I have replaced the rear shocks on my 91 BMW 318is. Also fixed a wiring short in the consol for the back lights. Putting the car in reverse (manual transmission) cause the fuse in circuit 10 to blow. Now I have all the brake warning lights (park, fluid and ABS) on and they will not go out. Car operates fine. What may cauing the lights to come on and stay on?

A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a 12 volt light bulb. A brake light bulb works well. When the circuit is live and the short is present, the bulb will be full brightness and hot so be sure it's not laying on the carpet or against a plastic door panel. Now you can unplug electrical connectors and move things around to see what makes the short go away. When it does, the bulb will get dim or go out.
