Alternator kaput ?

[MagicWagon]

Hi. All. Am on hols in Wales and I think my alternator may have had it. Alternator light on dash stays on. Voltage at battery doesn't increase when engine running. Measured voltage at blue/green wire coming off alternator when engine running/reved and only getting less than 2 volts. Fanbelt by seems ok. Alternator spinning. Are these symptoms of failed alternator? If so, am I likely to be able to drive far (e.g 150/200miles hope, or am I stuffed ? Thank you.

It could well be the regulator that needs replacing. It's a bit late now but it's always a good idea to carry a spare. If you are on a campsite you could maybe get Brickwerks to post one to the site. https://www.brickwerks.co.uk/voltage-re ... 3-all.html

Aircooled are usually petrol unless there is an Aircooled Lister diesel in the van!

Where does it say air-cooled any way you can run it till your batterys go flat then that it

Yeah I guessed I can run it untill the battery dies, but if I don't run anting else, lights, radio etc, what's a rough idea how far I might get ? 1mile, 10 miles, 100 miles ? I know it's how long is a piece of string, but a wild ballpark guess would be great. I can get an alternator tomorrow in shrewsbery. (About 30 miles).

Why replace the alternator when it could well be a regulator that costs a few quid?

[MagicWagon]

Well, that's as maybe. But I'm on holiday and need to get home. Looks like I can get an alternator fairly quickly (eurocarparts) but not do sure about regulator. Also how easy is regulator to replace with it in situ. I envisage trouble getting the springs back in.

you must be close to me SY22 5DD

That doesn't make any sense to me - you are going to take the alternator off to exchange it but cannot do the same to change the regulator if you cannot do it in situ?

[MagicWagon]

My thought is that I want to get home first, save money second. If I know I can get an alternator tomorrow, but not a regulator, I may as well get the whole thing.
Replacement has no pulley though. Will I need a puller to get the pulley off the old one ?

Aidan. Yeah looks like I'm not far. I'm in llanfair sy21 9ed
