Had an 1100ET when they first came out . Had charging problems , burnt out the reg/rec . Checked out wiring harness , positive (RED) cable from battery goes under battery box and is made into a soldered Y joint . Found this soldered joint broken on mine ,making intermittent contact . Repaired joint with solid connector , all good . Great power , bit of a head shaker so fitted fork brace [which I still have ] .
