Since we've had this '93 E150 5.8 the voltage displayed in the gauge cluster shows low. This is a picture from this weekend after about a half hour driving with AC on full -



Turning off AC, compressor and fan, moves the indicator about an needle's width. When the van is first started it'll indicate to R or M then over the course of the trip drop to O then N. So far it hasn't gone beyond N. It cranks with enthusiasm hot or cold. The headlights don't dim much at idle or get significantly brighter with revs.

I've yet to take a proper volt meter to it (I know, I know...). All but the last couple thousand miles were racked up in Boise and SLC so there might be a bad ground somewhere.

Thanks,
