Using a 470 ohm 1/2 watt resistor in-line to power a bypassed or secondary alternator from Brand X

This is a little Video showing how you connect the L terminal of the alternator to an ignition or ACC voltage / switched power source of your choice to turn on a secondary or PCM bypassed alternator from
Brand X Electrical.

I’m still pretty sick right now, but I wanted to get at least something out there since people seem to be having trouble understanding my other write-ups. Sorry for being a little hoarse.

I am not affiliated with amazon in any way, just
Giving the easiest / fastest place to purchase that I’ve found.

They’re not expensive, but are very important to the connection / life of the regulator installed in the alternator.

You can always directly solder the wires vs these solder crimps as well, I just prefer to use them for the volume of them I build daily, and another layer of heat shrink over this.

Any other questions be sure to fire away in the comments! Always happy to help!

Thank you for putting the link in description

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

[dlawson]

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?

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

[steverichardson]

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

[miguelcampuzano]

Which way does the diode have to face ??

[michaelmclachlan]

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

[markpollard]

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..

[budgetaudiowithJ]

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.

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

[slojoegtstang]

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?

I have a GP 370 amp alternator that has a two prong plug and not the four prong one. I’m trying to find out how to make the connections properly. It is a GM alternator and I believe the guy said that it was for a 07 Suburban. Please help me figure this out before I go crazy

[aguiem]

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,

[TheSpazzattack]

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)

[Grownman]

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

[quevicular]

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

[ramhernandez]

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!

[spencerearl]

Why is it necessary to bypass the sensor?

[vikinghauler]

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