My glow plugs, batterie, and connectors are 1 year old. I have trouble starting my car when it is -20 and below. When my block heater is plug no problem it works and starts fine. But my problem is where i live i cant plug it. So i though of a solution. I thought of taking an extention cord to the block heater leave it inside the car pluged in a timer and to a motormaster eliminator. Now my question is how many amps does the block heater need to run.. If my car is pluged for about 2 hours it will start.Does anyone think this can work? thanks. Forgot to say my car is a 92 golf diesel with 270 000KM.
