2001 merc has a misfire between 3600-4200 and 4800-5200 RPM. Runs great from 4200-4800. I am running through the repair manual tests and could use some help interpreting the results.
does it matter if the trigger resistance is higher than the coil secondary impedence (1&4 were like this)? 2,3, & 4 have the same trigger input resistance, 1 was higher. 4 had a lower coil secondary impedence reading. stator output and stop circuit tests were normal. Trigger output 2,3, &4 were the same, 1 was higher (.3, .3, .3, .5)
does any of this mean much? Is there anything else I should check?
My resistance readings numbers were all higher than they are supposed to be but I think that is from the meter, that's why I was looking more to how they compared to each other.
Thanks for the help
