Batteries are low but charger faults out when the batteries are charged while hooked up to truck, batteries charge when isolated. After charging they will not hold charge while hooked up, truck will not turn over. Batteries are not 1 year old yet.

Re: Batteries won't charge while wired to truck
Hi, seems that your alternator diodes are faulty.
You can check this by disconnecting the radio & switching off all interior lights etc.
Then remove one battery lead.
Then get an amp meter and connect it between the battery & the removed lead.
If you get a reading the alternator is drawing current , hence faulty diodes.
The alternator will still charge the battery when the engine is going but then discharges when stopped.
Also check your batteries with a hydrometer by checking the battery acid in each cell as you could have a dodgey cell in them.

Have the new battery load tested, I have seen defective batteries, that goes double for non factory batteries like Autozone and other discount parts stores. If the battery checks out and it is just low on charge you most likely have a draw in the car's electrical system, that is to say something like a vanity light or interior light is on, that light can be a trunk light, a sun visor light and so on, check them at night. Put a charger on the battery if it is just a low charge problem and then find the draw
check connections and wiring on and around battery if corrosion or damage - a fully charged batteries current will not flow correctly --check that charger is working correctly--have battery tested most auto stores offer this service for free more than likely battery gone bad and not holding a charge
A solar powered electric fence energizer usually contains a battery for energy storage. The solar panel collects the energy from the sun and charges the battery. Lead acid batteries, which are used in solar fence chargers, typically last around 3 years, or around 1,000 days of charging.

Start with the basics, here. Check that battery cables are not loose and are CLEAN, on the battery AND the starter. Beyond that, check the battery charge with a volt meter. Fully charged should be 12.5 volts or higher, you will lose starter spin at 10 volts. If the battery is low, hook it up to a charger and charge it up completely. If you don\'t have a voltmeter, go to the store and buy one. If you\'re going to try and fix things like this, you have to have one. If you can\'t do that, remove the battery and take it to someplace like AutoZone. They will charge and test the battery for free. If you can\'t take the battery out, or don\'t have a friend that can, have the car towed to your mechanic.
Here\'s the thing- I can\'t tell you exactly why, but some cars you just can\'t jump start. Happens more on side mount post type batteries. Because you can\'t jump your car doesn\'t mean it won\'t start with a fully charged battery. Now there are other things that could be wrong with you car, that it won\'t crank over and start for you.....but we begin the diagnosis with the battery.
you have a battery charger, throw them on charge overnight. No more
than a 3amp trickle charge. If you can charge one battery, and you can
jump the truck by hooking the other battery to jumper cables, then you
have identified the problem as low/dead batteries.
PSD's make a lot of noise on start up. A difference you will notice
between the cumming and the psd engine at start-up is that the psd
cranks longer. This is due to the fact that the fuel injectors on the
psd are actuated by oil pressure.
Many new batteries will come with bad cells from the factory. If you just purchased this, I would definately try returning it asap. As soon as you get the new one, immediately hook it up to the charger to see if you have the same results. I have heard of others who have gone through two bad (new) batteries before getting a good one.
