My series is having trouble starting it either starts or makes a "clunk" noise when turning the key then turns slowly to the point where repeated attempts kill the battery , I fitted a new starter motor about 2 years ago and no problems up until now. I turn they key , there is some sort of engaging "clunk" noise , when it does start it over runs by about a second , should I replace solenoid before inspecting Motor , also I've noticed that only one of the spades on back of solenoid is used , is that usual ? , Thanks in advance
