2003 Passenger van, 135,000 miles
Drove across Pennsylvania with the glow plug light on. A look at previous Forum posts suggested it was a misleading short, so I figured I could make it home. But that evening, the battery was a dead as a doornail. But the battery was already on its last legs (age -wise). Had the Freightliner dealer install a new glow plug module, and a new battery. Question: Were the glow plugs drawing current all day, (in which case they might be toast and needing replacement) or is it was one of those misleading coincidences?
