Leece Neville charge light

[Wrinkley]

I have a Leece Neville 8LHA alternator and would like to fit a charge light. I have been happy to use this alternator over the last five years with out a charge light relying on a volt meter to show an increase in battery voltage when the engine is running. Just like to have a lamp to indicate that the alternator is charging. There are two connections on the back of the alternator +ve and -ve and three AC taps.

 

Any help would be gratefully received.

There is diagram on their website. I'll look later, big fingers and small screen a bit challenging at the moment. Edited November 9, 2016 by Eeyore

Stating the obvious I guess, but in most alternator installations, the lamp goes out when it is charging, rather than comes on when it i charging.

Just use one of the ac taps to drive a changeover relay coil; the relay common to switched 12V off the ignition switch and the NC to drive the lamp.

Curious - the 8LHA is a serious bit of heavy duty kit designed to providing full power continuously - more NBs 'ought' to have that style of alternator. It's the only one I've looked at with 3-phase outputs -

 

What were they actually used for - I assume that they were regulated in effect?

Here you are, just as Davidg suggested

There's a coincidence, I have one in bits on my bench now. You need a regulator part number 8RG2120 which has a warning light terminal.

Thank you all for your help.

 

Davidg for the description, Eeyore for the link to the diagram and Sir Nibble for the part number. I have googled for the part number but nothing came up. I the googled for alternator spares then searched a number of sites for the part again nothing came up. Sir Nibble, do you have a preferred supplier?

[Sir Nibble]

Yes but they don't do that bit! I will have a look

[Sir Nibble]

OK, i only had time for a brief look but if you forget Leece Neville and google prestolite instead (who actually make the thing) I think you will find it.

[Wrinkley]

Still can't find it (nothing unusual there) I will probably go the relay route. Thanks for all your help

[Sir Nibble]

I will have a look.
