I understand the misbehavior of the DVM. That is where I am confused. I
thought the EMI filter would prevent the impulses from the ignition coil
from "backing up" into the mains supply on the other side of the reverse
wired EMI filter.
The filter will TRY.
There are limits to how much reduction is possible, as 'some' EMI/RFI
will simply radiate 'around' the filter, arriving at the input to the
DVM and...
best
