This can be found in the Figure 35.1 shows typical amp draw of accessories that the charging system might have to supply. Connect the voltamp tester to Paragraph 41.1 is added. 41.1. Alternator (Army Model MHE 223) The alternator output voltage should be checked using a (1) Connect the model VAT 20 VoltAmp Test Set to the alternator as shown in figure 41.1. (2) Disconnect battery /I F/ufce 1410 AC/DC current clamp is clamped around the altemator's output wire. millivolts (since this current clamp's output is in millivolts), the amperage reading should be within 10 percent of the alternator's rated voltage output Courtesy of If this.is the case, perform the same test on the ground side of the alternator.The DMM is capable of performing these tests; however, some shops may have electrical test equipment that would work more efficiently than the DMM for specific tests. The measure of current in amps is the alternator output in amps. Forthis If reading at M7 (2) exceeds 3.7 V dc, go to step 11 to continue test. • If reading at M7 (2) is 3.5 ± 0.2 V dc, test alternator output and voltage protector. (See next step.) (A1) AMMETER 0 50 AMP (M8) MULTIMETER 0 50 V DC 12 ED If it does not, there is no alternator output; check to see if residual magnetism in the rotor has been lost. POS R I Ground terminal Output terminal “I” terminal “R” terminal + –.Alternator Battery ammeter reading is within 15 amps of its specified Follow this procedure to perform an alternator output test: 1. Inspect the alternator belt condition and measure the belt tension. Adjust or replace the alternator belt as necessary. 2. Connect the voltamp tester to the battery terminals with the charge test. If below maximum t15.5 volts for 12 volt battery or ".75 volts for 6 volt batten" at t0 and "5 amps, charge rate. Slow charge at 1 amp/positive plate. Replace CHECK voltage output at alternator output (BAT terminall. CHECK If no voltage is present, check for broken . or shorted wiring, a bad indicator bulb. a bad fuse in the fuse panel. or a bad connection at the ignition switch or.on the battery With battery disconnected, disconnect the wires from the alternator output terminal and the alternator field terminal.
