I drove the Herald for the first time in a while last night, particularly at in the dark, and noticed that the ign light wasn't going out. Actually, it was behaving as if the car had a dynamo, getting dimmer as revs rose and going out by around 2500rpm. I've just been out to take a look with a multimeter. Wiring and connectors all seem sound. Voltage is about 12.3 at idle (roughly what it was before I fired up) and this rises to about 12.8/9 at higher revs. I'm guessing borked alternator?

Sounds like it... It's worth ruling out the body/engine earth with a jumplead from block to battery first, this happened to me with the zeetina... I swapped the alt first then found the dud strap.

To get a standard A40 this low, you'd have to dig a hole to put it in |

Well, since posting I've found an alternator in the shed so have whipped the one off the car and just swapped the pulley over as the shed one's was missing. No idea if the shed one is any good but will see if it makes a difference in a few minutes. Will bear the earth lead in mind if its still not functioning. Ta  |

OK, shed alternator appears to work  13.5 volts now showing at the battery. So, what might be up with the old one. "Rectifiers" appear to be available for them and if its that that's needed it might be worth my while refurbing it to be a good spare back in the shed again.... |

Yh, it'll be the regulator/diode pack/ brush holder assy depending on which alternator you have.
Depends how tight you wanna be, co they can be had new for about 50 notes
