Electrical System Wiring

Rob wired his Fisher Fury R1 from scratch and learnt a lot when designing the Fury R1's electrical system. Many of the techniques used then are being employed with the OSSEV^®:

• Crimp and solder all connections whenever possible, to ensure high reliability.
• Use uniquely coloured wiring between the key elements of the electrical system, to simplify diagnosis should any issues arise.
• Use suitable fuses to provide power to the key elements of the electrical system.
• Use a relay to deliver high current when required and to minimise the amount of high current wiring.
• Use the lightest/thinest wire possible for each given power requirement, to save as much weight as possible. Thinner wire is also cheaper.

All of the cables for the 12V wiring loom are from Vehicle Wiring Products (VWP). VWP sell three grades of 'thinwall' cable:

1. Thinwall 7/0.20mm, 0.25mm², 1.5 amp. Typical applications: Sensors, relay control.
2. Thinwall 16/0.20mm, 0.5mm², 11 amps. Typical applications: Side & tail lights, alarms, reversing & rear fog lamps.
3. Thinwall 32/0.20mm, 1mm², 16.5 amps. Typical applications: Horns, pumps.
4. Thinwall 28/0.30mm, 2mm², 25 amps. Typical applications: Headlamps, driving lamps, rear screen heater, windscreen wiper motor.
