I got the ignition switch from partzilla.com. I am getting between 9.5 & 8.5vlts but it doesnt go below 8.5volts or it doesnt go above 9.5vlts on the pink wire i guess that voltage is ok anything lower or higher i guess the diode is fried. When i first rebuilt the bike it ran for 15mins good so i stopped the bike & went for more gas when i came back & filled the gas tank & tried to start it but no fuel pump prime unless i put direct 12vlts to it.

I switched them around & got spark on # 3 coil but only for a short time but still no spark on # 4 so i will check the power wires that are going to #3 & #4 coils & see if they have any breakage in the wires & repost with my findings
