I have a 2005 Lotus Elise that begun winking or blinking the battery / alternator light during my last track day. The winking (it's not a constant blinking) is very sporadic and seems to come and go.
I was able to capture some of its behavior on video. The battery light is the red light on the left bottom row that stays lit up.
Before I start the engine it seems to blink as some solenoid pulses(maybe the fuel pump?). Then after I start the car the light flickers and then seems to flicker out as the engine revs.
I've also recently experienced the battery light not even coming on when the ignition is keyed, it stays dark for a few miles and then seems to come back when the car is slowed down to idle.
I have checked the battery terminal connections and have charged the battery. I also checked the fuse on R3(Position Alternator Sense) and it's still good. The serpentine belt visually looks good but I remember smelling some burnt rubber aroma from the engine compartment after my first session or two at the track.
