I hope this is the cause...
When I drive my car (1987 535is) for about an hour...it's hot in NJ.

When I go to apply the brakes coming off I-95, my dash goes crazy. The tach needle goes up and down, my MPG guage goes up and down. Also, my rear brake warning light comes on. Also, the radio will cut out temporarily.

When I stop the car (like if I go into a store) and then start the car, all is fine.

Is this my SI board and battery going bad?

Joe
