Another "what is this wire for?" thread...

[BronCowie]

... that should be short-lived once Viper chimes in. ;D

It's the yellow wire off of the voltage regulator connector that has a factory connector on it and nothing is plugged into it. In the Chilton schematic it is 152A and is shown as a wire with a connector on it that has nothing connected to it. This has been bugging me for 19 years... I need to know. Shine the light please. What is this for? ?:?

I'll bet even half cab Gene don't even know dat. ;D

Well i have no idea what it does but here is a pic of what looks like that plug on mine going to what looks like a condenser ? I'm really not sure but its been there for 23 years and i have never messed with it. I would like to know what it does to also.

 

[LOVNBRONCOS]

sorry heres the pic

 

[Monster Mike]

Any idea if it has a voltage reading while the key is in the run position? Is the reading different while the motor is running?

I'm thinking it might be a factory electric choke hook up

 

[gr8scott]

Its a noise suppressor for the radio...

 

[LOVNBRONCOS]

I just looked it up in my Haynes manual and it shows it hooked up like my pic and calls it a RFI capacitor. It also show one of the other wires going to the elect choke ?

Bingo, the condenser prevents feedback to the AM radio. No other function.

 

[LOVNBRONCOS]

Now I need a radio

The electric choke would be a brown wire coming off the alternator. That way it only heats up if the engine is running, not just if the ignition is on.

That's it.

Bingo....I liked that...am radio sound like an electric forklift running in the cab wit cha...Hay my Full Cab is only half full you know....;D

I know one thing though,I have seen voltage regulators mounted all over the place under the eb hood and I know mine isn't where ford ment for it to be....Just thought I'd throw that in there....

 

[BronCowie]

Thanks all. No radio in this ride, no plans for one so it will remain unused.

Any idea if it has a voltage reading while the key is in the run position?

It has voltage all the time. Virtually a direct connection to the battery.

Is the reading different while the motor is running?

Usually, yes. The reading will depend on how your charging system is doing, and how much (if any) detectable resistance is in the wires.
It's a very short run from there to the battery though, so any loss between the battery and that connector is bad news for the condition of the harness.

You got that right! There were at least four locations from the factory on our EB's.
Been meaning to take pictures as references, but it's not important enough for me to remember when I see one I guess.

From Ford, at least in later years, that STA wire to the choke was White w/black stripe. But I've seen Brown ones too, so either they used to use a Brown one, PO's have installed their own, or the heat has just turned the old White wire to an ugly Brown.
Whatever color though, that does not go to an EB regulator at all. As Quick n Dirty said, it's from the alternator.
And it would only have been in later years. Maybe '73 and later, or thereabouts?

Same here Mark.....I am soooo sick of the radio racket...all genre I do wish I had never took the ole AM one out...lost it yrs ago...

Yep, I hear ya Gene. I prefer listening to my gal purring anyway. Plus I have no hard top, so security is an issue. I am bare bones inside, nothing any a-hole would want to break in for.
