Bob,
I have used many sets of the MSD 'Universal cut to size' 8.5mm wire sets. Yes, should definitely check the resistance. Every lead. These universal sets come with the spark plug end already terminated. On the last set I used, after terminating the dist cap end, it measured high resistance, not the 100 or so ohms it should. The problem was a poor termination on the spark plug terminal.
So much for Chinese QC!!
Another 'problem' with these wires [ & they do not mention this in the instructions ]: the helical wire is copper with an enamel insulating coating. If you do not want a high resistance connection, the enamel should be scraped off to reveal bare copper.
