rx 951 millenium edition

I love this Form, just recently joined about a month ago. It's been a great help. I have a very strange situation with a 2000 Seadoo RX 951. The spark will sometimes happen and then sometimes not at all. I immediately thought it was going to be the Pulse coil. So I tested it with a Meter...

Hi anyone know the part number for the regulator? I have not been able to locate any part numbers? Also is there a way to cross reference the part numbers between skis to see if another one will fit? Thanks.
