Thank you for putting the link in description

Very informative

Well said ,resister is a must if you have a alternater gauge and no light ,it will burn out the regulater in a few days it happened on my 79 TA,ask me how i know

Nice video thanks.If hooking up the gen light on the dash of a 78 Camero or any other older car which alternator wire would you hook in to?

I have an assortment of 1/4 watt resistors. I would need to combine 2 1K ohm resistors in parallel to get the wattage up and would make it 500 ohms. Would 500 ohms at 1/2 watt be fine? Will the 30 ohms make a difference or is it close enough?

I understand the si series do not need a resister,would you know if everything cs130 up does need a resistor?

Thanks for the help and I seen someone else added two and it made almost 16 volts so I thought that was unbelievable at first and he showed what he did the other wires like the s going to battery u switched and the f wire bulb in dash with power from key going to it and the wire with the resistor that’s what I have did to my GM denso I have on a seperate charging and battery circuit for a stereo system it took a few Toyota wire diagrams and GM also dodge but I finaly got it to charge but do I need any of the other wires or can I just hook that yellow resistor wire to my key switch ? Thanks again

Very interesting video and thanks for uploading. I didn't think resistors could be crimped? I thought they had to be soldered together?

It just need to have current pass through

I have a 03 ford expedition and i got a ho alt with a different style connector the alt is self exciting but voltage does drop when i come to idle going from 14.5 to 12.5 when idle also kicks on the check chargingvsystem light on my dash any help would be appreciated

I have a plug and play for my alternator but my question is where does the black wire go? yellow is hooked up and blue wire goes to alt positive post.

How many volts should the wire be putting out with the resistor inline?

Where does the alt turn on wire go when alt is bypassed and has no plug hookup?

Question? So take that wire and connect it to the second alternator? So if you have 3 connect the wire to the other wire of each alternator

Do you put that wire with the resistor on the alternator positive to install ??? Cuz I saw a vid with a guy who had a wire right there?

Hi there, i have a new gm 4 wire alternator and i did connect the small wire directly to the 12 volt for a few seconds but it didn’t charge at all, will this be enough to fry the regulator? I’m currently waiting for the resistor from Amazon so I can copy what you did here!

I just installed a pcm bypass on my 300, and it popped the resistor as soon as we started the car. Unable to figure out this problem

Can u add a resistor in a alternator that was beefed up from a alternator shop that repairs them

Which way does the diode have to face ??

How long does does the regulator actually last without the resistor? Also does it have to be specificity the 470? Like will a 680 work?

How many volts is the resistor limiting to the alternator regulator? Is it seeing 8 volts 6 volts, 9 volts?

I'm useing the 470 ohm 1/2 watt resistor, but I install in between I grab my voltage tester and still reads what stock alternator is pushing out I'm installed a secondary alternator please help,

Since its not stock plug, if i was to splice and saulder to my harness do i need to use a resistor still? (Dude with the mitsubishi 03 es you should know, whom diss be aha)

Can it work my Honda odyssey’s touring alternator

Do you. Have a wire diagram to install a brand x alt as a secondary? Another question I’ve seen a 1n4007 diode inline on the S wire too well that work on the brand x alt as well ?

You’re watching the video of how to wire a secondary alternator

Why is it necessary to bypass the sensor?

Why is it when I check my resistor in line with my multi meter it still reads same voltage as my battery? Purchased 470ohm 1/2 what resistor off Amazon..

I have a singer 370 with the plug that comes with it I can't get it to charge

This video may be the answer to my problem with my H.O. alternator. I’m very new to this and have watched a ton of videos that went over my head and this one I get to an extent. However I’m not sure if it fits my scenario. If you can help me please let me know. So, I have a 2005 GMC Envoy 4.2 liter. I purchased a 370 amp alternator that was regulated to 14.8 volts from CES in Cleveland. It only worked for a day and then the battery went slowly down from 14.8 to 12.5 and under within a week. Drove out there and on the bench it worked. Didn’t though when I reinstalled it at home 200 miles away. Eventually I shipped it back to them and again they said it works. It must be an error on my part or the vehicle. I changed the belt to 1/2 inch and 1 inch shorter, changed the pulley tensioner, the alternator fuse, running 4/0 power and ground for the big 4…nothing. The plug has 4 colors: Yellow Blue Red Green. Blue goes directly to alternator positive stud. The rest go into the adapter that plugs into the OEM plug. I am not sure if a PCM from the vehicle is messing up the alternator, as it did work for a day or two initially. But I’m at a loss. Apologies for the long description, but if you or anyone out there reading this can describe or point me to a how to video to correct this I will be truly grateful!

That vehicle doesn’t need this done to it. Very likely the regulator just doesn’t work on your car properly. Check out our rectifier test video to make sure it isn’t shorted, than order a regulator and swap it yourself. Our regulators work for your vehicle perfectly!

Where does the wire from the L terminal go on the harness side????

What do you do with the other wires

@dominicharness1799

Every alternator is different, but 1 will likely be a ground, another will be monitoring the voltage at the battery, to insure it does not over charge the system, and then 1 is typically the bigger wire that charges the system. Unsure what the other smaller wire would be used for. Hopefully that helps a little bit.

I have a AD244 145 amp alternator in a 1989 Chevy pickup. I am told the bulb on the dash is what add resistance to the circuit. The only thing is my battery light doesn't come on and then go away when I start the truck so I am thinking I need to check on that bulb. Also, I checked the brown exciter wire pin with key on and it was at around 9V. Does this mean I am not getting the correct resistance in the circuit? Possibly due to the bulb? Thank you!

If you turn your key to acc and the light doesn’t come on decent chance something is wrong with the circuit, checking the bulb is usually the first step yes.

Hi how to find 4 wire plug please let me thank your videos

Good video. I have an ls swap. If I run the alternator through the pcm will I still need to use a resistor?

If you’re using a L signal through a computer no, you do not need a resistor this is if you need to run to ignition or a switched source.

Where can u get the resistor from?

why would the resistor be getting hot and not allowing 12v ignition past it when I hook it up.

..although a resistor will get warm as its resisting current, if you get NO voltage through it it is bad

Where the other wires go

Do it matter what way u install the resistor

Resistors are not like diodes they don’t care which direction current flows through them.

Is this a self excite or internally regulated?

@brandxelectrical

Self exciting is internally regulated. A internal regulator can be self exciting. This is not self exciting though.

Sent you a dm on messenger but I'll ask here also. I have 2000 chevy tahoe with a CES 350 installed to factory plug in. If I connect my 2nd alt a CES 370 exactly how you did this one. Can I connect the second alt to the same battery as the 350 which is connected my factory plug. I want them both to power my truck and amplifiers.

Yes, this is just for turn on. Has nothing to do with what batteries it’s hooked up to 😊
