SKU: RSK6001 GP Category:


The RSK6001GP Rectifier Assembly Base is for use on the Stamford HC6, MV6, MV7 and P7 alternators. The kit consists of 2 varistors with 3 negative diodes and 3 positive diodes. The threads on the diodes are all metric and the only difference between the RSK5001 and the RSK6001 is that the RSK6001 has 2 surge suppressors compared to only one surge suppressor or varistor with the RSK5001 rectifier assembly kit. The diodes are clearly marked with red leads for the positive or forward diodes and black leads for the negative or reverse diodes.

Technical characteristics of the RSK6001GP Rectifier Assembly Base

The rectifier converts alternating current induced in the exciter rotor windings into direct current to magnetise the main rotor poles. The rectifier comprises two semicircular annular positive and negative plates each with three diodes. In addition to connecting to the main rotor, the direct current output of the rectifier also connects to a matched pair of varistors, one at each end of the plates. These additional components protect the rectifier from voltage spikes and surge voltages that may be present on the rotor under various loading conditions of the alternator. Diodes provide a low resistance current in one direction only. The varistors can be checked for faults by examining them for outward signs of overheating like discolouration, blisters or melting and disintegration.  The varistors should also be checked with a multimeter. If a fault is found then both varistors must be replaced with a matched pair.

Characteristics of the RSK6001GP Rectifier Assembly Base

The diodes in the rectifier assembly should also be checked with a multimeter after carefully disconnecting them at the terminals. Measure the voltage drop across the diode in the forward direction and then measure the diode in the reverse direction. If any fault is found in any of the diodes they should all be replaced with the full set of six diodes. The diodes should be screwed into the threaded holes in the rectifier plate and 2.6 to 3.1Nm torque should be applied to ensure a good mechanical, electrical and thermal contact is made.
