ok a little history 1975 (month 02) fj40 semi-transistorized system, everything working fine with point system then I got greedy (by spending $300) wanting to add some extra miles to gallon then everything went bad. Here is what was done: -removed points, ballast resistor, igniter and stock coil Replaced with: -new Mel's ignition from JT Outfitters (finding out later it is just a repackaged Pertronix, man I hate misrepresentation) -new MSD Blaster SS coil -new plugs -new cap/rotor Has been running fine now for exactly 6 days, then after coming back from the longest trip yet since changeover (approx 30miles) I was sitting idling then stopped, nothing, dead, toast. discovered on the roadside test I have no spark? du other things noticed: -cap contacts look like they had 3 years on them -the magnet sleeve had a slight film of black gunk Unknowns during changeover: -the mel's kit said it was plug & play well not quite. the magnet sleeve was to just push down over the point cam so the top is in line with the top of the cam except it did not drop down inside the breaker plate. So a little grinding to the top and bottem of the magnet sleeve and bottom of rotor then voila everything fit. -the points cover was removed 'cause igniter module sat to high -removed the lead from the starter to the coil + -old book calls for NGK BP5EZ plugs, asked partsguy to hook me up with one hotter plug sold me NGK BPR4ES -plug gap called for .039in (1.0mm) set them to 0.047in (1.2mm) Checked fuses, yelled at sister, kicked tire and still won't start. Where did I go wrong ?
