I've got a fairly new (2010) Cummins with electronic engine read-out. Been running fine the past several weeks, about 5-7 hrs/day. Today the oil pressure reading started jumping around by 3-5 psi, the alternator voltage reading kept moving from 13.8 to 13.9 and back and the tachometer reading kept fluctuating by 10 rpm. The engine was running fine. If this were an older engine, I would think the instrument voltage regulator was going bad, but with the electronic read-out panel, I would be surprised if such a rudimentary thing would be included in the circuitry.
Any ideas?
