My 1998 ST2 has just started exhibiting some strange symptoms when starting up (hot or cold). When I press the start button sometimes the starter motor tries to start turning the engine over but can't - it seems to turn the engine very slightly then sticks. If I try again a few times it will usually get it started on the 3rd attempt but in the past it has always fired up on the first press. Also sometimes I press and release the starter button and the engine does not fire up but the starter keeps turning over even if I turn off the engine run switch and turn off the key. The only way to stop this is to turn the engine back on and when it eventually fires up if I then turn off it will have stopped cranking (usually). Battery voltage is 12.7 with no load, 12.4 with engine and headlights on but engine not running, with the engine running it's at 13.5 at tickover and drops to 13.2 if I rev it. the battery seems to hold charge OK over several days if nothing is switched on. When starting, the voltage drops to about 5-6v if the starter sticks and about 8 if it's cranking over. My thoughts are maybe the solenoid because I can't see how else the starter would keep cranking with everything switched off but that wouldn't explain why it can't turn the engine over. Also not sure about the battery voltage when revving it up, is 13.2 about right? Any ideas/thoughts please? Ta Jim
