My 1987 190e 16v is haunted by electrical gremlins. It keeps blowing fuses, particularly the one that shuts off battery when engine is off (radio will keep playing, wipers work) and the one that governs the alarm (open a door with engine running, the alarm goes off) and the seat controls. I've had a couple mechanics try to sell me new seat motor or switches but its an electrical problem. Anyone have a solution? A guess?
