Was the PO the OP?

Sorry about that,  I suffer from CBTJT (compulsive bad taste joke telling) it's a side effect of one of my other medical conditions, I suffer from a deficiency of caffeine.

Ford wiring

I know that I said Iím concerned about the resistance on the Ford unit, but I want to run the motor to check everything. Replacement coil prices were stupid, but I found second hand coils on eBay for GBP30 (works out to about R550.00 which is a quarter of the prices Iíve been getting

So..... the Ford coils work but I wonít be running on them until I have more info about the lower resistance.
Now I can start stripping and make pretty

I'd be careful about using coils with a lower primary resistance.  This will cause more current to be drawn through the ICU drivers, and possibly destroy the ICU (as the drivers will overheat).  Inductance mismatch between the OEM coils and the Focus coils is another concern.

👍👍👍 this was only to test the motor. Replacement orange top coils have been sourced in the UK at a decent price

Interesting.

Thanks for taking the risk. Was it hard to press the start button? I guess there was at least a little anxiety there.

I'm considering an experiment at the moment too,  but a bit worried about going to the stage of pressing the start button for fear of damaging the computers. Maybe I should do as you have, just for a short number of seconds.

It was scary to say the least..... to top it off, I had the coil wires crossed over and had to change them 3 times before I found the right pattern. 😳
Iíve let her idle for about 4 minutes to get warmed up.... next job is to undo the POís manual fan switch and figure out why he did that....

Fairly common to do around here as the cooling system is at its limit and some folks want to turn the fan on to cool the motor before the temp. switch turns it on.

Consider leaving it on,  I actually want to put one on my brick cause the fan hardly ever comes on. It could fail from lack of use,  maybe that's why the PO put it on.

I will rewire it that it works on the temperature relay and have an ďon/offĒ switch for manual operation
