It is highly recommended to check the glow plugs before installing a new control box. Defective glow plugs may damage the control box. The glow plug system will draw approximately 100 amps. The vehicle batteries must be in good condition for the preheat and start system to function. If the batteries cannot crank the engine they won’t operate the glow plugs.
Only the 60 amp alternators can power directly through the control box. Basic and A1 vehicles upgraded to 100. 200. and 400 amp alternators must have the alternator wiring harness modification in place (done when the alternator is installed) so the alternators output does not go through the control box. Vehicles factory equipped with 100. 200. and 400 amp alternators have the battery direct wiring factory installed.
