Alternator part number
A bump on an old thread. I have a 2005 Elise and may need a new alternator. Do people think the Denso 210-0394 is the ticket? That's what MWR advertises as a replacement.
Mine has a Denso 210-0592. Has worked fine for most of the 10,000 miles of my ownership. But lately, the battery light flashes when accelerating, although battery is always charged. and belt is fine. Went to check the wires on the harness with the three little wires. They look fine but I noticed there was no bolt in the bracket on the top, and no place in the alternator to screw that missing bolt into. See photo below. So I guess some wing nut used whatever alternator was handy. Perhaps the lack of the third support bolt has contributed to what looks to be an issue with the regulator (internal regulator, yes?).
