52 F1 solenoid
 

Hi guys

Trying to cleanup some of the trucks wiring. If you can make it out...there is a red wire going from the small terminal on the left to a ground (actually one of the solenoids mounting bolt) bolt. Is that really necessary?

Are the smaller outside studs grounds?

It would depend on the model of solenoid it is, but seems odd.

I have never seen this style before, but here it is!

Hats off to you once again!

I guess it don’t matter but according to the pic and my pic it looks like mine is upside down

Also mine is 6 volt

ANDY

Picture attached of my 52 6volt. Red wires go to voltage regulator and horn relay. Small wire to starter button. Heavy black to starter and from battery.

Hope this helps,

Tom

Hey Tom, hope all is well.

I have an odd ball setup. Jerry found answer.

Re: 52 F1 solenoid
 

How does this translate to 6 volt positive ground systems?

Re: 52 F1 solenoid
 

The instruction sheet says 12v, so would assume negative ground. Think the point is this type of solenoid exist. I have no idea if there is a 6v version, but would guess there is as Andy stated his vehicle is 6v.

Re: 52 F1 solenoid
 

When I built my engine test stand, I set it up for 12 volt negative ground and bought a appropriate solenoid from NAPA.

About 6 months later, I had a '51 Mercury engine I wanted to test. I put my Optima battery in the battery box and switched a few wires around, and tried the engine; it stared and ran great. A couple of days later, I realized that I had not changed the solenoid. Since it worked with no problem, I just shrugged my shoulders and kept on doin' what I was doin'.

That was about three years ago, and I have had several engines on the stand (both 6 and 12 volt) since, and the solenoid has never missed a beat.

What you have is a constant on solenoid you can ground either of the smaller post and by the same token you can light up either the smaller post to get the solenoid to work and what it is is not a regular starter solenoid but a solenoid that they use 4 heavy amp usage instead of burning up a switch you run the big wires through the solenoid they were great for starters and where they really shine is on things like fire and tow trucks where there is a ton of Lights and you run it off the solenoid and let your switch just energize it

solenoid grounds through the base to cowl. On a 4 pole solenoid one of the small post goes to the starter button the other is a momentary straight 6v to the coil. I haven't seen a metal version like you have. Pretty neat.


The red wire going from the mount bolt to a ground isn't really needed, but I bet it works well. Take the solenoid off and clean a little paint off the the cowl and add a washer to assure a little more surface contact. Then you can remove the wire (if your bat 2 body is solid).

Tinker, that is how most four terminal solenoids work, this is a different type that can be switched between ground triggered and power triggered. It requires the jumper to ground to work.

Re: 52 F1 solenoid
 

Noted. Sorry. Never seen this, and picked the wrong red wire.

What's the reason or benefit?

Okay I think I get it??

Re: 52 F1 solenoid
 

I have never seen this type before either, interesting setup.

Re: 52 F1 solenoid
 

Tinker, there are 5 different 4 terminal solenoids that are all wire differently internally.

Okay Bob, this helps. Thank you.


Designed for a system that has 24 or more volts to run equipment (like a firetruck) but not run the solenoid down. Or what i'm reading. maybe...


This looks to be a circuit 9. If I'm reading to correctly. Maybe 6.


Interesting.
