SO YOUR 1980 OR 1981 C70 PASSPORT WON'T ELECTRIC START HUH ???

----------------------------- FIRST SEE THE PICTURE TO THE LEFT TO MAKE SURE YOUR BATTERY VOLTAGE IS IN FACT GOOD ENOUGH 6.3 VOLTS OR HIGHER (A_MUST) -----------------------------

OK

SO THE ROOT PROBLEM IS (95%) A BAD GROUND TO THE STARTER SOLENOID PRIMARY COIL, YES GROUND.

THE SOLENOID PRIMARY SIDE (THE_TWO_SMALL_WIRES) HAS A FULL TIME 6 VOLT HOT WIRE GOING TO IT WHEN THE KEY SWITCH IS TURNED TO THE ON POSITION.

WHEN THE GROUND SIDE MAKES A GOOD GROUND THE SOLENOID DOES IT'S THING AND PUTS EVERY BIT OF 6V POWER THE BATTERY HAS TO THE STARTER THROUGH THE BIG RED + POSITIVE WIRE.

SO LETS TRACE THE GROUND BACK TO THE BATTERY, THERE ARE A LOT OF "WEAK_LINKS".

I AM ASSUMING YOU HAVE A GOOD FULLY CHARGED 6V (6_VOLT) BATTERY !! GET ONE IF NOT (:

MAKE SURE THE BATTERY TERMINALS ARE CLEAN AND MAKE SURE THE GROUND (-) CABLE IS MAKING GOOD GROUND TO THE FRAME, ESPECIALLY IF YOU HAD YOUR FRAME PAINTED OR EVEN MORE, POWER COATED.

YOU MAY WANT TO JUMP TO THE LAST 2 ITEMS AT THE BOTTOM OF THE PAGE FIRST AND TEST THE SOLENOID AND STARTER TO ELIMINATE THEM

OK

WORKING BACKWARDS FROM THE SOLENOID

(C70_80/81) CLICK TO SEE AREA WHERE DRUM NEEDS TO BE CLEANED FOR BETTER CONTACT

WEAK LINK #4 CHECK ALL THE SMALL WIRE CONNECTIONS -- SEE THE DIAGRAM WHERE THEY ARE AND THE COLOR

SO IF ALL 4 OF THE ABOVE WEAK LINK ISSUES ARE RESOLVED (AND_STILL_NOT_STARTING) THEN TEST THE SOLENOID --- WHEN THE START BUTTON IS PUSHED YOU SHOULD GET A CLICK NOISE AND VOLTAGE BETWEEN THE TWO STUD BOLTS SHOULD GO FROM NO VOLTAGE TO 6+ VOLTS OF DC CURRENT

SOLENOID LOOKS GOOD THEN TEST THE STARTER --- USE AN OLD SCREWDRIVER AND SHORT THE TWO SOLINOID TERMINAL DIRECTLY WITH EACH OTHER -- 100% CONNECTION -- THE STARTER SHOULD SPIN UNTILL YOU RELEASE THE SCREWDRIVER -- IF NOT THE STARTER NEEDS REBUILT
