    Redtop Optima is close to dead

    If the voltage is too low for the batteries, it is too low for one or more. AGMs like higher voltages, but most will charge OK with low amperage if you let them charge long enough.

    Redtop Optima is close to dead

    The issue not that the alternator output is "too weak" to charge two batteries, but that the voltage is too low to keep some AGMs happy. My old GMC is running a stock 105amp alternator and it has been charging pairs of Optima and Odyssey 34/78s for 20 years. Those batteries never see a shore...

    Redtop Optima is close to dead

    If it's the red light position, meters will see the system as one big battery.

    Redtop Optima is close to dead

    Yes! That Mechman gizmo has been talked about in several forums, and the Toy Boys seem to like it. The Painless Performance isolators are seriously underappreciated. I have them in two trucks, one for almost twenty years and the other for twelve years, and would not do a dual battery system...

    Redtop Optima is close to dead

    Toyotas are notorious for low charging voltage, usually maxing at about 13.9. That is supposed to be too low for an AGM, but I have a Northstar AGM in my Tundra with a stock charging system and everything seems to be working just fine. If it ain't broke, don't fix it. The advantage of the...

    Redtop Optima is close to dead

    Yes. You can charge and desulfate with the battery in the truck and connected. If you get to the point where you want to do a full reconditioning cycle, it is advisable to disconnect the battery from pos and neg cables so it is isolated from the truck's electronics. This is to protect...

    Redtop Optima is close to dead

    That is way below a full charge for an Optima. Resting OCV should be 13.1 or 13.2 at 100% SOC, depending on whether it is a Red or a Yellow. Short trips might be sulfating your batteries. As pointed out by another poster, Optimas respond well to conditioning charges on shore power with an...

    Redtop Optima is close to dead

    In that application, the Yellow would be a better choice than the Red. You should also be able to fit another 34/78, like an Odyssey 1500 or a Northstar. My battery boxes are generic, but all my holddowns that work with Optimas also work with Odysseys as long as the terminals are in the same...

    Artic Cove 18 volt Mister

    It was 111 here on Tuesday and I was working outside, so I bought one of the Arctic Cove Misters. It does cool things down, but leaves a lot of things wet in its path, even with the fan on high and the pump on low, feeding from a bucket. Seems to need higher pump pressure or higher fan speed...

    Dual Batteries Charging System

    Depends on the battery. Optima has detailed charging specs on their website. Toys are notorious for low charging voltage off the alternator, but there are gizmos available from some of the Toy specialist shops that step up the voltage to be more suitable for AGMs. My 2008 Tundra has stock...

    Sand ladder / dog ramp.

    When I bought mine, the 60" aluminum mats were very hard to find. There are some steel landing mats available, but they are heavy and unwieldy. OK Offroad may knock off a few bucks and give you free shipping, sometimes they run specials on these mats. You might look into fiberglass industrial...

    Sand ladder / dog ramp.

    OK Offroad has 60" aluminum sand ladders. If they are too slippery for the pooch, you can zip-tie some carpet to one of them, easily removed if you need to use them for an actual recovery of the vehicle.

    Sprinter, Nissan, Ford or Dodge?

    There used to be a lot of threads on this site about Sprinter camper conversions, with lots of build details. Worth reading if you can find them. A friend of a friend switched about three years ago from an F-350 cabover to a Sprinter, and he loves it. If an E-350 is large enough inside, I'd...

    SnoMaster Fridge/Freezer Review

    Probably because at least some of the Whynters are actually SnoMasters. One of my Whynter 45s is labelled as "Whynter by SnoMaster," and the other is labelled simply as Whynter. They are otherwise identical in every visible respect.

    WTB - Portable 12v Fridge Unit <$500 within 1-200 miles of PDX, Or

    Just went back and checked. I paid $237.50 each for the Whynters, but it took some negotiating and standing there waving a wad of cash at them. Buying two at the same time didn't hurt, either. These guys had a pile of Whynters there, mostly the larger ones. Mega Appliances Tel. 562.926.5500...

    WTB - Portable 12v Fridge Unit <$500 within 1-200 miles of PDX, Or

    I bought my Indel B 50-ish for about $540 delivered, brand new. Try WestyVentures. There are dealers who specialize in so-called "scratch & dent" products from companies like Whynter I picked up a couple of S&D Whynter 45s, new with warranty, for about $225 each a few months ago. At that...

    Decisions on a 12v fridge

    I have had an Indel B for about three years and love it. When I needed more occasional capacity for my buddy's fishing trips, I bought two Whynters because they were cheap as scratch/dent units at about $225 each. The Whynters have been fine, a little loud when running and a little heavy, but...

    DIY Maxtrax bag?

    Go to Craigslist and find a cordura bag for an electronic keyboard. Only took me a couple of weeks to find one that fit my MaxTrax. You get full length zipper, handles, padding and room for other miscellaneous stuff.

    Power Wagon common problems? Best years?

    The best year for modern PWs is the 2005, but finding a clean, low mileage example might be getting difficult. I own an '05 and it is, by far, the best truck I have ever owned (and I also have a Z71 and a second generation Tundra). In close to twelve years, the only issues I have had have been...
