Sorry to have either missed it or not read it at all....

What would be the purpose of the second battery?
Any plans to upgrade the alternator (if you havent already done so) and if so, to what?

The reason why is I ask is because of the whole solenoid vs isolators setup.


You mentioned that you were originally looking at the Powergate (already have one myself) and then were switching to considering a solenoid (cost maybe?).


Without opening the fire hose on this one, I offer some simple pros / cons and possibilities



Isolators:

Pros: Simple setup, Less maintenance (generally), Amp rating can go higher, power drops can be lower than Solenoids
Cons: Expensive, Size (depending on model chosen), cheaper ones can burn out

Solenoids:

Pros: Size (Generally smaller), Control options (flexible)
Cons: Amp rating is generally lower, power drops can be higher than isolators



Why the above info?

Simple: use of the second battery.

If you plan to use the second battery for starting (cranking power) in parallel with the main, run a CB or simple stereo, then a solenoid (constant duty) will work fine (remember greater control options) since it gives the ability to control those lower power devices with no issues.

If you plan to use the second battery for high demand power applications (say several amps with subs, air suspension, tons of extra lights), then the isolator (at least from Perfect Switch) would work better since the power loss is a lot less and the isolator can handle the higher current.


Regardless of how you setup your dual batteries, you need to consider the alternator. Even if you have a 160 amp "Big Boy" factory alternator, this will be insufficient in the charging demands. You may have to step up to a 220 amp alternator to allow for both batteries to be charged sufficiently each time you use the truck (and its power hogs).


It all depends on intended usage and frequency.


If I offended somebody because I missed the intended application of Rusty's truck, sorry. I hope this helps just a tad more.

Hey Bubba !!!:cheers:

I do the Solenoid instead of the isolater and I'd also do the Big 3 Upgrade on your charging system and call it good enough. No matter which you decide, I'd to the Big 3 upgrade. That in itself with make your system much better.

I just want to be one of the :quote:cool kids:quote: :cool: LOL JK

I plan on a few more lights, a few amps, a power invertor and a winch down the road and want to make sure I plan ahead and have enough power to run it all. Granted I probably won't be running more then a few of the add ons at one time.

I have a 200 amp/100 amp idle alternator I had purchased from Motor City Reman (don't let the name fool you, they are NEW factory sized ones) and installed for this purpose as well.

You mentioned that you were originally looking at the Powergate (already have one myself) and then were switching to considering a solenoid (cost maybe?).

The Powergate is $300 (I think) my original post shows what appears to be an "adequate" one from the amazon reviews. It doesn't allow for use of the second battery for starting but, it's a fraction of the cost and seems to fit the bill for now. I'm not trying to "cheap out" just don't have the $ (for now) to buy an isolator that cost more then my alternator did.

Can't imagine you offending anyone as you always have knowledgeable input without being condescending:cheers: and it's my thread so fWONk them if someone is.:gunguy: :lol:

That's Easy Dawg !!! You'll have to rear apart steering columns and get the horn rings that are used so the steering wheel can spin. Ferds with Steering wheel Cruise Control option have the same type technology. Just follow that technology and make your own to fit your hubs, then you Got'r Done !!!
