I'm chasing a elctrical issue too. I too have checked with a couple of mechanics with the ski area and the head mechanic for 30 years at the county (runs all the buses for seattle) they all sent me to brad at napa in north bend wa 425 8881112. He is chasing a demond with me as well. He has made some amazing fixes.
My issue is that although I get constant 9-12 amps at the coil, my coil wire doesn't always send power to the distributor. I know about cap, roters, pic ups ect. but call brad.
