[me and my metro]

I run my 6.5 GM Diesel glow plugs 1.5 times when it is below freezing with good results. The controller continues to cycle the glow plugs for the next minute or so to aid startup. My glow plugs draw 200 amps at 12 volts. So everything needs to work as designed to get this thing started. I have not added a button to this truck. The 6.5 is an indirect injected engine with glow plugs. I may add an intake heater to the mix like the early Power-stroke Fords did. This last January during a record ice storm it sat in the parking lot at work for a week without starting. Luckily I had a gasoline powered company truck to drive. I commute in a Saturn L normally and only drive my GMC Diesel 4x4 when the roads are not passible with a normal car.
