Narrative

I DEPARTED ARPT 62C TO RETURN TO MY HOME BASE; ENW. THIS IS ONLY A 17 NM FLT. I WAS AT 62C TO HAVE NEW MAIN GEAR TIRES AND NEW BRAKE PADS INSTALLED ON MY ACFT. WHEN I DEPARTED; THE CEILING WAS 3000 FT; VISIBILITY WAS 1 MI IN SNOW. I FILED AN IFR FLT PLAN; RECEIVED MY CLRNC BY TELEPHONE; AND DEPARTED. DURING MY CLB; MILWAUKEE APCH INFORMED ME MY TRANSPONDER WAS NOT Squawking THE CORRECT CODE AND REQUESTED I RESET IT. I COMPLIED BUT IT STILL DIDN'T WORK CORRECTLY SO I CYCLED IT AGAIN. WHILE I WAS STRUGGLING WITH THE TRANSPONDER I EXCEEDED MY ASSIGNED ALT (3000 FT) BY 500 FT. WHEN I ARRIVED AT KENOSHA; AND WHILE BEING VECTORED TO THE 6L ILS FINAL APCH COURSE; MY GS WAS NOT ACTIVE. I ELECTED TO MAKE IT A LOC ONLY APCH. AS I APCHED THE OM THE LOC BECAME INTERMITTENT AND I ELECTED TO MISS THE APCH. MILWAUKEE APCH ADVISED ME I WAS OFF THE FINAL APCH COURSE. DURING THE CLB AND TURN TO ASSIGNED VECTOR; MILWAUKEE APCH ASKED MY INTENTIONS. I RESPONDED BY REQUESTING THE VOR 14 APCH. WHILE CLBING; I CHANGED MY APCH PLATE TO THE VOR 14 APCH AND CONTACTED UNICOM AT KENOSHA TO DETERMINE IF THEY WERE AWARE OF A PROBLEM WITH THE ILS (THE IDENTIFIER CODE WAS CLRLY AUDIBLE). NOW; HURRIED AND WELL BEHIND THE ACFT; I EXCEEDED MY ASSIGNED ALT (2400 FT) A SECOND TIME IN THIS SHORT BUT FRUSTRATING FLT. AFTER GETTING THE ALT UNDER CTL AND REGAINING MY COMPOSURE; I DISCOVERED THE REASON FOR THE MISSING GS AND THE ERRATIC LOC -- THE BACK COURSE SWITCH WAS INADVERTENTLY TURNED ON. I INFORMED APCH OF MY DISCOVERY AND REQUESTED THE ILS AGAIN BECAUSE IT IS THE SAFEST APCH AT KENOSHA. THIS TIME THE APCH WENT WITHOUT A PROBLEM. I AM A NEW INST PLT AND REALIZE FROM THIS EXPERIENCE I NEED MORE DUAL INSTRUCTION; CONCENTRATING ON PROBLEM MGMNT.
