/lo-beam.
Its dusty as crap, so i cant really see, but I found an image on the webs, this one. Is that the right one?

4. Then..
Do I understand this correctly?:
Headlamp -> power for highbeam/lowbeam
stoplamp -> power to brakelightswitch?
tail lamp -> normal position light on tails.
parking lamp -> small 5 Watt bulbs in headlights?

Im sorry but its a bit hard to explain everything in english.. hope you guys understand and can help me..

THANKS!!

Edit
Okay, the turnsignal light does work as it should when the normal lights are switched OFF. Also i found the brakelight switch, i was a bit blind earlier today i guess But still, brakelights dont work.

Just to make things more confusing. The park lights are off when the head lights are on. Power from the brake light switch runs the turn signals. So that must be run before the switch to the turn signal unit. Head light power goes from the head light switch to the dimmer switch. Then to the head lights. This can all be tested with an Ohm meter.

The headlamp switch you linked is not the correct one for your truck.




Head lamp switch.

Keep in mind
Tail lamps are a separate circuit

Can you post how many bulbs you have in the rear?

Trace the wires off the stop switch off the firewall, where are they going?

Alright, thanks!

Thanks DADS50, its almost imposible to trace the wires from the switch because it has become one big chunk of dust.. I dont really want to touch it untill i know how to connect everything later again.

But about your link to the headlight switch:
Whats a dome lamp? the lamp on the "ceiling"?
Why are there 2 empty connectors?

Right now there are 3 bulbs left and 3 bulbs right. But my new lamps have 2 bulbs on each side. So thats why im trying to figure out whats going crazy. I ordered a new brake switch btw, so maybe that'll help.

Hey guys

I have removed all old wires, and connected new wires. Looks good and works well except for the taillights/turn signal. As usual!

The turn signal flashes way to slowly and the indicator lamps on the turn signal switch do not work. I ordered a new heavy duty flasher, but you guys think thats the problem? All wiring is correctly and all wires are good. Al contacts are good too.

well providing you haven't got the leads switched at the lights so your weaker element which normally is the parking light versus the brighter one which should be your signal element is the one doing the flashing- you may already have a heavy duty flasher.if I understand it right you only need a heavy duty if you are using extra lights from a trailer or add on lights somewhere that pull extra load. otherwise the current going through the flasher may not be enough to make it function fast when you are just using the regular pickup lights.

For some reason the turnsignal lights flash right now. but the indicator lamps still do not work. I checked all the wires and contacts and it really is how it's supposed to work.

The turn signal switch is brand new. But it might be a bad one? I dunno, i'll wait for my flashers to arrive and leave an update here...

Is the switch grounded?
For the pilot light to work the switch housing need to be Grounded to the column

DADS50, i put it on the same place as the old one, thought it would be enough! Going out to the garage immediately and ground it more properly.

If that is the issue, then i'll go to my room and be ashamed of being so stupid!

No shame with that. Easy to fix and easy to not think of.

Well that was the problem! Sanded it a lot better so now it has ground and the indicator lamps work! I feel like an idiot!

Thanks for helping!

Now I only need to get my buddy to help me with timing on the ignition and I'll be able to take her for a spin!

Also, when the i turn on ignition, switch on the turn signal it starts flashing at a good rate, but then it slowly decreases slightly, Not so much, and it still works fine but i wonder if thats normal or not?

Happy easter!

Keep an eye on the battery. If it takes a charge and works then don't worry. You might have a battery that holds a bit high voltage until it is under a load. Then it drops to 6 or 12 volts depending on what you have and gets stable. That is just fine.

Allright thanks! darn im happy! This is just great! Thanks a lot guys!
