car is pretty much fully wired now but small problem with the charge light on the dash not going out when the engine is running. its a nippon denso
alternator and a bright 6 display.
have checked previous posts and pretty sure its wired properly - if we swap the wires over at the alternator end we get no lights at all.
we have checked the battery is chargin by putting multimeter over it and they go up to 14.5v when the engine is running and 12v when its not.
any help appreciated.
cheers,
Ned.

are they led,s?could be the prob,insert a test light in circuit and see what happens
is the light staying on when the ign is off? if so prob a diode failed on the alt
had the same problem with my old car, the led alternator warning lamp was to blame, as said above fit a filament lamp temporarily

It's wired as per this http://www.westfield-world.com/Daihatsu_alternator2.html
When I add a warning light should the other side go to a 12v supply or earth, I think 12v but no light whatsoever when I do that :-(
Normally the 'lamp' wire goes from alternator to dash light and then to switched +12V. The dash light lights when the alternator lamp wire
switches to an earth (when it stops)
As the Bright 6 has an led warning light, does it need an external diode to make it 'look' like a filament bulb?

From memory i think you need at least a 3 watt bulb for the ign warning lamp(acr type). So prolly the same for this one. An led needs very litttle voltage to light it up.
Both wires to the charging light should be hot with the car running. One should be IGN+, the other should go to the alternator and be the same voltage as IGN+. LEDs may be too low voltage to work well as a charge light. The difference in voltage drop would be enough to turn the LED on even though the vehicle is fine.
The Bright6 module does have the extra components to make it look like a filament bulb to the alternator. No extras required.

I should add that if I drive my car at night, I can see that the charge light does flicker faintly at tick-over.
I don't let it worry me though!

It's a real wrestling match to get behind my dash - I only go in there if I have something that needs doing! (It's a 1 or 2 hour job to go
in there, do whatever's necessary and put it all back.)
Sorry!

David,
Purely by the by, I cut the back off my grp scuttle and have put in a removable ally panel for this very reason. i was getting bored of hangin upside
down with my feet on the rollbar doing my back in trying to get to some of the switches!!
cheers,
Ned.

We wired a warning light between the alternator and 12 supply to test the charging light and eliminate the Bright 6 but that does not light at all.
I am convinced we have the wiring correct so maybe the diode in the alternator is knackered :-(
