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

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

THIS IS WHAT ONE GOOD CUSTOMER SAID ABOUT THE TRX SENDING UNIT.....

"I just rec'd the 93-95 TRX Revl neutral switchs that I ordered for my 81 C70 and after taking some measurements, i installed it in the bike and it works fine. I didn't have to do the mods that you suggested. Just thought I'd let you know. It may stop working once it wears in, because its very close."

Thanks, JOHN F.
