Two electrical problems
1. Add Coolant Light + annoying buzzer = Headache.

I've tried a new coolant level sensor and made sure the coolant level was actually topped of. Shot the wires from the sensor to the instrument cluster and continuity was good. Checked wire from cluster to the Caution Panel and continuity check was good. Fixed annoying buzzer with a small slash of the contact run on the cluster circuit board that can be repaired. Is there another sensor that didn't make it's way into the schematics? Any ideas?

2. Flashing SB light. tried jiggling the belt and all but no joy. I read in another post that these things are warrantied forever. Is that true? If so, I can take it down to the friendly Mazda place and have them fix it.
