Upgraded to dual batteries. Alternator?

[Mike6158]

Is there a higher output alternator available that is a bolt in? And is it necessary or desirable?

Yes

And is it necessary

No

desirable?

Yes

Lol Now that I'm thru ordering a L/R pair of the antenna mounts that you're selling

Got specs? Source? (whew... not on your site)

I used a 130amp alternator for the Tundra/Sequioa V8. Just need to mod the connector on the car going to the alternator. There's also a 150amp alternator for the Sequioa if I remember correctly.

Running two Interstate AGMs off a new stock 100 amp alt. Not a flicker or voltage drop (and there should not be).

Yes

No

Yes

AGREED!!

I have a 280 amp bolt in alternator. I don't remember where I got it from and I'm at work right now (don't tell my boss!) so I can't look it up.
And also the same answer for dual batters as Reznunt said.
Note: You don't need a separate bracket for a second battery. Look up my posts on batteries and see how I did it. I may even reference my alternator on there.
The best batteries IMO are Odyssey batteries. I have two PC1200 Odyssey batteries in the stock battery location. They are a little shorter so I use a short section of 2x12 (non-corrosive, non-conductive, sturdy and cheap) and hold them all together with the metal strap used to hold water heaters in place and a turn-buckle to hold them all together.
Bam! done!

Lol sorry for being short with my answers. Not sure what your intended setup is going to be or what your plans are? You didn't give much info other than your general questions.

The early models came with the lower output alternators and work just fine to charge the starting battery. If you plan on adding heavy-draw equipment or a second battery then you would consider a high output alternator of the later models (if you don't already have it) or from a Sequioa. I have dual batteries and I'm using the 100A alternator, upgraded from the 80A. It charges both batteries at 14.2-14.3 on the high side to 13.9 on the low.

There's a controversial thread on here about remanufactured denso's with good info and a lot of bickering. Got mine from autozone for somwhere between $160 and $180 out the door including core charge. You can get them cheaper elsewhere, but I was in a pinch.

Thanks for the order by the way! It should have been shipped today. You're going to love em!

I installed a Slee dual battery setup last week. Right now I'm bogged down by the stereo system... lots of cusswords going on with that @)*$_@#_ If it's not raining tomorrow I'm going to get all of my wiring routed and button the LC back up

I found this (after searching for r2m's thread):
270 Amp XP High Output Alternator - 4.7L V8 2UZ-FE - 2000 - Landcruiser - Toyota - XP Series Alternators - High Output Alternators

All I need is a rod holder and ground (and a lot of money)

Side trip- With the bracket that you sell how do I adjust the antenna for vertical. I have, and don't like, some Comet brackets that "pinch" onto the back gate and they are kind of adjustable in 2 axis.

That's a lot of amps!

It's adjustable fore and aft only. Simple design to allow a small amount of much needed adjustability... KP made one of the two mounting holes a radiused slot allowing you to tilt the mount forward and backward about 5-10 degrees in either direction. I think they did this because different trucks have slighty different lift heights/rakes from front to back.

It's overkill even for the dual Group 31s I have but I splurged on that because I intend to run a line to also charge a trailer battery bank. I ran the stock alt (100A?) in my 2000 LC for years (one Group 31 and two 27s) and the only time it struggled was after running both banks down in a winchfest with batts on combine. It took a long time to get that last 10% top-up on AGM batteries.

The main advantage of the DC Power isn't necessarily the peak output, but what it puts out at idle/low rpms (~200A?). This is great if you're spending days offroad and working the batteries hard with winching/house accessories run with a large inverter etc.

<edit> Also, if you can still find a Mobi-Arc onboard welder, this will run it.

The idea behind the high amp alternator is for the monster ARB compressor that's already mounted under the hood and future:

• Winch
• Forward auxiliary lighting
• Proximity lighting on left, right and rear of vehicle
• Inverter, at least 3000 watt to run an electric chainsaw
• Maybe upgraded stereo

Albeit, now that LED lighting has come down significantly in price, all that auxiliary lighting will not be pulling as much amperage as my last expedition rig which had everything mentioned above and really drew some amperage when most of it was on!

In any case I'd rather be on the long side of amp's and have some to spare than start cooking my electrical system.

Then DC Power is for you. The armature (and entire alternator) is engineered for that output. Beware "overclocked" rebuilt alternators that claim to be high output.

Not sure if you were directing that comment to me or the original post, but yes mine is a DC Power alternator!
