I have a 1979 Silver Shadow II. I think the alternator is failing. I believe my car has the voltage regulator in the trunk (boot) near the battery. I generally do electrical work on my cars myself. Is there a general purpose "universal" replacement alternator that will bolt in? In the USA, of course.

Hello

I can only find info upto the 76 cars (using the manuals on the Australian RROC site). It seems that it may well have a separate voltage regulator. These are of simple construction (the wiring diagrams I can see even show the internals of the regulator). The regulator has an additional complexity as it feeds some sort of battery temperature sensor/circuit (take a look at the diags).

If your alternator is failing electrically, it can only be the brushes in the alternator, or a simple component within the regulator. Both should be easily fixed.

If the alternator is failing mechanically (a bearing), then you can get bearings.

What make is the alternator?

Cheers... Rob.

Just a further note

on 'www.ebay.co.uk'

Alternators (2nd hand) seem to go for £35 to £65, and there is a regulator there for £19 (buy now).

Just search for 'Rolls Alternator'

Do any of these parts look like yours?

Cheers... Rob.
