Accessories

This 12V Dynalite unit replaces the Lucas C39 & C40 dynamos for use in positive earth applications.  It has an output of 40A compared to 25A of the original and weighs 3,4 kg, compared to 5,8 kg originally. A C39 and C40 for negative earth applications is also available.

To ensure that the dynamo on your vehicle is either a C39 or C40, it should be stamped with ‘C39’ or ‘C40’ on the case. If you cannot find this, check the distance between the monting flanges, it should be approximately 144 mm. It should be noted that the original Lucas C40’s and C39’s were physically the same and it is often difficult to distinguish between them. The main difference was that the C40 had a slightly higher output than the C39.

Dynalites are not supplied with a pulley or fan fitted. However, as the shaft diameter of the Dynalite is 15 mm, the fan and pulley from your old dynamo will fit.

When connecting the Dynalite to your vehicles electrics, there are two options:

1. Use the existing control box as a junction box.
2. Dispense with the original control box and purchase from us a dummy control box which acts a connection box, but also has an integral fuse. The integral fuse, fuses the output of the Dynalite, to protect the wiring of your vehicle in case there is a short circuit within your existing wiring. (This is the recommended option, due to the fusing capability).

For both connection methods, (on positive earth applications), a relay is used to connect the warning light to the ignition supply. This relay is provided with the dynalite and comes partially pre-wired.
