One sound I'm getting used to is the Ding-Ding sound I hear when there is an issue with my truck. It makes that noise when my fuel gauge drops below 1/4 tank. It makes that noise when my check engine light comes on. Fortunately I have a code reader and I can check and reset the check engine light at will. It's always the same code now, the power steering sensor. I'm not concerned.
Last week I heard the sound again and my break light came on this time. It appears I was low on break fluid. That was a first and easily remedied.
I was driving through town the other day and the familiar Ding-Ding alarm sounded, but this time a new light was lit up. It said "Check Gauges." The oil pressure was good. The speed, temp and tach were fine. My volt meter was dead flat. I thought the alternator or the battery was shot, but I drove on to a convenient spot to park where I could easily picked up by a tow truck. I turned off the engine and turned it back on and everything was fine and has been ever since, but now I'm driving with one eye on the voltage. I find that things that happen once usually happen again. It's just a matter of when.
