I have to admit to being a bit of an interloper on this forum, as like some others, I have a Landy which is sporting a 2.8 TD under the bonnet
Since I've had my Landy, I've upgraded some of the lighting added some more, and then added som more on top of that too. I'm also thinking of doing some other bits 'n' bobs which will increase the electrical loading.
In view of this I've been having a poke around the alternator area, and have discovered a few things. Firstly It seems to only output 13.2 volts at the battery, and 13.8v at the pole on the alternator. At where I guess 1300 rpm to be it is apparrently kicking out about 10 amps, which I've read is about right.
So why is the output voltage so low? I know it's within spec, but only just, and I'd like it to work better than it does. I guess I may need to replace the brushes and clean the contacts but is that likely to fix the problem (I don't know very much about alternators - in fact there's quite a lot of things I don't know too much about
I assumed the VR was internal to the alternator, but I've also read that this is external - is that the black block that's on my inner wing? it's a couple of inches square and I think the wiring plug from the alternator may end up going into it.
Is it worth servicing the alternator or should I just upgrade to a higher output model, and what have others used in place of the OE one?
Sorry for so many questions, but I'd really appreciate any answers - especially keen to hear about upgrades
