This 12V Dynalite unit replaces the Lucas C45 dynamos for use in positive earth applications. It has an output of 40A compared to 25A of the original and weighs 3.5kg, compared to 6.0kg originally. A C45 for negative earth applications is also available.
To ensure that the dynamo on your vehicle is a C45, it should be stamped with 'C45' on the case. If you cannot find this, check the distance between the mounting flanges, it should be approximately 166mm.
Dynalites are not supplied with a pulley or fan fitted. However, as the shaft diameter of the Dynalite is 15mm, the fan and pulley from your old dynamo will fit. If you do not have a fan and pulley we are able to supply these separately.
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. Wiring diagrams for both methods of connection are shown on this page.
