My father once told me that in the 70's he had spotlights on his 510(to be precise, it was a 1600SSS). He and my mother drove one night with them on for the whole night.Think they were lucky not having traffic from the front.This was on a long trip on the old dusty white sand roads we had in the 70's.Think he told me they were going to visit my mother's parents.Apparently they were rally spot lights.Anyway, when stopping to get some fuel, the car did'nt want to start.
Spotlights was so strong, they pulled dead the battery and pulled so much power from the altenator that it did'nt have enough juice to charge the battery.
From there on, when he knew he was going to stop and switch off the car somewhere he switched off the spotlights to give the altenator a bit of a gap to charge the battery aswell.
