A Solenoid Question
RE my last thread ' Advice Wanted' the quest is still ongoing for a 6 volt positive earth solenoid .
As alot of the CMP Ford electrical stuff is the same as early Ford Mercury ( I realise this is a little off topic) is the solenoid the same ( ie as above 6 volt positive earth) part number 21A-11450 as all the manuals I have don't seem to give a part number. I have finally tracked down someone in the States who has parts but has 3 or 4 variations of solenoid so I want to make sure I get the right one. Any help would be appreciated. |

In the Ford CMP parts manuals the solenoid is listed as 01A-11450 A.
Macs Antique Auto parts has them listed as 01A-11450 (Steel case solenoid with starter button). Works on 6v positive earth. 21A-11450 is listed as a Bakelite case without button, but cheaper. We get the steel case solenoids here regularly at swap meets fairly cheaply, but they're Chinese or Indian made and last a matter of months before dying. www.macsauto.com/index.html |

A question
Is it the solenoid which determines pos or neg earth?
And, on the modern 12v solenoids of the same shape there are two terminals as opposed to the one on an old CMP one (the small one which is connected to the starter button). What's the other used for, is it accessories?

Polarity
A solenoid has no polarity (Pos earth, Neg earth) but is voltage specific. The solenoids with one small terminal rely on the mounting tabs to grounded. Supply battery power to the small terminal will energise the solenoid and connect the two large terminals (On some solenoids, the contacts are normally closed amd supplying power will break the contacts). On solenoids with two small terminals, the body is insulated and the two small terminals need to be wired to battery (usually through a switch) and earth, which will then connect the two large terminals. Solenoids are available in a range of voltages (6v, 12v, 24v) and configurations (Grounded body, two terminal, contacts open or contacts closed). Solenoids with the push button like the original 01A-11450 A are becoming hard to source. All the button does is manually close the contacts, which is handy to turn the starter when you're in the engine bay doing a tune up..

The button is also useful hot wiring
The 6volt solenoids with button are very common to Ford, Lincoln, and Mercury of the forties and fifties. Though, they are designed for different voltages I’ve seen the 6 volt work well on cars converted to 12 volt. Not sure of the other way around.
My 49 Lincoln has two of them one for the starter and one for the hydraulic pump for the windows. The biggest advantage of the button is for checking a starting problem is battery really not turning over or is the ignition switch at fault. I think the button was done away with in the fifties because it was possible to start the car in gear from under the hood if the key was left on. Also, it did make the cars very easy to hot wire the car. I’ve only had one of these fail and it was on my 89 Ford Taurus the wire for the solenoid coil broke of inside the case. Started the car with a pair of pliers connecting the two side terminals with the handles, when I got home drilled out the two rivets holding the end cap on and re-soldered the lead until I could get a replacement.

Thanks all for your replies and help.
The reason I thought solenoids were positive or negative earth is because I was told this by 2 different auto electricians. Cheers Richard Hughes |

Lets be absolutely basic, a "solenoid" is a cylindrical coil of wire acting as a magnet when a current is passed through it. The term has found worldwide mis-use for a relay or contactor used to switch the high current supply to the engine starter motor. A solenoid, when having a laminated iron core to intensify and concentrate the magnetic field, is called an armature; these are found in motors and relays/contactors. Similarly mis-named worldwide is the ignition coil which is actually two coils mutually (by magnetic field paths) coupled together and is in fact a transformer. R. |

So what's an Accumulator and why don't we call them by that name any more?

The reference works suggest the usage of accumulator for a large, rechargeable electric cell is peculiarly British. Similarly you don't hear much about charabancs these days either although we seem to have plenty of busses. If you think Lucas is bad, try Miller electrics. . . . . . . . . . . . R. |

Surprisingly the illustrated (and very detailed) "Motoring Encyclopedia" of, we guess, mid 30's owing to the vehicles depicted; has one short 36 word paragraph on "Battery" that ends "See Accumulator"!! This latter section covers several pages with copious pictures. Perhaps a WWII rationalisation of terms, especially with the off-shore influences. Quote:

Accumulator
ELECTROLYTIC CAPACITORS ARE A FORM OF ELECTRIC ACCUMULATORS ARE THEY NOT?
JUST A THOUGHT |

Yes, I was thinking of a Battery, but I suppose a capacitor will also accumulate an electric charge.

I thought the term "Accumulator" had dropped from usage to avoid confusion between the old item and the owner of many such old items. Last edited by Tony Smith; 05-02-05 at 05:27. |

Accumulaters
I know this is right off the original subject, but to carry on regarding Accumulaters, they are, since the 1940's something completely different.
An accumulater is to be found in some hydraulic systems and consist of a cylinder with either a bag filled with compessed gas within it or a piston, one side being charged with gas and the other, oil from the system. They can act as a shock absorber or to store energy within the system. Maybe in Southampton it is called something else? The English language is wonderful for using the same word to mean different things Richard |

And...
...a 'motor' to a North American is an 'engine' to the rest of the world, and in the rest of the world a 'motor' is electrically-powered and usually provided by current from an accumulator aka battery! However, in railway parlance, an 'engine' is a 'locomotive', and a diesel-electric locomotive has an engine and motors! Forgive me but I have spent over a week doing nothing but editing a book on diesel-electric locomotives written by a guy whose English is worse than my 7-year old's!
Just thought, to us of a certain age, a Morris Minor had a 'starter', which meant that when the accumulator was flat so not providing power to the starter motor, the Husband was used to start the engine with a starting handle inserted into the crankshaft end...hence Husband = starter! |

This reminds be of one of my Australian visits. I was with four Australian friends, all mv enthusiasts and we were on our way to the annual show at Corowa. We stayed at a pub in a small country town, Narrandara for those that know it. No breakfast was served at the pub, so my friends went off to look for a cafe. I suggested we get the motor (a Land Rover, which had all our kit in it ) and bring along to the cafe. One of them, looked at me and dryly said "that if I wanted to pull the motor out, I could do it on my own".....from then on I had to remember not to call a vehicle a motor ! The person in question is a purveyor of Land Rovers and Blitzs and one time Cent owner, I am sure many from Vic and NSW will know who I mean and recognise his humour Richard |

Solenoid
Thanks, everyone for their assistance.
In the end, Robert Farmer (sparky by trade and CMP owner) came over to assist along with Ashley and Max and he just made it work... so well the first touch of the button it fired up!
