1) Using ohmmeter, check continuity between each of upper and
lower rectifier bodies and each diode lead.
Check both directions by reversing probes of ohmmeter and
there should be only one-way continuity in each case.
If check result is not satisfactory, replace rectifier.
2) In the same manner as described in above step 1), check that
there is only one-way continuity between both leads of diode trio.
