Driving truck today running fine. Engine light comes on intermittent power loss, I am able to drive home with no problem engine light stays on. Once home upon further investigation; running lights very dim, heater fan does not work, alternator gauge does not fluctuate at all (sits stable at +14v). Metering battery terminals voltage looks normal (+14 V with some fluctuation).
This problem came up with no forewarning.
Anybody have any idea's on this.
