The isolator from www.dfna.info is the simplest of all isolators to install. The “dual sensing” feature of this battery isolator makes it impossible to install backwards. Wiring is accomplished by:
To determine if an isolator is functioning properly you will want to use a volt meter to check the voltage on both sides of the isolator while the engine is both running and not running.
The following are common steps on how to check a battery isolator provided by the experts at www.dfna.info.
An automotive electrical system produces enough electrical power for an automobile to run the ignition system, charge the battery again and supply power for electronic devices inside the vehicle.
Some vehicles take advantage of this extra electrical capacity to sustain a 2nd on-board battery. Typically a vehicle with more than one battery will include a battery isolator in the set up.
Having a larger stereo in your car means more power being needed to run it. Thus, you would need to have a second battery installed. In order to do this, a smart battery isolator is needed. The steps in mounting a TRUE smart isolator are discussed in this article. (more…)
All of the current charging stators in today’s UTVs will produce a maximum of about 35 amps of power when the engine is running at 5000rpm. Many such as the Yamaha Rhino produce less than 30amps.
Battery discharge state at an idle
Understanding this simple fact it is easy to recognize the need for adding a second battery. For example one of the most common accessories is a winch. A common 3000lb winch pulling a 500lb machine through a little mud will drain your average ATV battery in about 3 minutes. If you leave your rig idling it may take 4 minutes. Unless you have an upgraded battery a single winching session can destroy the reserve capabilities of your battery making it useless for winching or hard starting in cold situations.
