Hi everyone, alternator issue to ask about,
Its an old 70amp one, Ive had a alternator warning light on, and now its not charging when the headlamps are on. The belt is tight within the haynes guidance
My question is, is it worth trying to refurbish brushes (or any other component?), or, considering I have no experience working with alternators, and a new one is ~£50, am I better off just replacing it (its at least 10 years old by now)

Thanks in advance, Pete

To be honest I’d replace it. By the time you’ve factored into reaping it, any bits you need and the fact it might not work. It’s usually better to replace it. £50 isn’t the end of the world.

When you have fitted the new one, carefully take the old one apart.

 

If nothing else, in a competition, an alternator with half its guts on the bench, leaves that little bit more power to churn the cogs.

That was my thought Alex, just gauging opinions of those who've done it, before I commit my cash!
If it is a simple job Id rather have a crack at it, not entirely sure what I'm doing though ?

Gold Lion Auto Electrics on Ebay will supply you with new brushes, rectifier and bearings for @ £15 and it's straightforward to fit the parts
