Alternator of choice? - Page 3

Wiring is not at all my strong point but it's regulated far as I can tell, and has EFN spade terminals plus the main battery/output post.
I'm thinking this below but if it looks wrong to anyone do please shout! -

E - Earth
F - Field - green wire from regulator (DF)
N - Stator - the dashlight wire, the thin red one

On the output wire to the batt/solenoid I'm going to put an inline fuse in a weatherproof holder.

the Nippon unit does have a built in regulator... cant upload any photos yet, as car is outside my brothers house... i'm off on hols tomorrow!!!

A day of brain failures and car failures. Figured out my ND alternator as referred to earlier does not have an in-built reg. So I hooked it up to the stock reg, but that's dead. Shame because the alt was dead easy to install.
So faced with either replacing the reg again or faffing with another type, I got a genuine ACR cheap. Square one again.

If your ND does indeed use a separate regulator (see below) it will have to be specific to that alternator or similar ones in the ND family. The 3 makes that Volvo used also have to have their mating regulators.

A bit of searching around finds this. Read down through the thread.

Going way back i remember there was a three pin SEV Marchele and a Bosch regulator , one was supeceded to the other later on in the cars life . the function is the same which ever alternator is used . The regulator just adjusts the rotor current to keep the charging voltage between 13.8 and 14.2 volts , with temperature compensation of course .

I thought regs were regs, on bikes we swap them about, so long as the wiring can be figured out. Although I'd wanted shot of reg and dynamo both, for money sake and getting going I'd have used the ND and external reg if the setup worked.
But I decided it was as well to find an ACR as buy another reg, so I've done that. Live and learn (if slowly in my case).

Alternators produce AC and dynamos DC so use different regulators to give DC to the battery. I expect you've had relatively modern bikes as early ones, up to the late 50's used dynamos. Triumph fitted an alternator in 1954 to their big twins which was a useful for the police bikes with their radio equipment.

There you go! I'm not safe around electrickery - if it can't be hit or coloured in it's beyond me... Should really have realised that. Didn't even stop to think. Once I'd realised the lack of reg I just hooked up wires because they seemed invitingly to match. Oops... Praps if it was like bikes with three outputs a penny would have dropped (but praps not!!).

Had all sorts of bikes, but yes reg-rec swapping on alt-equipped ones, old Suzukis.

Off to beat myself up with the electrics green book.

I my carefree youth I mixed and matched all sorts of Bosch and SEV alternators and regulators without any problems. The solid state Bosch ones seemed to be the most reliable. Cheapest regs are the aftermarket ones by Lucas and others. They come with wire connectors for various alternators and work fine with Bosch or SEV.

Here is the denso one i am using in a 544. Direct bolt in with internal regulator. Pretty small footprint but only 40 amps.
