Altenator Wiring

[r-gamble]

I've a suzuki engine corsa b with a vaux Alt, other than the main battery cable that runs to the starter what would the other two finer wires be used for as I don't wire that much and not entirely sure thanks

one for the battery light on the dash and the other will be an earth

Followed the two wires there they both seem to go to the dash where the original display would be !

Would the other one be an earth for the light and run to the dash also ?

The alternator has a thick red 12v to the batt and a blue/white("trigger") wire to the dash board light.

Two thin wires? This is a "three-wire" alternator then. One is ignition light, the other is ignition + used to turn the alternator "on". I don't have access to TIS wiring diagrams at the moment, the 'puter has thrown a hissyfit and needs it re-installing, so I can't be 100% on that. It may not be ignition +, it might be perm live - what colours are those wires. The Blue/White is the alternator light on the dash - that's a fact. What colour is the other one. If it's red, it's perm live, if it's black, it's ignition. Being a thin wire, it ain't the ground!!!!
