If this started happening after the start motor was replaced, then focus on the connections that had to be removed to do this work. I've recently been in there myself and the LCI car (M5TU) routes the alternator output via the main starter terminal, so there's lots of scope for connection problems here. The two large cables on the main terminal of the starter motor seem to need to be connected the correct way around. The line from the alternator goes UNDER the line from the battery/jump start terminal.
