can anybody tell me how much amp draw all 8 glow plugs working correctly have? and where the best place to check the draw is. ?
Check amp draw when the engine is cold, using an inductive ammeter. Each bank should pull over 80 amps initially, then slowly taper down as they heat up.
If it is lower than this, you need to check each plug individually. Each glow plug should have an initial current draw of at least 20 amps. Any initial reading lower than 20 amps indicates a problem with the glow plug.
