Make sure to remind people not to damage the enamel of the coils when removing the stator assembly, if that enamel gets damaged they get a short and the coil is ruined. Not saying never to remove one the way you did, just remind people not to be brutal about it.

Not realy, problem is even stock alternators can overheat with highload at low RPM like engine ideling, that is not a problem in a normal vehicle. But for RV that can be an issiu if you want to charge the battery while ideling. You realy need to change the whole alternator or you might get bad luck, get stuck in traffic with a nearly empty RV battery and toast your alternator to death.

I need to get more power to my car audio system. I have looked at buying an alt but cant find any. The one I have is only 100 amp but can get a 120 amp. Is there any way I can modify it to double the output? Thanks

[@Pkdimmock]

@best butter I have looked high and low. My Vauxhall Astra has a 100amp alt. I can get a higher 120 amp but that's it specific to my car. Not sure if you can get a 160 from another car and make it fit. I have emailed Mechman and Singer and they don't do Euro car alts. The only options that I think I have are to fit a dual alt so would need to find a mounting kit and longer belt or to modify an alt to put out 200 amp (240 if I can get a second hand 120 amp and modify)

Thanks for making the video! I have a quick question for you, i have a PowerMaster Alternator 58302. It's a 220 amp 14.8 volt power alternator 2 pin style - L/F. I had it originally hooked up as a one wire alternator because that's what it said in the add when i bought it but have since found out it's a OE style unit. I've only gotten 13.4-13.8volts. How do i make this thing work?? It's a super expensive alternator and brand new. Do i need to change the regulator out? It's going from 13.8, 11, 9, 0, than back to 13.8 on the voltmeter then on repeat every few seconds, I have no ECU. Any info would be super helpful!

[@yourmommasbackdoor]

Do you know how to find the info to complete this process for a large case Denso 200amp 104210-1630 alternator?

[@yanmarromania8734]

If you connect the windings in series, the power is increased at a higher rpm. At lower RPM, especially at idle, the alternator lacks power and at high power demand, the alternator can burn out. For this reason, alternators are not produced in this way.

[@thedavesofourlives1]

In other words, it's not spinning fast enough for adequate cooling

[@nordic5490]

At idle, low output = low current = low heat.

Check it with a multimeter, if its really that high, the alternator regulator has probably failed.

i fr can't believe this video ain't got millions of views

[@thehumbledabbler]

Very good except I'm hung up on something you said... And I could b wrong bug I don't think so but, it seems that with the wye, or star, configuration, the coils are in parallel with each other, while the coils in the delta configuration are in series.. Further evident by the fact that components in parallel with each other typically hold the same properties, I. E. Voltage, while those components will add on to each other when wired in parallel.. With this principle, I can see how changing it from a wye configuration to a delta configuration will net more power. If I'm wrong then i apologize.

Million thanks in advance for your return on this.

[@TwistTapeTechnology]

I've dismantled a similar alternator, and while it looks like it can be modified in the same way, I haven't personally tried it, so can't confirm that it will actually work. You might be better off finding another alternator and swapping the stator into your alternator.

A standard "12volt" alternator with a different regulator should do what you need. I'm not sure if there are any 6volt internal regulators, so you might have to use an external one.

2 questions i have on this are like some stated about it burning the altenator up or shorting 1. Will it last in a car that sees 6,000 rpm from time to time? 2. Is this a good mod for durability in a daily driver (with a good battery reserve?). 3. Does it have to be rewound for double the power or can you just awind or amp up the output a little bit? Im still learning alot of this stuff myself but definitely interests.

[@paulweston8184]

#1 You have three questions. Not two. #2 I can't understand your first line. Are you saying you have two questions which are about what some other people said about the alternator getting burnt out or shorting? Are you trying to state what the next two... er... um... three questions are referring to? Answers to questions: 1. Will it last in a car that sees 6k rpm from time to time. Sure, as long as you have a good grasp on the fundamentals of electricity, have good soldering skills, and know how to test electronics components with a multmeter. 2. Is this a good mod for durability in a daily driver (with a good battery reserve)? No, it's not a good mod unless you need a high output alternator. I know nothing about your car except that it's a daily driver. You would have to explain why you might need one to justify if it is a "good" mod. Do you have a 3000 watt RMS stereo system that you normally play close to max volume. Yea, might be worth it if you're constantly draining your battery and your headlights are alwasy dimming. It won't be as durable after you modify it to twice as much power as it did stock. What's a good battery reserve? I have three batteries in my car. I consider that a good battery reserve but two batteries are just as good. Three just gives you a little more cushion.. 3. The mod is necessary if you want to gain more output. Unfortunately, I know of no way to squeeze more juice out of your alternator by itself. Uprading to larger power wires will keep resistance low. It's not actually making your alternator more powerful but larger wire will use it's power more efficiently... at least in theory.
