Remove and clean all charging system electrical connections (positive and negative). Check the voltage regulator’sharness for continuity. Wires and terminals can and will become corroded, and need to be cleaned or replaced. Ensurethat the regulator’s ground wires are provided with a clean connection to system ground.2. Inspect and replace 10A and 1A ATC type fuses in the regulator wiring harness if fuse appear to be damaged orcorroded. Ensure that the fuse holder is also free of corrosion.3. Charge all batteries to their proper fully charged state, and determine if they are serviceable. If your batteries areflooded-type, use your hydrometer to determine their condition.4. Check and tighten alternator belt. If the belt show signs of wear or damage, replace it. Always replace existing belts withthe finest quality replacements available.If batteries and wiring are in suitable condition, use the following tests to determine if charging problems are a result of a faultyalternator or regulator. These tests provide an opportunity to isolate the alternator, regulator and wiring harness in order todetermine the problem source. In order to perform these tests, you will need an independent DC meter (preferably a digitaltype). In an emergency, a 12V light bulb or test light can be used to help determine if power or working grounds exist. An ampmeter and a battery hydrometer with a thermometer are also helpful diagnostic tools.Voltage Regulator TestingSet your voltmeter to 12VDC and connect the negative lead to the BLACK ground wire at the regulator as shown at the diagramat right.1. With the ignition turned OFF, check voltage on the RED (power), Voltage Sense (Terminal #9), BLUE (field) andBROWN (Ignition) wires in the regulator plug.Voltages should be as follow:• RED wire equal to battery voltage• Terminal #9 RED wire equal to battery voltage• BLUE wire zero volts• BROWN wire zero volts2. With the ignition in the ON position (engine not running),check voltage on the RED (power), Secondary RED onTerminal #9 (voltage sense) BLUE (field) and BROWN(ignition) wires in the regulator plug:• RED wire equal to battery voltage• Terminal #9 RED wire equal to battery voltage• BLUE wire between 4V and 11V• BROWN wire equal to battery voltagePLEASE NOTE: In systems where the ignition (BROWN) wire is supplied power via an oil pressure switch, jump directlyfrom test #1 to test #3.3. With the ignition in the ON position (with engine running at 1,400 rpm fast idle), check voltage on the RED (power),Secondary RED on Terminal #9 (voltage sense) BLUE (field) and BROWN (ignition) wires in the regulator plug. Voltagesshould be as follows:• RED wire equal to battery voltage• Terminal #9 RED wire equal to battery voltage• BLUE wire between 4V and 11V• BROWN wire equal to battery voltageIf voltage is not present on the RED, the BROWN and the Positive Battery Sense Wire, the regulator will not work. If voltage isas expected at the RED the BROWN and Positive Battery Sense wire, and there is zero, or an unexpected voltage reading atthe BLUE wire, contact our technical support staff at +1(360) 435-6100, or e-mail us at balmar@balmar.net.If all voltages at the regulator meet expectations, yet the alternator is not producing charging current, test the alternator. Thefollowing tests are recommended for determining alternator functionality.
