Electrical "surging"
Today I started my truck and as it sat and idled, I noticed the heater fan, (which was on high) would occasionally speed up considerably- with a corresponding jump from a steady 12 volts or so on the ammeter to a "jumpy" 14-15 volts. Then by itself it would slow down again. I was just wondering if these surges might indicate a faulty alternator or voltage regulator. thanks!
