Need some help on this one please.
Drove the 92 F-450, 7.3 across town this afternoon [about 10 miles in rush hour traffic so I know it was up to temperature..] Pulled into the drive and noticed the amp gage was reading low and pulsing like it does when glow plugs cycle.
Turned key off, engine off, immediately tried a restart, and the glow plugs cycled, engine temp was setting in the normal position.. about 4 needle widths above cold. That's where it always runs.
Question: Why are the glow plugs cycling while engine is up to temperature and running.. ?
Something isn't right.. what?![dunno :dunno :dunno](/styles/default/xenforo/smilies/shrug.gif)
