Argodiode Battery Isolator 140-3AC - 3 Batteries - 140A

Argodiode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries. Discharging the accessory battery for example will not result in also discharging the starter battery. Low voltage drop due to the use of high-efficiency Schottky diodes.

The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current, the voltage drop is approximately 0,3 V, and at the rated output of approximately 0,45 V. All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates for the voltage drop over the diodes in the isolator. 

Simply inserting the isolator in the cabling between the alternator and the batteries will slightly reduce charge voltage. The result can be that batteries are not charged to the full 100% and age prematurely. 

Alternator energize input

Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start. The new ‘AC’ diode isolators feature a special current limited energize input that will power the B+ when the engine run/stop switch is closed.

Comprehensive wilderness medicine reference
Format: Paperback
First off, this book should be supplement to actual in-person first aid training and course work. I only have my background in Boy Scouts and work required first aid/cpr/stop the bleed response to base this upon. But there is no substitute for competent in-person and hands on training, even if you have excellent books for reference. That said, this book does have a very thorough guide on most issues that could be faced in wilderness and emergency situations. The cross over for urban use, would be situations like a natural disaster that renders hospitals and EMS unavailable or over capacity. It's a very affordable book for all the information it contains, and is published by a reputable school. NOLS has been teaching outdoors skills since it was formed in the 1960s. If you can keep a level head and have decent reading comprehension, this book lays out diagnostic and treatment advice for many life threatening injuries and accidents. I'd recommend this book to anyone looking to expand and supplement their knowledge beyond basic first aid and CPR.

Had an older edition and bought the most current edition. Very well written.
Format: Paperback
Classic text. Written at the college level. Text treats each topic initially from point of what are the causes of this injury, and how to prevent it. Then it goes into what will need to happen with an occurrence. No pictures, but that's a good thing. There are many drawings which do a better job of highlighting what is important.
