I am in the process of re-wiring all of Papa Smurf...well at least most of him. And I need to make sure I have the right gauge wire before I get started. I've already ripped out most of the non-essential wires, and want to replace a lot of the wires I already have, and insert a bunch of weather-pack connectors to make working on it much easier.
so, here's basically what's left: Ignition brake lights gauges fuel pump accessories (cool suit, radio, etc) signal wires (oil temp, oil pressure, tach) Can I use 14 gauge wire on most of these, except the main power/ignition? What should I use for that? thanks |

However, the diagrams call out area in square mm, which is the European convention, rather than wire gage, which is the US convention. You'll need to find a chart to convert between the two. |

OK, so if I'm reading this right, if the wire on the Hayes manual says 1.0, that translates to a 17 gauge, I should be fine with 16 gauge wire there. |

Thin wires get hot faster. I would use the 14 gauge. it should be good for 20 amps at 12 volts. use 16 only for the gauges.
