Can a voltage regulator be adjusted?

If the voltage, at which the reading becomes steady, occurs outside these limits, adjust the regulator by turning the adjusting screw 1/4 turn at a time clockwise to raise the voltage or counterclockwise to lower. The adjusting screw can be found on the back of the regulator facing the firewall.

How does a Lucas regulator work?

When the dynamo is giving less volts than the battery, the regulator disconnects it from the system so that it cannot draw any current. This reduces the magnetic field strength in the dynamo which reduces its output voltage, thus regulating the charging voltage supplied to the battery.

Can an alternator be adjusted?

It is possible with a simple resistor voltage divider to externally adjust any alternator with a sense terminal to produce a higher voltage – no alternator modification is required. The circuit attached is designed to increase the alternator voltage to 14.5 volts.

What voltage should my alternator be?

A good alternator should put out between **13.5-14.5 volts. Stress test the alternator – Place a load on the alternator by turning on the headlights, the radio and the air conditioning. The voltage should remain high with these circuits on.

Where are the brass adjustment screws on the rb106?

NOTE: The two brass adjustment screws with the springs, on the rear of the RB106 metal frame, are ELECTRICAL ADJUSTMENTS. These are not touched when doing the contact removal, cleaning and re- assembly.

Is there a description of the function of the rb106?

A description of the function of the RB106 is published in the first pages of the article on Experimental Electronic RB106’s on the worldphaco.net website, so that will not be reproduced here. This paper is a series of notes and photos on how to repair and get the best out of the original RB106.

Does rb106 have oxidation on the voltage regulator contacts?

Any RB106 unit that has been used or has been kept in storage will have oxidation on its voltage regulator contacts and to a lesser extent on the cut-out contacts. The manual suggests cleaning the voltage regulator contacts with a fine carborundum stone or silicon carbide paper.

Are the workshop manuals for the rb106 any good?

The standard workshop manuals are basically good in terms of describing how to service and repair the original RB106, however there is not a lot of detail on how to physically do it to get the best results and good reliability.
