Voltage Monitor

[Tim Wood]

As I don't have on-board instrumentation, I've fitted a very cheap voltage monitor to keep an eye on the electrics. It has 6 LEDs which indicate different voltages. I've bench checked their calibration and they're remarkably accurate, starting dim at first and then reaching full brightness at their specified level. The internals are a small printed circuit board with everything mounted on it which could be easily mounted underneath the fairing with 6 small holes for the LEDs to project through. After 6 months on the bike, it's proved really useful and reliable. (For those who don't know, the older Beemer's electrics are not so good).

These are marketed in Oz by Jaycar Jaycar Electronics who will mail worldwide. It's only A$9.95, p/n QP-2258. Incidentally, their catalogue has loads of usefull goodies including components such as a replacement Hall Effect transistor for the BMW ignition can at A$19.95 and the appropriate 3 pin connector at A$3.45.
