X4075 (20) ELECTRICAL CIRCUITS ON "GOSHAWK II". Owing to the various troubles they may arise through the blowing of fuses, I have come to the conclusion that the following is the best and simplest scheme that we can adopt. Relative to the battery the switch box comes before the fuses, and is protected in case of short within it, by a buzzer contact breaker (like Delco) or thermal breaker (like Remy). Much of the distributing is done in the switches where the wires leave for the distributing fuse and terminal board. There will be separate fuses for (1) head lamp (2) side lamp (3) separate fuses for the dynamo field (4) and armature (5) ignition circuit (6) body, klaxon, gauge lamp and connection socket. There will be fewer wires to the switchbox, but more to the distribution board (this is preferable). Diagram shewn explains this is a new arrangement, and the distributing board requires rearranging. The buzzer etc. is better than a fuse because it does not entirely break the circuit, it being very undesirable to do so with inherently (third brush) controlled dynamo. With a vibrator regulator on the dynamo the arrangement is much more flexible and can be the simpler scheme previously suggested, but at the moment we have not a good regulator available. | ||
