Simple Bus alt question, honest.
Hello
'73 bus, with alternator. Not charging battery. I'm guessing that bulb may have blown, but since its dark when I get home now, its not too easy to crawl about underneath the dash doing my Vet bit. I tried swapping bulbs with another lamp, but the little ****ers wont go back in right. I will get the instrument panel off at the weekend, so to prepare, I went through the wiring diagrams to get my head around it, and now have a couple of questions. On the vintage bus diagram, which is the one arranged by current tracks, there seems to be more than a wire and a bulb at the instrument panel for the warning lamp. Can anyone confirm this. I was under the impression that I was just looking for one wire and a bulb holder ! On the schematic diagram for the '71, which I sometimes use because its got the relative positions marked out, the wire seems to split & go two ways. Again confirmation of this would be appreciated. Thanks James |

The confusion comes about because the Blue wire is also used to test the lamp in the Brake Warning light (K7). But the diagram looks like there is a single wire (Blu) on the ALT light socket. Splice T8 must be part of the Main harness. Speedy Jim http://www.nls.net/mp/volks/ |

focus on the dash warning light. If this is not operational (bad bulb), the
alternator WILL NOT CHARGE. John Aircooled.Net Inc. |

It should, and if it doesn't then there is either a problem with the bulb or it's wiring. >On the schematic diagram for the '71, which I sometimes use because its got >the relative positions marked out, the wire seems to split & go two ways. >Again confirmation of this would be appreciated. The '71 has a generator instead of an alternator, so the wiring concepts are completely different. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |

After scrabbling about in the cold wet & dark upside down with a torch in my mouth, will attempt this at the weekend when I can get things apart so I can actually *see* what I am up to. Thanks for all the replies James |
