Voltage Regulator Wiring details

Hi,

Would anyone happen to know the wiring details for voltage regulator on 2.8Td daihatsu fourtrak. I've just had to re-wire all my engine bay due to bad wiring by previous owner and unsure exactly what the colour coding is?

I think it is the following, but would like confirmation.
White - Battery
Yellow - Charging lamp
White/Red - Ignition Sw
White/Green - Field winding - alternator
White/Blue - Neutral (alternator)
White/Black - Earth

It's currently connected like this but my battery isn't charging. Only reading 12.7V

Thanks in advance.

Tim

From the wiring diagram I've got, those colours look good, however, mine does list Br (Brown) for the Reg / Alternator 'E' (Earth) terminal.

If you want me to email bits of the manual, contact me.

Thanks for checking the colours for me. I think my diagram originally said Brown but for some reason the earth is black/white coming from the regulator.

I managed to get it working now. It turns out that I didn't have the earth connected back to the battery. I had presumed that it would be earthed through the metal casing and engine but thats not the case!

Thanks again

Full Field Alternator

Submitted by LaBete on

Greetings drivers,

I have an issue with what seems to be my Alternator or Voltage Regulator on my F73.
I have intermittent voltage drops that affect my appliances. AC blows weak, low beam headlights are completely out, radio turns on and off, etc.

I found a testing method of the alternator and voltage regulator, called Full field. It consists of by-passing the regulator and forcing the alternator to produce its full electricity field for a few seconds. Disconnecting the VR and jumping the field connector on the Alt side (white/green?) to the (Battery? white?) connector. Start the engine and measure voltage at battery or at jump wire (16 or 18 gauge)with multimeter. The full Alt field should be 16V if Alt is functionning properly. If it is, it points to a VR failure. If it isn't, it points to an ALt failure.
I've done it and found 13 some odd volts at battery/jump wire.
I thought I could verify my method with you in case I didn't do it right, according to the VR wirign diagram I found here. And if anybody could give me some more insight on my problem.

Anybody?

Appreciated
