Alternator wiring question. Daihatsu Denso

What needs to go where with this so that I have a working battery light. Obviously I have the large +ve terminal to the battery but what about the other ones?

What goes to IG and what goes to L? I'm guessing IG is ignition live but what about the L and where does the bulb go?

Any use? Taken from a thread I made here

This is your friend - just figure out which you have, or post a pic of the alternator terminals.

So L goes to a 2-3w lamp to earth?

L to ignition lamp to ignition live, not earth.
Assuming the ign light is a proper bulb, not an LED.

I though IG was for a switched live from the ignition? or does L need to be permanant live?


jon200 - 10/2/13 at 10:21 PM

So I need a switched live to both then? Switched to IG and a switched to L via a lamp?

IG is a switched 12v (that helps energise the alternator)
L is your output to ign warning light.

Thats how mine was wired and works fine

Yes, exactly that.

The ignition lights don't always work as you might think.

Mine is the same as the type 4 diagram and all the L does is outputs a signal. It didn't even give enough currrent to light an LED. I used the signal to switch a diode, which then then acted as a relaye to supply a 12v feed to the ignition light.

cool cheers chaps.

Isin't the 12v +ve feed to the alternator light supoosed to come from the Ignition live circuit.
The Alternator is then provides the -ve when at rest and then +ve when its charging.

Thus the light illuminates when the ignition is sritched on but is then is fed with +12v from both sides when the alternator is working n thus doesnt light up.

All this relays and Diodes sounds rather complicated
