Crank no start

Well that is why I'm trying to get you to completely isolate the thing from the harness and then jumper power to it separately. You may have a problem EG in the brown bypass circuit. This is a separate contact in the ign switch, and only has one job.....to feed "hot" battery power to the ign during start. It works the same way as the "start" contacts in the switch but it's a separate set of contacts to prevent feedback into the starter relay. The functional path is .........power to ignition switch..........brown IGN2 "in start"......out the switch.......through the switch harness connector........out the bulkhead connector..........and to the coil + side of the ballast. So there's several places for drop............First is the battery up? What is battery read during cranking? The drop can be BEFORE the ign switch IE the ammeter circuit supplying the ign switch, and it can be ANY of the terminals I mentioned.......along with the switch contacts themselves AS WELL AS "additive" IE a little in each one.
