GENERATOR FUNDAMENTALS

Reroute stator lead 44 from the line side terminal of CB1 (renamed as CB1A in Figure 1-9) to the ground stud location previously occupied by stator lead Wire 33.

2.Move smaller gauge (#18 AWG) Wire labeled #44 (not shown), from the top of CB1A to the top of CB1. Renumber this Wire 11.

3.Reroute stator lead Wire 33, removed in step 1, to the line side terminal on CB1A.

4.Renumber ground Wire 33, located between the four-position terminal block and ground in Figure 1-8, as ground Wire 44, as shown in Figure 1-9.

5.Renumber Wire 44A from Figure 1-8 as Wire 33A in Figure 1-9.

6.Connect a 12 AWG jumper wire between line breakers CB1 and CB1A, as shown in Figure 1-9.

7.Remove the "tie bar" between the two-line breaker switch han- dles.

When connecting vehicle load leads, the following rules apply:

•Connect 120 VAC, single-phase, 60-Hertz, AC electrical loads, requiring up to the trip rating of cir- cuit breaker CB1, across AC output leads T1 (red) and T2 (white).

•Connect 120 VAC, single-phase, 60-Hertz, AC electrical loads, requiring up to the trip rating of cir- cuit breaker CB1A, across AC output leads T3 (black) and T2 (white).

•Try to keep the load balanced between the two cir- cuit breakers and the stator windings.

•The neutral line (T2, white) on all units is a ground- ed neutral.

Do NOT connect electrical loads in excess of any circuit breaker rating, or problems will develop with circuit breaker tripping, which causes a loss of AC output. Also, do NOT exceed the generator's rated wattage capacity. Add the watts or amps of all lighting, appliance, tool, and motor loads the generator will operate at one time. This total should be less than the unit's rated wattage/amperage capacity.
