MG MG Y Type - Monte Help: Alternators

For the Monte, see earlier post, I thought I would switch to an alternator instead of the dynamo as I will be running auxiliary lights and a heater. I presume that should be relatively straightforward? Has anyone made this switch? What alternator did they use? Thanks.

I dont own a Y. I am just an observer over from the Midget @ Sprite threads. A friend with a Sprite recently fitted an alternator that is contained in the body of a dynamo. These have been mega expensive until now but he got his from Bad Boy Classics. They are about £150 and are C40 or C39 replacements. The unit has recently completed a 2500mile tour I ran (see www.masckent.org). It allows the benefit of an alternator with the looks of an original.
Hope this helps.

I think if you switch from a dynamo to an alternator you will also have to switch polarity of grounding Marc. Try contacting Richard Prior our Western Australia Representative as he has switched dynamo out for an alternator and he may be able to help you with that conversion.

I have just checked BBC website and they advertise a + earth 'dynalite' alternator for £145. I was under the impression conversion had to be to - earth but apparently not.

The concensus seems to be that alternators are risky with old wiring looms and, if my dynamo is in top condition, and use LEDs, I should be ok re charge. So thats what I will try!

I fitted the Lucas (what else?) alternator to my Y. This is the thread in the archives:
