i recently installed the reverse override on my 99 sportsman 500. i did everything correct( i went back 3 times and checked) and now it isn't doing right. The override is fine, it will go full throttle correctly in reverse with no sputtering, but now the reverse light is on during High/Low/reverse. It will NOT be in 4x4 in reverse either, but will in H/L. NO engine problems or noises, just no 4x4 in reverse, and reverse light is on in everything but neutral. WHat do i do???
