Do you want me to send you my old one Cliff?Re: Cyl 1 & 4 = no spark
Thank you for the information on the switching transistors. I've always assumed there were switching transistors for the coil operation but did not know if they were serviceable.
Anyone have an old or toasted ECU they'd volunteer to send me? I'd like to see if it would be possible for forum members to repair that section using better rated transistors.
That does seem to be the common failure.
I sourced a second hand EU unit.
My regulator rectifier was also replaced along with a coil.
So to cut a long story short the ECU was broken.
