Alternator Light in Cluster

Alternator Light in Cluster
hi guys
i am running an e420c in my NB-B 2001 model.
after i wire it all up, i am getting a battery warning light litted in my dash.
with a multimeter, i checked the charging on the battery.. and it is perfect, 13.5Vs.
does anyone have a clue why i could be getting a battery warning light in the dash?
i checked the wiring diagram and everything related to the alternator is connected.

Now, the OP didn't tell us whether he was running parallel or not, but I can't think of a reason why you would with an e420c.
On the NBs, the light in question is controlled not by the alternator itself, but by the ECU. Sadly, I do not have a complete wiring diagram for a 2001 (2000 is the latest I've got for the instrument cluster) however I think that it's the Brown/Red wire at pin 3U of the 2001 ECU. So check out that wire, see where it goes. If you've grounded it for some reason, then the light will come on.

thanks for the fast response and informative replies.
the IAT on the stock ECU is not connected as i have only connected the GM IAT to the e420c. i was only of the opinion that the missing IAT would probably trigger a CEL, which has been there for ages, so did not bother about it.
the e420c is running in parallel.. i will try out the IATs and hopefully it resolves that problem.
on a sidenote, does anyone have problems with datalogging on Wari latest software? i clicked log, but nothing happens.

it works! alternator light is gone after i wired up the resistors going into IAT back to original ECU.
thanks guys.... now only left with
P0107 barometric sensor
do the rest of the adaptronic guys with 02 miatas have the CELs on all the time?
