Ha, no. Mine was a weird series of events. My batt light came on at the track one afternoon, obviously suggesting a charging issue. No obvious issue, light then went off, drove the car home, dead the next day. Bought a new battery put it in, started, showed good voltage no worries. Dead battery next day. The battery failed for some reason, it just died. So, yet another battery, car started, voltage very low... so alt test time. Discovered it was the voltage regulator and swapped it with a Bosch unit. Good to go.
