I am having problems getting spark plugs to fire in a AQ125 Volvo Penta in a 1983 Bayliner Capri. I put in new NGK BPR6ES plugs which are supposed to be a good cross reference to the Bosch W6DC shown on the engine, but I get no spark. I can get spark when I put in Autolite 2852 spark plug that came from an old outboard Force motor that I had laying around. I checked it on all 4 cylinders , so I doubt I have 4 defective new spark plugs. I did all this with the old ignition coil in which has an external resistor. I put in a new iginition coil with an internal resistor because I was going to install an electronic ignition conversion kit. I thought replacing the coil might fix the problem, but still no spark. Before I install the conversion kit I want to make sure the plugs are sparking. Any thoughts?
Thanks,
John
