Sounds like it might be the alternator diodes playing up before they fail altogether?

Not had it happen on TR7 but on my Integra the ignition light would come on often even though voltage reading was good and never had a problem with battery. There was a vampire drain in the system at .3 amps which meant when I left the car for three or four days the battery would be flat. I had sprayed the ignition switch with graphite and it was conducting a current when the switch was off (and presumably interfering with the ignition light balance circuitry). I flushed out the graphite in the ignition switch with silicone spray and the vampire drain stopped and the ignition light didn't come on. I would spray the ignition switch with silicone working it back and forth and see if that fixes the problem. Can't hurt and is probably something that should be done anyway.
