91 audi 100. may be more like a 5000 platform. not sure. when damp/wet/rainy and headlights on voltage drops from 14V down to 10v. a few times, the battery light came on and sometimes it stalled. does not do it all the time. very sporadic. sometimes it does it with the heater on only.. any suggestions ???
