If I can't find the where the wire goes to the switch - "CAN" I make a switch like a starter switch (a push hold and release button) to use seperate from the switch? it does turn it over good and eventually starts ..but the glow plugs aren't getting "juice" .. any danger of ruining something if I by pass the switch with a glow plug switch for heating glow plugs direct from battery for 10 to 20 seconds and then turn it over to start .. ? thanks much .. gar
