Hi Folks, I'm installing a 260Z Voltmeter in my 240Z. The Voltmeter has a charging light which us 240 owners have to live without.
Has anyone else done this and if so did you just connect the charging light to a 'switched source' and the L lead from the alternator? If so are you 'happy' that if the bulb blows the alternator will still charge? My 'Electrical manual' and the link below seems to suggest otherwise. Has anyone had their charging bulb blow? My manual shows charging bulbs with a 'bypass' resistor across them so that if they blow a small current can still flow.
Am I concerned when I don't need to be?
The alternator relies on a small current flowing through that bulb (from the source) to 'excite' it to start charging. The current flows because of a 'potential difference pd' (voltage) between the source and the alternator. When the alternator starts spinning and charging the pd reduces and the light dims and goes out as the voltage increases.
The voltmeter/ammeter swap seems reasonably easy (I'm removing all my heavy power wiring from my loom).
