Yes almost certainly if it (the rectifier) has gone short circuit, but you should be able to test the rectifier with a test meter; disconnect mains and rectifier, forward and reverse resistance should be low and very high for each diode leg in each direction of test leads (4 diodes if it has 4 wires)
test each leg both ways, or get testmeter with diode test
