When starting a cold engine, glow plug cycle time can last 18 seconds with an after glow time of 30 seconds depending on engine temperature. Average glow plug amperage draw is 130 amps. The intake air heater may draw as high as 45 amps. Due to these high current draws the battery indicator may remain on until the amperage draw is reduced.
