TEST PROCEDURE
1.Connect the Analyzer’s Load cable across the CHASSIS battery.
2.Place the Amp Probe around the 12 volt output wire.
3.Set the Volts Selector to Battery Volts.
4.Run the engine at about 2000 RPM.
5.Turn the Load ON and increase until the battery voltage is between 12.5 and 13.5 volts while reading the output amperage.
6.Turn the Load OFF and reduce RPM.

TROUBLESHOOTING
Procedures for troubleshooting cables and connections in the charging and starting circuits are included in the
ANALYZER CARE
•When cleaning the Analyzer and leads, use a mild cleaner such as waterless hand cleaner. Never use gasoline, lacquer thinner, carburetor cleaner, or other aromatic solvents.
•Store Analyzer indoors
•Do not place heavy objects above the case.
UNUSUAL ANALYZER OPERATION
If the analyzer battery clamps are connected to an excessively high voltage the display may blank out. Disconnect the analyzer as soon as possible and shut off the engine.
Check the battery terminal connections visually and also with a Volt meter to verify good connections before the alternator is run.
This situation can happen on a 12 or 6 volt system if a battery cable is intermittently loose and the alternator is running. During the moment that the battery connection opens there may be an over voltage that can be damaging to anything powered by the system. A vehicle battery with a bad internal link can do the same thing, but could also be an explosion hazard if charging gas is permitted to build up and a spark occurs at the break.
In general, if the analyzer is not reading right, disconnect for a few seconds and then try it again. This resets the internal protec- tors.
If the carbon pile is used so much it become red hot, (as viewed through the case side vents), turn it off. Allow the fan to run for few minutes to cool the carbon pile. The pile plates may have to be replaced if exposed to red heat too long. If the pile is used normally it should never reach such an extreme temperature.
SHIPPING:
To avoid shipping damage to the Carbon Pile Load during ship- ment, it is important that the Large Control Knob Be Turned Full Increase (Clockwise) Before Shipping.
