car wont start with the keys
there are for connections on the starter solenoid. these are:
1.) the + from the battery to the solenoid
2.) the earth from the starter motor ground to the solenoid
3.) the wire from the ignition switch ( when in cranking)
4.) the wire from the + coil.
Ok, there is an internal connection in the solenoid. This forms a closed circuit when there is current in the switch wiring( when cranking) and from the battery + side as explained above.
I have tested the current going to the solenoid from the switch and it gives a reading of 12.15 V. I have also tested the voltage from the battery[12.37V] and have found a good ground on the solenoid producing 12,37V.
The car will not start. The Solenoid is NOT faulty. I have removed the starter and the solenoid from the starter and it worked well when not connected to the starter motor.
The car will start if you bridge the + battery with the ignition switch(in cranking position). Therefore the starter

motor is fine. The car then starts. The ignition switch, battery, distributor and all wiring has been tested and works as per manuf. specs.
I dont understand why the starter motor doesnt turn when 12 V are going to the solenoid. when i bridge the wires it does.
PLEASE HELP !!!

If you have tested the solenoid and it works outside the car, if you have tested the starter and it work outside the car, if the starter and solenoid will work if you jumper to the ignition connection of the solenoid then there is only one thing that can be left...
The wire from the ignition switch or the switch itself is faulty and you are not getting enough current through the wire to engage the solenoid. Yes, you can still measure a voltage there but that does not insure that you can produce enough current.
You stated yourself that if you jumper from the battery connection to the ignition connection it will start (because you are getting enough current) and you stated that you have 12.15V at the ignition connection when the ignition is engaged (proper voltage) then it must be the wiring or switch limiting the current.

Your description is not precise & clear.
I'm not sure what you mean by 4) the + coil.
You mean voltage to the solenoid, not current.
How can a good ground on the solenoid produce 12.37V?
If bridging the + battery to cranking wire, starts, motor's good.
What this sounds like is transmission interlock.
There's a Neutral/Park switch which must be closed.

the solenoid is just a big switch,
when the wire from the ignition switch has 12 V across it, the solenoid electrically connects internally to the other wire.
if you have an external solenoid,
sounds like you solenoid is bad,
either that or the metal connection from the metal case of the solenoid is not well connected to the frame of the car (that is the return electrical connection for the power from the ignition switch).
Replace the solenoid !
if the solenoid is attached to the starter, then your description is not clear enough for me to get.

eather one of the battery sells is bad or there is a flat spot on the starter armiture.
have each cell on battery hydro tested first
Good luck
