Looks like only Resistor  type at sensible price end!

My Son-in-Law runs a firms Ford Mach-E he has had it for about 18 months or so - it does have a decent range 260 or so miles.
If you have to use a public charging point it's as expensive as a Petrol vehicle to run. Home charging with a special EV tariff seems to be the  way forwards.

The difficulty as I see it with a fully  EV is when the battery fails most all electric cars will be worthless, I do know some Merc hybrids are failing in under 10 years with replacement battery units costing close to £10k for a hybrid.

I do like the idea of the optional range extenders on the early small BMW i3 that had the abilty to charge the battery as you were driving. I ended up replacing our 19 year old Jeep G.C .3.0 CRD with a Volvo XC30 MHPV as a compromise for the cheaper VED.

I suspect there is a lot of development work still to come not just in battery construction materials but also in terms of electric motor types e.g. Axial Flux or Radial Flux plus some sort of commonality on what voltage electric motor is used.

IMHO buying an all EV is presently on a par with the original Ford Model T in terms of the development curve.

My wife has a 2023 Jazz Hybrid ..  complicated yea but does 67 mpg even around town and lovely car to drive without any nasty laggy CVT gearbox to contend with and she can go to Leeds and back each week with journeys whilst she's there, without worrying about charging. So don't think we will ever go EV. A guy at work try to tempt us into buying a Renault Zoe but even the 55kW version of that would be borderline doing that weekly journey without charging. Probably OK for you though Johnnie if you just do short local journeys.

thanks.

can you remember if the red was positive? when you switched, do you mean you put the red on the white terminal and white on the red terminal?

I've messaged who I purchased them from.

but how can I can test which terminal is which?

Yes, red and white wires are o new coil and yes they are supplied overly long.

Thanks for the tip!

FWIW my Hendler coils were wired for positive earth so I had to switch them to negative earth - this caused clearance issues  in the mounting position so I had to ensure the spade terminals did not touch the frame on the inside edge.

The Devil is in the detail when fitting aftermarket options.

My company is trying to push us towards ev’s at the moment. As I do around 200 miles a day I will point blank refuse and if it means seeking alternative employment then so be it. I’m not doing a full days work then having to stop to charge up before I can get home.
If I worked at a fixed location within a reasonable distance from home then it would be ideal.
