      Then it's time to remove tank and check for voltage at ignition coils; if you got 12 volts here , but no spark, then suspect contact points/condensers or wiring connecting them
      Steps 1 thru 10 of this link should be useful

        check coil voltage, and resistance, coil leads, and caps, and finally plugs

          Got an update on the situation I hope I can fix this today or tomorow

          When the bike is off I have 12.5 volts

          When ignition is on I have 12.16 volts

          When I mesure the voltage to the coils from the O/W wires from the coil and the neg of the battery I have 0.01 volt

          Fuse gets very hot but passes the current , around 11.6 volts

          I cheked the wires and I have a real mess from the previous owner in the front section of the bike , But I am not sure it's the problem, because currents passes and it's around 12 volts and when I push the start button the bike cranks

          The wires in question are the one from the commands here is the pictures , they all eaten up and soldered in bizzar manner






          pictures are from my phone

            Disconnect O/W wire connector from coils and measure voltage from there to battery negative.

            Fuse should not get "very hot"- best to check primary coil resistance (disconnected), should be 3 to 5 ohms.

              Um, yeah those wires are not in the best of condition and definite rewire/repair is in order. Probably need a color wiring chart and start tracing the wires for the coils then repair that mess and any other mess you find.

              Stuff I've done to my bike:dancing: 1100E front end with new Sonic springs, 1100E swing arm conversion with new Progressive shocks installed, 530 sprockets/chain conversion, new SS brake lines, new brake pads. New SS fasteners through out. Rebuilt carbs, new EBC clutch springs and horn installed. New paint. Motor runs strong.

                .
                .
                12.5V ah, Ok
                12.16V ah, okay

                0.01 on O/W of coil to batt-
                Not Okay.

                Ignition Fuse powers the Kill switch.
                Then from Kill switch the Org/Wht wire goes to the starter button (which you say works) AND to the coils.
                If the starter button works, but you have no power at coils, then are loosing it somewhere between the kill switch and the coils. Follow the org/wht wire from right control unit, into headlight and/or under tank, look for conenctors with org/wht wires. Follow the org/wht wire from right control unit all the way to coils.

                FUse getting hot is not good.
                A 77, glass fuses right?
                See if clips corroded.
                Might be problem internal to fuse block.
