I need to replace the alternator in my 78' Clubbie. Is a 70 Amp alternator an over kill? Or should I just stick with the standard 55 Amp? Any recommendation?...

I run a 70 Amp and it's great, no more power issues for me!

Nothing wrong with that. 100+ might be overkill.
I've got a 65 amp and it keeps up with all the spotlights, stereo, and everything else.

I run a 70amp in the mini and in the moke..
I replaced them both under a month ago.

Cheers everyone

Anyone in Perth know where I can get a new 70 amp alternator ASAP?

Repco can order them ,I have just brought one from Rockingham WA branch, they will need to order in , but normally stocked in perth, alternator 12v 70A part number DXA443 retail $359.00.

Its is good enough to light up this lot

It may be overkill from an outlay point of view if you don't need that much supply ,and the cost is remarkably more.

The car will use about 20 amperes at night (2x60 watt globes + aprox 5 Amps for ignition) before you start adding in other loads such as a stereo and other accessories.

However, if you're not asking much of the alternator, then at least it will be understressed through life.

All garage work involves equal measures of enthusiasm, ingenuity and a fair degree of irresponsibility.

My standard 45? amp alternator was enough to power the mini with a modest sound system with halogen headlights and driving lights.

But nothing wrong with more - I'm using a newer 65 amp one for reliability.

Just got my hot little hands on a 70 Amp one from Peter the MG man in Maylands

How much marty

takes you to a well put together, modern, aussie local business, and ausmini member, and is excellent value.

Maths are your friend....

I=P/V.... Add up your power requirements Headlights (200W) Spots (200W) ignition (5W - previous post) stereo ??? wipers???

Say.. 600 divide by 12 (V) = 50 (Amps)

So your alternator needs an output north of 50 A to charge the battery on a dark and rainy night.. If your close the envelope add a bit for losses (heat)....

Good luck, Ian
