[QUOTE="Waveguide, post: 914085, member: 364636"] No filter capacitor after the diode bridge? Charging/discharging capacitors without current limiting (resistor) is one good way to fuse relay contacts if the peak currents are high. Easily tens/hundreds of amps for common voltages and sizes for electrolytic filter capacitors. Even if the relays don't fuse the contacts are ruined much faster than for normal loads. [/QUOTE]
