Dual Alternator

[appleyard 0]

Guys

was thinking of installing a dual alternator for my new project. My questions are:

i. My current stock alternator is rated at 60 amps. If I were to upgrade to a bigger alternator, would there be a risk of frying the electrical with a higher current alternator? Or can I just replace it without upgrading my battery to bigger ones?

ii. If I were to install 2 alternator, what do I have to do? Can I just wired 2 alternators together or do I have to add external regulators or relay?

Since its very hard to find bigger size of alternator in my place, I was planning to install dual 90 or 100 amps to my car and also upgrade the big 3. Anyone has more info in upgrading alternators?

1) You shoudn't fry anything unless you move up in voltage. Going up to 16V+ can mess with your cars computer, but amperage will be drawn simply from the battery and your equipment.

2) Good question - you should really contact whoever your going to get your alts from. They should be able to help you figure out whether you need two alts, or or to implement the two.

Why not get one 200 amp HO alternator instead?

Its because my car is so rare that no one ever heard about it. Its a Perodua Kembara which is a clone of Daihatsu Terios or Toyota Cami. Its a mini SUV.

Also a single 90 amps alternator is kinna cheap here and I plan to get 2 of it.

If its the same as a Toyota Camry you should be able to have Excessive Amperage make you one. And if it isn't the same, I'm sure Nate will be able to make you something custom.

He said Cami, not Camry.

This is a cami:

I understand why you can't find a HO alt for it now

you might need to have a alternator place rewind your alternator to be able to produce more amps. and also take a look at your engine with the serpretain belt is and try to visual see if you can mount another alternator in there. like on i visual can see fitting a 300 amp one and i have been told i can if i get rid of my a/c which i think i might even though i live in florida.

I Live in the far east.... Malaysia to be exact. Over here its very hot and humid and A/C is very important for me. The stock alternator was mounted below the engine so I might have a peek and see an extra space for 2nd alternator which I think its possible to do so.

I just want to read more on dual alternator installation and what I should do as the last thing I need is fire in the car.

i used the bracket for my a/c commpressor worked out pretty good, i also found this link http://www.caraudiomag.com/technical/0206cae_alternator/

Here you can get what they call "One Wire" alternators, typically a GM as its most common. Anyway, you can mount it on about anything like a car, tractor, go cart....to a drive shaft even in a hotrod or something. The regulator and all that are inside so all you do is ground the case and run the big hot wire to your battery. If you can't get one then I would investigate how yours works, does it have external regulator/etc. You could mount another and just add those items. The alternators should regulate themselves to the draw you put on them....should run at 13.5v or whatever just like the one does now except could handle twice the load in amps. You will have to get enough wrap around the pulley with the belt, you may have to add an idler to do that and of course a longer belt to fit. Another way is to add a pulley onto something like the crank, on top of stock one, then run just the new alternator to that with an adjustable bracket you can tighten or put another tensioner on. They use huge belts but that is how many kits add superchargers for example.
