Now is the time of the year that we put a heavy load on our batteries and charging system. Shorter day light hours, running heater and or defroster, mirror heaters, and cold starts will draw down batteries if the charging system is not performing its best. Monitor your voltage gauge, remember it shows condition or charge of your batteries. It is normal to be down around 10 – 11 volts after starting and with lights and heater on, however you should see it come back up to 12 – 13 volts after a short period of time. If your volt meter is not maintaining 12 ½ – 13 ½ volts, write it up for the shop to check it out.
