Well done Sir! I can't tell you how many hours of my life that have been wasted watching videos produced by people who should be looking for a better way to spend their free time. I subscribed and look forward to your excellent produced instructional videos.

[@yourboydrewmoney4229]

Best video I’ve found yet thank you sir.

[@josephkritzer7245]

Love the illustration it helped me out

[@josephkritzer7245]

Good job on explaining how to hook up. I have an old piece of equipment and this will work just perfect.

[@mauriciomarino6669]

Well done. thank you.

I connected the 10 gauge battery wire and the red since wire to the alternator post and tested the excite wire it has power. Excite wire not connected to any thing this seem odd to me the alternator will have power 24/7 . Looking at the alt blade connectors they appear joined together. Suggestion?
Great vid

[@fredzeller7320]

How does the amp gauge or volt meter hook up ? thank you

[@garyalford9394]

If I have a 3 or 4 post ign switch I dont need a diode or idiot light right?

[@preacher031163]

I have an 84 toyota 4 runner,has a 3wire plug,and 2 additional wires,im assuming both are grounds?? Wasnt hooked up when given to me

[@legozombiemocmaker8026]

Where do you get the connector kits from

[@gn5673]

would the battery read the same 14.4 v if the alternator is working?

[@altpotus6913]

So if it's putting out 16 volts and the connections are clean, it could be the regulator?

[@rexpetergodwin6185]

How can I know if my alternator brush is bad

[@ericmason2112]

What size are that white wire

[@MechanicForGMCCars]

can you tell me sir what is pin on me 12si alternator? be me I have positive linear voltage regulator inside the dashboard I use only pin 1 with baterry bulb the pin 2 is bend inside the alternator me car dont use that pin.
I have unusual problem when I use hv capacitors on me ignition system the alternator back charges up to 3000-4000rpm the alternator light come up always below that engine speed so how do I counter that problem???

[@Larry-gy9si]

Jay, I'm Hooking up the plyg into 10si the white wire with the diode , the diode was getting warm I had it hooked to a wire that's 12 v all the time , that's not right . I quickly unhooked that wire . Where does that hot wire go to the alternator ? It's 12 v even with the key off ???

[@JamieTransNyc]

plug 2 is 12v always, plug 1 is 12v when key is on

[@duanenevelsii1276]

Will my kill switch shut off my car if i didn't have a dail in the white wire

What’s the benefit of an alternator if an older style generator actually will charge a dead battery and ALT won’t?

[@dennisg7309]

the alternator weighs less and puts out more amperage.

[@dennisg7309]

For a given power output the alternator is smaller and lighter than a generator able to put out the same power. Another benefit is that spun too fast the alternator will not come apart like a generator could.

[@TruckThisGarage]

@@dennisg7309 thanks for explanation

[@krstoner53]

They’re a lot more dependable. My FIL run an auto parts route at the time the alternator’s started getting common and he said the sales dropped drastically compared to the generators. Using a generator at night idling with the lights on most will discharge also

[@garyalford9394]

Will charge at idle once excited !
