Where does this go?

[twinturbo]

as dave, you should only see an output on the blue/black during cranking..

Your results is odd.

Ok, hopefully what dave suggested will be the case and I can fix it tonight and try starting it up

[brainbug007]

Ok so I checked the starter connections and as dave thought the red/black thin wire was on the wrong bolt (one on the top nearest to the block) so I swaped it onto the bottom one. I then re-checked the readings on the multimeter and they're the same as before, I'm still getting a 12v reading off the blue/black in all positions Out of curiosity I did connect the loom up to the battery negative and try checking the dash again and I do get one light coming on now (oil pressure I think?), the fuel gauge drops to zero (was previously showing full), and the water temp gauge goes up slightly by 5mm or so. Any idea's what I can try next to work out what's wrong?

disconnect the solenoid wire (the thin one from the starter) and let us know the results again at the ignition switch.

Ok tried that this morning before heading off to work and as suspected I guess with the thin (black/red) wire disconnected from the starter I now get a reading of 0 volts on the blue/black wire on the ignition. So what to do next?

[twinturbo]

Ok, that's sort of progress. It looks like you were getting back feed from the starter motor. We need to confirm the connections on the starter motor.

Do you now get any reading on the blue/black wire whilst the key is in crank?

What are the voltages on the other wires now in each possition.

The next step if you showing 0v is to do a continuity test between the ignition switch +ve terminal and the lead at the battery.

Here's a picture of the CVH Starter ( Original Ford unit )



The large teminal ( Red Arrow ) Should go straight to the Positive terminal of the battery ( 12v + )

The smaller terminal ( Black Arrow ) Should go to to the ignition switch ( 12v +, switched live )
Black/Blue wire.

Nothing goes to the Third terminal, other than the motors winding live feed wire from the solenoid ( Pictured )

The starter will get it's earth from a earth wire from the battery to one of the starters mounting bolts or other nearby location on the engine block.

I know it won't help with the strange reading that you are getting from the ignition switch but shoud hepl to confirm if the starter is wired correctly

[brainbug007]

Yup that's definately how I wired it up, thick red onto the copper colored screw (red arrow), small red & black striped wire onto the screw you marked black (I changed this after davedew's note) and this sits closest to the floor when the starter is mounted. Also as mentioned there's a really thich black wire on the same section of the loom which I have bolted onto the gearbox. When I get home tonight I'll recheck the readings with the thin red/black striped wire disconnected. Also sorry for being a bit thick/new with this but can you explain what you mean and how to do "do a continuity test between the ignition switch +ve terminal and the lead at the battery"?

[twinturbo]

Set your meter to the Ohms switch (an omega sysmbol (Bit like headphones))

Set the dial to the top left setting that looks like a triangle with a line through it. also has a representation of a sound pulse ( picture is poor )

Touch the probes together and you should get a beep whilst they are connected.

Dis-connect the plug from the ignition switch.

Touch either probe on the positive side of the battery and whilst doing that touch the probe on each of the connections on the plug you just removed.

What are the results.

Also, take a wire from the small terminal on the starter motor, and touch it against the positive terminal on the battery. This should confirm the starter is working.
