Hey guys I'm having a right annoying problem with my 172 mk2 at the mo. Quite often (literally every other day) when i got to start the car i get electrics and lights on the dash but when i turn the ignition fully the car doesn't crank what so ever. I literally have to turn the ignition off and keep trying. On like the 5th attempt it finally cranks and the car starts fine. Any ideas?? It's getting pretty desperate now because it took forever to crank this morning so i was late for work. I've checked the output of the battery and that seems ok and the car had a brand new crank sensor last year
