what are some good small ones to buy that put out good amps.

that need small mods.

mines a rover one i'm not sure what amp it does something close but smaller would be great.

something like this 55amp??? will there be much between that and my 65amp? nippon ones put out more current then rovers? so better overall?

I have one from a 80's Ford laser

Had it rebuilt last year and got told he had a solid 95A pumpin out of it. Hell knows what im going to with 95A but its good to know i guess.

I have a tiny one from a Daihatsu Charade.. Nippon Denso. I think it does 45A. There's heaps of info on here about various conversions if you search for alternator conversion

The Charade ND one just requires cutting about 5 mm off one of the mounting plates to bring it in line witht the crank pulley.

Pretty sure the standard rover one has a good output about 75 amps from memory. That should be fine for most stuff. If you think you need more than that, you'd be better off going 24 volt (PITA).

i want a small one.. i'm trying to compact the engine bay set up***

smaller alternator are there 65amp small ones?

im going to rub mega jolt, so no dizzy planning on moving stuff around.

making it a much neater set up with my aircon.

maybe even a smaller aircon compressor.

smaller starter motor even..

just small just with high output.

DENSO ALTERNATOR???? looks tiny? what models do they you guys run on a mini?

:)

Is making everything smaller worth the effort? Sounds like you're on an overly ambitious misson to have a smaller starter motor, AC compressor and and alternator given they arent that bad to start with.
:lol:

off small cars, such as Daihatsu charades. There is a whole thread on replacing standard alternator with a charade one of here. very easy to do. You really won't get much smaller than that.

ta dude. found the thread!

Daihatsu charade is there any part number for the 50 amp one where is the best place to pick on up?

i think mins a 65amp going down to 55amp will there be a difference?

what do you have in the way of current draw on your car? big stereo? higher powered headlights? spot lights?

To work out what capacity Alternator your car needs :-
Add up all the Watts that you are likely to use at the same time like Sound system High beam and Driving lights parkers tail lights Dash lights These are all calculated in Watts. Devide the total of watts by 12 and that gives you the AMPS being consumed. To that you will need to add about 15% to give you the total Amps your Alternator needs to be capable of producing.

EXAMPLE:-
(this is just an example different cars have different demands)

Park, Tail, No Plate, Dash lamps 40W
Stop lights 42W
Indicator (One side) 42 W
Headlights Hi beam 120W
Driving Lamps (2) @100w ea 200W
Sound system (Approx) 100W
Heater Blower Fan 80W

TOTAL WATTAGE = 624 Watts

Devide by the Voltage of the system 12 volts

Equals Amps required to run all above together = 52 Amps
To that total add 15% to allow for some charge to reach the battery to keep it topped up =7.8 Amps

Total required output capacity from Alternator. 52 + 7.8 = 59.8 AMPS.

The more accessories you add the Higher the Alternator output needs to be and you do not want an Alternator that is working at it's maximum all the time as it will burn out prematurely.
