Technical 55 ford not starting

Went to start 55 with 272 y block , turn key nothing ,put in new battery , new ground wire , new selinoid , voltage reg , new orig ignition switch and key cylinder , when you turn key gets power to selinoid . Car stars when hit ****on on selinoid , still 6 volt , car turns off after running when you shut the key on ignition . Does anyone have any ideas . The ign is still hanging under dash but does turn Power on do you think it needs to be mounted to dash to ground the the ignition switch although hanging it turns power on but won’t open selinoid to engage starter? Car is still 6 volt

 

Does it start if you hook a jumper wire from the battery to the small terminal on the solenoid? If not the solenoid is bad. Not the first time new parts are bad. If it does start with the jumper you have a broken wire from the key switch to the solenoid or the switch is wired wrong or bad.

 

Check to make sure the solenoid is grounded. If a 4 post solenoid, make sure the start wire is hooked to the 'S' terminal.

 

I ran a wire from selinoid to ignition to check that wire and still nothing

 

I hooked it on the ign post of the ign switch and the small terminal in th front of the selinoid

 

When I put the key in the on position and press ****on on top of selinoid it starts right up ,I have power at battery connection on selinoid and at the front post where the ign wire goes

 

I never liked that bonded style of terminal. They can get corroded under the insulation and you never know it.

 

The 6 volt selinoid I bought has the push ****on on top where the original does not , would that make a difference

 

Do u think I should change the negative power terminal to selinoid also

 

It’s a 3 post terminal

 

On selinoid

 

The solenoid is working manually, but not electrically - there's the clue. Hotwire the solenoid to see if it' will operate electrically. If it is trace back to the key to find the loss of power. The solenoids with the push ****on come in handy some times! Not seen one for years!

Starter has power wire to it and it starts up from ****on on selinoid so I think starter is ok

 

Ok I will test s terminal with someone turning key , there’s definitely power at ign and ign wire to selinoid it’s a echlin selinoid 6v but I haven’t checked if s side has power with someone turning key if not then bad selinoid right

 

Remember just because the meter or tester shows power, that doesn't mean it's enough power to spin the starter motor. Think of the flow of electrons.

 

SOLENOID!!

selinoid sounds like a bad rash

when activating the SOLENOID manually the engine starts, that’s great as it proves you have a good connection from the battery to the starter on the main power cable.

a SOLENOID is essentially a controlled short that creates an electromagnet. Positive on one side of the copper windings and negative on the other and “****” magic in a can !!!

as you’ve been told.
Make sure your on the S terminal of the SOLENOID and getting a good 12. Volt signal also check that your ground wire is properly grounded nice and clean.

one way to verify your SOLENOID is working correctly is to get a positive and negative jumper wire directly from your battery to the S terminal and ground on your SOLENOID that way you have just proved your SOLENOID is working electrically and then it’s rather simple to chase down the offending power or ground circuit going to your SOLENOID.

sorry man, good luck with this and I just couldn’t help breaking your cans just a wee bit

 

Those look like the el-cheapo "universal" cables sold in parts stores now, from you know where. They just stuff the cable end in the terminal and solder. Total junk.

 

The small terminal should have continuity to the base . If it has check to see if the base has a good ground.

 

NO. If there is no power to the "S" terminal when someone turns the key to the "START" position you have a wiring or ignition switch issue. Your SOLENOID is likely OK.

 

"Starter Relay" people, "Starter Relay".

 

good luck trying to get folks to use correct terminology....

 

Relay , solenoid , contactor , electrical latch .

also heard them called remotes , triggers and fires .

More then one way to skin a cat !

for semantics the one shown to me, is a solenoid.
Different strokes for different folks.


One thing for sure it’s not a beer !!!

 

A solenoid is a device that uses an electromagnet to cause linear motion.

A relay is a device that uses an electromagnet to actuate an internal switch.

Relays generally contain solenoids, but they have the added component of a switch. So, the thing on a Ford that switches the power that goes to the starter, is a relay. It's more than just a solenoid.

 

If you followed the info in post #2 it would be working now.

 

Thank you all will try everything tonight hopefully will be something stupid like just a bad selinoid , will report back after I try

 

Is it possible that your "solenoid" starter relay is an older type that is supposed to see a ground signal to engage the starter (like on a car with a push ****on on the dash to start) rather than a hot signal from the switch?

The father of a friend of mine used to call the solenoid, a starter switch, which I suppose would be correct also.

 

I ran into this with my OT 928 a while back, and found out it was a common problem, the "yellow wire". The wire from the switch to the starter solenoid (yellow insulation) would degrade over time until even though it would show 12V when triggered, it wouldn't power the fussy 928 solenoid- sometimes... Brought it home on a rollback one day, and the *&^$ started right up when I got it home and tried it lol...Found lots of info about replacing the wire through the harness, but tried something else first. Hooked up a standard 12V Ford solenoid to the yellow wire, and it would throw the solenoid every time. I hung the Ford solenoid from the shock tower brace with yellow to S, and 12V on one power post and the other to the 928 starter solenoid- works perfect, and with a little cable armor over the wires, looks like it came that way
