Abstract
The invention relates to a method for measuring the electrical resistance of a glow plug, wherein a test current is set by closed-loop control to a constant value using a constant-current source, and is directed through the plug. A value of the electrical resistance of the glow plug is determined by evaluating a feedback signal of the constant-current source.
