2004 HONDA GL1800A Engine Problems

I HAVE A 2004 HONDA GOLDWING WITH A CALIFORNIA SIDE CAR KIT. I PURCHASED IT FROM THE SECOND OWNER ABOUT 1.5 YRS AGO. ABOUT A YEAR AGO I WAS RIDING A BACK ROAD WHEN THE STARTER ENGAGED. I HADN'T TOUCHED THE START SWITCH? I TRIED THE KILL SWITCH BOTH POSITIONS AS THIS MODEL HAS AN UP AND DOWN FEATURE. I THEN TURNED THE IGNITION OFF, NO AVAIL. FINALLY IT STOPPED ON IT'S OWN. AFTER RETURNING HOME IT WOULD NOT RESTART, I DID A CHECK AND FOUND THE START RELAY WAS FRIED. A FEW WEEKS LATER IT HAPPENED AGAIN SAME SYMPTOMS AND RESPONSE TO WHAT SHOULD HAVE SHUT A BIKE DOWN SAME RESULTS. I HAD IT TOWED TO THE DEALER IN LAKE CITY, FL. AFTER TRYING TO SELL ME A NEW BIKE PIECE BY PIECE I PAID MY $1K AND LEFT WITH A NEW STARTER AND NEW STARTER RELAY. A COUPLE...
