The above equation shows that across the posts on the Briggs & Stratton shunt, 1 milliohm equals 1 amp of current flowing in the circuit. This is why the test meter is set to the millivolt range.
Now, lets add charging current from the alternator system flowing through the shunt. Resistance through the shunt will stay the same. We know the current will change. Since the shunt measures voltage drop, we have to be interested in the voltage or pressure in the system. The resistance value of the shunt is set so that we know there is a 1 to 1 ratio between amps and millivolts. Therefore, a reading of 2 millivolts on the meter face is equal to 2 amps of current, 3 equals 3, etc. From this discussion, it should be clear that any meter capable of reading millivolts can be used with the DC shunt.

DC SHUNT INSTRUCTIONS

The DC shunt, part number 19468 readily adapts to standard mount, side mount or tab type battery terminals. The shunt must be installed on the - (negative) terminal of the battery. For standard terminals, attach ring terminal on shunt to post terminal on battery. For tab terminal batteries, attach shunt to battery terminal using 1/4" 20 stud and wing nut. For side terminal batteries, remove post terminal from shunt and thread into side terminal on battery. Attach battery cable to shunt using 3/8" 16 nut from post terminal. The Digital Multimeter will withstand DC input of Amps for up to 30 seconds. To avoid blowing fuse in meter, use the DC shunt when checking current draw of 12 volt starter motors or DC output on 16 Amp regulated alternator. Charging output can be checked with the engine running. All connections must be clean and tight for correct amperage readings. 1. Install shunt on negative battery terminal.

BRIGGS & STRATTON ENGINE REPLACING ENGINE OF ANOTHER MANUFACTURER
When replacing the engine of another manufacturer with a Briggs & Stratton engine, the equipment requirements must be known so that the replacement alternator system has the same output as the original system provided. Often the equipment wiring harness is not compatible with the Briggs & Stratton alternator output harness. To create a compatible system it may be necessary to modify the equipment wiring harness. To do this, a wiring diagram for the equipment is essential. The original keyswitch may also create a problem. Even though the keyswitch harness connectors appear to be identical, there are internal differences to keyswitches. Therefore it is necessary to have a diagram of the keyswitch showing the terminal positions and their functions. For example, see the 5 terminal switch diagrams in Figure 1 and Figure 2. The keyswitch in Figure 1 is compatible with all Briggs & Stratton alternators. Note in Figure 2, that when the brand X keyswitch is in the START position there is no battery voltage available to the #2 switch terminal. Consequently, if the replacement Briggs & Stratton engine was equipped with a carburetor solenoid, it would not function. This is why it is important to have a diagram of the keyswitch when replacing engines, or replace the keyswitch with one that is compatible with all Briggs & Stratton alternator systems. NOTE: The 5 terminal Briggs & Stratton keyswitch, part number 490066, shown in Fig. 1 has been replaced by a 6 terminal keyswitch, part number 692318. The additional terminal provides a direct connection for the charging lead at the keyswitch.

PERFORMANCE CONTROL ELECTRONIC GOVERNOR
Some Vanguard V-Twin engines are equipped with the Performance Control electronic governor control system for generator or welder applications. The electronic governor provides more responsive governing than a mechanical governor system. Engines equipped with the Performance Control electronic governor control system have no mechanical governor components. The Performance Control electronic governor control system cannot be retrofitted to mechanical governor engines. The Performance Control electronic governor control system consists of an electronic control module, wiring and stop switch harness and a throttle actuator. The control module is equipped with an idle down circuit for applications requiring that feature. By cutting the yellow wire loop, the control module may be converted to 50 cycle 3000 RPM generator applications. The engine must be turned off when cutting Yellow Cycle loop, then start the engine for the system to reset the engines RPM for 50Hz cycle.

AWG Wire Sizes (see table on the next page)
AWG: In the American Wire Gauge (AWG), diameters can be calculated by applying the formula D(AWG)=.00592((36-AWG)/39) inch. For the 00, 000, 0000 etc. gauges you use -1, -2, -3, which makes more sense mathematically than double nought. This means that in American wire gage every 6 gauge decrease gives a doubling of the wire diameter, and every 3 gauge decrease doubles the wire cross sectional area. Similar to dB in signal and power levels. An approximate form of this formula contributed by Mario Rodriguez is D =.460 * (57/64)(awg +3) or D =.460 * (0.890625)(awg +3).

Metric Wire Gauges (see table on the next page)
Metric Gauge: In the Metric Gauge scale, the gauge is 10 times the diameter in millimeters, so a 50 gauge metric wire would be 5 mm in diameter. Note that in AWG the diameter goes up as the gauge goes down, but for metric gauges it is the opposite. Probably because of this confusion, most of the time metric sized wire is specified in millimeters rather than metric gauges.
Load Carrying Capacities (see table on the next page)
The following chart is a guideline of ampacity or copper wire current carrying capacity following the Handbook of Electronic Tables and Formulas for American Wire Gauge. As you might guess, the rated ampacities are just a rule of thumb. In careful engineering the voltage drop, insulation temperature limit, thickness, thermal conductivity, and air convection and temperature should all be taken into account. The Maximum Amps for Power Transmission uses the 700 circular mils per amp rule, which is very conservative. The Maximum Amps for Chassis Wiring is also a conservative rating, but is meant for wiring in air, and not in a bundle. For short lengths of wire, such as is used in battery packs you should trade off the resistance and load with size, weight, and flexibility. NOTE: For installations that need to conform to the National Electrical Code, you must use their guidelines. Contact your local electrician to find out what is legal!
