Accessing Diode Bridge
6.20.1 Remove generator cover.
6.20.2 Remove leads Z2 and Z3 from the diode bridge (a), and leads F1 and
F2 that route to the brush assembly.
Checking Diode Bridge
To check the full wave rectifier, follow these steps:
6.20.1 Set multi-meter on R x 1000 range.
6.20.2 Remove all wires connected to rectifier.
6.20.3 Place the meter probes on two adjacent rectifier terminals and check
resistance value.
6.20.4 Reverse the probes and recheck.
6.20.5 The meter should indicate low resistance in one direction and a high
resistance in the other direction.
6.20.6 Repeat this procedure for each adjacent set of terminals on the rectifier
until all four diodes have been checked.
