Light issue

I replaced the turn signal switch on my 84 250. Now I have no flashers, when the flashers get turned on it lights up on either side and stays bright. Any idea what’s going on? I’m at my wits end. All the fuses test good. Just put a new flasher fuse on it. Help!

I have put all new LEDs in it. If that makes enough of a difference?

change the Flasher to a Solid state flasher, or put resistors in the lamp circuits.
The LED bulbs don't draw enough current to make the flasher work.

Got it. Thank you lone wolf. You’ve been a huge help with everything. Thank you so so much.

I’m picking up a flasher today after work. I’ll update later.

here is a link that might help in your choice of Flasher https://www.hotrod.com/articles/ligh...-flasher-leds/


Most folks that I have seen like the LED flasher with the separate Ground wire, I still use conventional so I cannot say which is the best.

Lone wolf,

is there a separate flasher relay for front and rear or should it all be on the same relay? It still isn’t working.

there is 2 Flashers on the 84 one for turn signals and one for Hazards. the one on the fuse box is for the turn signals.
as per the web link is the X and L orientation the correct polarity ?

what Flasher did you get ?

We just got wrapped up for the night.

We put the old incandescent bulbs back in the brake lights, and lo and behold, it all works properly now.

It didn’t even work with the LED flasher in it. Not sure why. Must need resistors on the leads up to the brake light. The front turn indicators are LED and they work fine too.

ah well. I’ve still got LED back ups so I can see what I’m doing backing up. Life will go on. Or back, as it were.

Tried both of these. Neither one worked. Even ran jumpers for the second one. Put the original one back in and all works well.

what I do know that works is the LED flasher with the separate Ground wire... BUT if it still don't work you're side markers are likely common grounded through the front signals' park & flash feeds.and you will have to move the marker Grounds.

if the flasher sits too tall it can be re located but the Hazards will not Flash unless you change that one too.

you could possibly use some resistors on the rear and solve the problem too... it always seems to be a PIA to get our old Fords converted to LED... there doesn't seem to be just 1 simple fix.
and IF I remember correct even the flasher with the extra Ground wire requires the Polarity Adapter that normally comes with them.

EDIT: I need to rethink this post see POST #13 at least the part on what type Flashers will work.
EDIT #2: Yes the 2 prong with the extra ground wire will work... I have edited post #13 to be more correct there is an error in the Manufacture's schematic.

Personally I don't like to fix things that ain't Broke
But welcome to LED Hell, you are for sure not the first.

The hazard flasher is located on the firewall side of the fuse box. The turn signal flasher is on the fuse box side facing the driver. Did you change both of them?

it's not an issue with the Hazard Flasher... and you don't need to change that Flasher unless you want the Hazards to work... there is no requirement in Texas that Hazards must work for a State inspection.
That may be different in other states, BUT the primary concern is to get the turn signals working right first before worrying about hazards IMHO

here is a Schematic of the 2 wire Solid State Flashers that use the external Ground ... some even have a Trimmer Pot to set the Flash rate,EDIT they do not use current or voltage feedback to function.when power is applied to the Battery and Ground Terminal the Relay starts to cycle at the Determined rate.) <<==== this is not quite correct, I would be correct IF the Schematic shown in the image was Correct, in general the schematic is mostly right but they left out the Feedback lines. This Flasher does in fact detect LOAD before it energizes and starts to cycle.




While the unit shown has 3 pins it is the same as the type with 2 pins and a Wire.


EDIT: the Issue I see is Based on the Above schematic being complete and correct which it is not.

I do see a possible issue with this setup as the TS Switch switches the load and the Flasher has Power as soon as the IGN key is turned to RUN so I would think this style Flasher in the 84 application might be a Flawed Idea.... I would think with this style that the brake lights would flash constantly ... Hmmmmm unless the 2 pin flashers with the Ground wire are not as depicted in my schematic.
SOB now I might have to go out and buy one of those flashers to test it myself just to find out.
EDIT: this is the Flasher I tested https://www.ebay.com/itm/TURN-SIGNAL...2/254342883686

This is a more Correct Schematic of the Flasher including how to add a POT to change Flash Rate (Some of these Flashers already have this feature)



The Turn Signal switch is just shown for simplicity of a complete Turn Signal System Refer to other Diagrams I posted for the FORD Application.
I hope this Clears up the CornFusion a bit.... it sure does for me

Lol. Let me know what ya find out wolf. For now, I got turns, so I’m happy. I’ll double check the hazards when I get back to it.

The old girl had been sitting being barely used for a few years when I bought her. So she’s just a little cantankerous. Needed quite a bit of work to get her up to MO state inspection status. (Needs a bit more yet) Should finally have all the issues buttoned up tonight and back on the road. Finally.

OK here is a case in point... I know it don't really apply to the 84... I'll get to that later....



This I understand 100% it makes total sense
ok now this........


This I understand 100% it makes total sense
on both the above schematics the DIR FLASHER is not shown but it is a Given that it has 2 terminals one is X to power the other is L to Load in both Schematics the Dir Flasher Terminal depicted is from the Load side.....

OK now we have this......


This is the Solid State Flasher Version that makes no sense from FORD
SO I think to help you folks out I need to Test one of these Flashers to see how they actually work....
BY this Schematic it does not look like it could possibly function.
I see the Issue, it's in the switch Do you Folks see it too ?????????????????
