If you get sparks and rpm for a short while and then it stops sparking and rpm
goes to zero, the good news is that all LV wiring is most probably

right.
The reason the EDIS shuts down can be that the HT circuit is a bit off. Each plug wire and plug
should have a resistance of > 5000 ohms. If not , the EDIS self diagnostics is establishing
that there is an engine fault and shuts down.
I have checked this on both EDIS8 and EDIS6 modules in bench testing .
The EDIS 6 even has a pin, #4, on which you can scope the coil charging current!
Get hold of resistor plugs and/or resistor HT leads, make sure that each pair is >5 kOhms and then
I guess your troubles will be over.
BTW, I would be happy if you would sell me the faulty EDIS module( the one that got warm)
I live in Sweden. Is this possible?
