Ignition relay

[twinturbo]

When you switch the ignition switch off the +12V supply on the Black and Yellow is switched off but it's not grounded.

ok, goood, thats what ive done. Now, its rturning over fully but not starting, the black/yellow is correct as when i put it on, theres 12v at pin 10 of the hybrid ignition module. ALso, in the auto trans relay did you say to short pins 86 and 87, as ive also shorted it to pin 30 on the relay to connect it to the starter solenoid?

One Caviat..

On some of the injection engines, like the 2.9. A circuit ( 50-7 on the 2.9 ) is fed from the starter circuit during crank. In that case it goes to the TFi module and alters the timing advance to make the eninge start easier.

But on the 1.8 Carbed CVH it's not present.

hmmm.. ok, i also remembered yesterday you mentionted the 4,6, and 8 pin pulgs, i have nowhere to connect the 8 pin one to?

[twinturbo]

8 pin is not used on the Early 1.8CVH loom from what I can see , if you Dont have realy XI then the 8 pin will not be in use.

I would leave pin 30 Disconected on the Inhibit relay. It should be redundant with 86 & 87 Joined.

TT[/QUOT ,
If i left pin 30 disconnected, what does the blue/black wire form the ignition switch go, as ive connected pin 30 to the blue/black wire? i think thats wrong now that you explain it to me.

Also REALLY THANKS FOR THE HELP!!!!!

Ok, Ford in their wisdom have 2 verisons of the diagram

Diag 3A for "Automatic Cars"
Diag 3B for "2.0 DOHC Cars"

No Diag for non Auto cars or non DOHC cars is specified....

I plumped for the latter


Sounds like the CVH must conform to 3A instead, in which case

Circuit 50- from the switch (SW-BL ) does indeed go to Relay XII pin 30. And in non auto form would be Jumpered to pin 87 also (SW-BL).

Forget the other two pins

hmm, that makes me think how the xii relay was turned on, as i cant seem to get it to. oh well, ill keep trying
