Dead or no spark until you let off of the key switch:
1. Clean ALL engine ground wires from the battery thru the engine cowling, splash pan, top cowl and support brackets.
2. Verify that there is at least 9-1/2 volts on the White wire going to the switch box (from the engine harness) while
cranking the engine.
3. Verify that there is at least 9 volts on the Brown wire going to the trigger while cranking the engine. If the voltage is
low and the voltage on the White wire from the harness is above 9-1/2 volts, disconnect the wires from the switchbox,
then check the resistance from the White terminal beside the Red terminal (from the White/Red wire on the CDI
Electronics switchbox) to the Brown terminal going to the trigger. You should read 60-76 ohms. A high reading
indicates a possible bad switchbox.
4. Check resistance between the White wire and engine ground. It should read less than 1 ohm. If it reads higher, make
sure the Black ground wire is connected to engine ground.
5. Connect a secondary ground wire (12 gauge) from the negative battery cable to the base (or case) of the switch box.
Has the smallmouth bite turned on as I get tired of catching spots everytime I come up there??
