Back when you did the Six Gun 7.3 I was using Mecmen Alternator for older Brush trucks. At the time Most Volunteer fire departments were using pickups trucks with skid units. The halogen light bars, strobes, wig wags, sirens and other halogen lights were frying Batteries and Alternators. Between your Six Gun and Mecmen I was looking like the Firefighting hero mechanic too. Thank you Gale.

Had one of these in my old 3.6L Dodge Avenger with 2 optima yellow caps. I jumped everything from pick up trucks to diesel box trucks with that set up. One time I saw a duramax pickup trying to jump his buddy. I ended up jumping him. The look was priceless.

Gale, Thank you for explaining certain concepts, valuable for the masses that needs more amperage. GM even produce a coolant cooled dual stator alternator for a number of years. The alternator supplies the amps required for all the accessories including engine operation, but a rear steering system by itself can use a lot of current to turn those large axle loads. I started using voltage about 45 years ago while working on EFI vehicles with way less demands. While running, and the circuit is on, in a series circuit where the device uses the available voltage. This make fast, accurate and easy for a tech to identify area of higher resistance which is the root cause of a liquid loss of voltage, resulting in lower current. Undersized wires, bad switch, connectors terminal, fuse holder or the device itself can be quickly identified. With a complete system accounting for every amp, every while under full load is an excellent way of finding total amperage requirements plus having 20% extra is perfect. It is very smart to have a ground lug on the alternators frame as ground is created there, as most everyone thinks it is just positive amperage. Although, as posted below by “Dieselman” eluded to “Oxygen Free Copper” wire, is has a little less resistance per foot and the insulation makes it more flexible, but this is represented in the price. Just follow published charts for amperage over length, as they proper use the cross-section of copper stands bundled together, and leave some wiggle room as well. Thanks for explaining a great deal of good information. Get a good digital multimeter and a good amp-clamp, then learn to use them! ASE Master Tech since 78 - Retired.

This guy explains all the questions I have. Without even asking. 👍

Awesome alternators ...most car audio guys use these some even use up to 5.. just a tip use "OFC" wire rather than "cca" and the higher quality car audio wire is super soft and flexible even when using 00 wire

Awesome video as always!! I run a 370 amp 6G 6 phase hairpin alt on my 99 Crown Vic Interceptor. Also running a 1.9 inch overdrive alt pulley. All 0 gauge high strand OFC copper cables.
Big 4 wire upgrade also. And yes, part of the Big 4 wire upgrade includes a 0 gauge cable from battery NEG to the alt case. Because, the true ground is the alt case. Great stuff Mr. Banks!!

Your comment section is on point also. Mostly positive guys happy to digest the info. And many people adding more info.

[russellbergersen]

I love the fact that it is wired for one wire out of the box. Looks like this would be a good swap for older farm equipment that uses electrical accessories on the implements.

What do you mean, "Is going to be a great project"? It already is! Keep them coming!

Technical comments. FYI, 6 phase is 3 phase with each phase center tapped. This does permit using 12 diodes with current distribution in a full wave bridge rectifier. It is wired similar to a Y alternator with the centers of each winding connected together and floating instead of just one end tied together in a traditional Y. Each phase is 120 degrees apart for the prime side of each winding and the 180 degree compliments of each phase connects to the 2nd set of 6 diodes. This configuration is common in welders and other high amp DC supplies to reduce ripple. Primary is 3 phase. By technical definition, this is actually 3 phase with complements. This requires no special alteration of the field. The big advantage is more diodes to share high current and lower ripple voltage.

I'm just glad you're still pumping out content during this pandemic!

It’s so nice to see some one get fired up by an alternator 😂

[bryancondrey]

Mr. Banks, Consider using fine strand welding leads v/s the (0) electric cable. More conductors and less resistance. Don't forget you proper sized fuse.

[ryanburbridge]

So freaking awesome. Absolutely the best YouTube channel now. The different topics and products on display are epic. The graphics and explanation are on point. Thank you amsoil and thank you folks at banks behind the scenes. That old guy is cool too...

[senditsamuel]

Please for the love of God, connect that blue sense wire to the battery where it's suppose to connect, don't leave it on the charging stud. I wish Alt builders would really break their habit of putting it on the stud.

Best alternators period! Nice craftsmanship too.

[johnclark]

Gale mentioned copper clad aluminum (CCA) wire. I use 1/0 tinned oxygen-free copper (OFC) in my truck. OFC is heavier and costs more but it carries more current than CCA for a given wire size and length. I suppose that it may be overkill for how I use it but it is less resistant to current flow and offers additional safety (in theory anyway).

[AnthonyJ]

Low voltage may cause devices to also pull more amperage, possibly causing more heat or damage to sensitive components.

[RobFRC]

I ran a 270amp Mechman alternator in my car audio grand prix for many years with no issues. Put out way more than advertised power. Pressure washed the engine bay all the time without covering it too.

gota love gales comments quote thats buzzin the snout out of one of these things
