Hello together I came across your forum today by Google and immediately signed up. Because…..I have a problem. I drive a Sierra 2.0 GLX – type GBG – 88kw/120PS – day of first approval 07. 1991 Since Friday noon lights up when the engine is switched off and the ignition key is pulled off, the battery light in the tacho. As soon as I kick the brake pedal, the light becomes much brighter. I start the car again, the lamp goes off, everything runs perfectly and the lamp also goes the g anze ride over no more. But it seems to flow enough current in the standing state, because this morning ( Saturday ) the battery was completely empty. Now I have installed a new battery, which I have now separated from the pole, so that it is not again directly empty. Have already pulled off some plugs and connected again, but have not found a real solution yet. Does anyone know this problem and possibly have a tip for me? Greeting Michael
