My airbag light came on today. i was tracing wires for the low coolant light and had the cluster out. turns out i get signal all the way to the cluster and the light is good so probably bad circuit in the cluster. oh well. while i had the cluster out, i decided to do some more electrical work and had the ignition on at one point. when i reassembled (no extra parts ) my airbag light was blinking . is this because the cluster was out w/ key on? also, does anyone know if the marelli tester used for same era ferraris is the same as the alfa one? i dont mind the light as long as the system is still working.
