I am about to re wire the engine bay of the HT, are the following wire sizes correct.
Battery + and- lead 10mm2 wire
Alternator and ammeter 1mm2 wire
Gauge sensors and general wireing 0.75mm2 wire
Driving Lights 2 x 100W 1mm2 wire
Any dramas with these sizes.

Automotive cable is not the same as household cable in terms of the cross sectional sizing. 3mm multi stand single core is what is mostly used under the dash and to lighting circuits and alike. Best you look here http://media.narva.com.au/books/10.pd

hey bredbo.
i am not sure about the battery and alt wires,
but for most of my wiring i used 240vx15amp power lead, bunnings 15$ 25mtres with 3 wires, easy to strip,
far cheaper than auto wires, and takes more load than 12vx15>20amp auto wires, it i |

1sqmm cable is only good for about 15A with air circulation. Whack it in an engine bay where its hot and un it with other loaded wires and it can only carry less. 200W of lamps is about 16A, so id be looking at something closer to 2.5sqmm. Ammeter and alt |

I was going to post something similar this morning - do you mean total wire diameter or sqmm Bredbo? Cause they are really thin wires.
For battery straps (starter and earths) I usually go 2awg (35sqmm or 12mm diam) but like HK1837 said 25sqmm is a gre |

Itd only be V75 PVC so not really any good for engine bays.

V105 PVC is OK, that is 0.6/1kV rated. Normal flexible cords are V75 PVC insulation and sheath. The maximum operating temperature of the insulation is 75degC which is normally from current flow in the cable but in an engine bay it is also external. The PV |

hey dok terry,
the copper in the power lead is alot thicker that the auto cable, and the covering is too,
and it appears to be alot more rubbery and flexible than the auto cable?
i know this does not mean it is more suitable, but from experience with p |

For places close to hot items like exhaust manifolds - I would personally use Silicon insulated cable. I use this alot at work for rebuilding Metal Halide lighting fixtures. Its three times more expensive though.

As a licensed sparky I have to agree with Kraul. There is no way I would use any of the cable I use everyday at work under the bonnet or anywhere else in my pride and joy. TPS (2 core and earth) cable will not last five minutes in a car subjected to any o

house wiring is low quality, but power leads are not.

or what grade of plastic it is?
how does anyone know whether it is exactly the same material?? or not, as car wiring.
gee i dont know,
