Rewiring

[Grant Bowker]

Assuming that the conversion to 12 volts is from 6 volts, you could use the same wire guage as was originally used. This has the benefit of less voltage loss in the wiring so that lights will be somewhat brighter and the starter should seem more powerful. Use of "oversize" wire and relays is common in rally cars for maximum light output. The gains of doing this will be most visible on systems that were originally wired with conductors at near their maximum capacity. I don't know of any problems with using "oversize" wire except that it weighs more which isn't much of an issue on a carrier/CMP and costs more per foot which again shouldn't be a large issue given the relative simplicity of carrier/CMP electrical systems.

One caution that should not apply to Ron's question, do NOT try this on 24 volt to 12 volt conversions, potentially disastrous overheating of wires may occur.
