not provided, the manifold and/or a pipe coupling may
be drilled and tapped. After measurement is made,
plug the hole with an ordinary pipe plug.

BATTERY CONNECTION
Connect the-positive battery cable to the start solenoid
(located in the control box). See Figures. Connect
the negative battery cable to a good ground on the
generator.
Do not disconnect the starting bat-
terfes while the engine is running.
The resulting overvoltage will damage the electric
choke and other control components.
In mobile applications where the generator is normally
operated in ambient temperatures above 0°F and the
battery is kept charged by frequent tunning of the
unit, a single 12 volt battery of 72amp/hr capacity
minimum is sufficient.
WIRING
All wiring must meet applicable local electrical codes.
Wires must be of adequate size, properly insulated
and supported in an approved manner. Have a qualified
electrician install and inspect the wiring.
Mount switches and controls securely to prevent damage
from vibration and road shocks. All switches should
be vibration proof to prevent accidental opening or
closing while the vehicle is in motion. Protect load
circuits and generator output circuits by proper size
fuses or circuit breakers to prevent severe overload
conditions from damaging the generator.
Some special precautions must be taken when installing
AC load wires to Onan electric plants if the plant is
single phase but has 3 output wires (120/240 volt
output). Balance the 120 volt loads between the two
legs of the generator windings. This means connecting
half of the vehicle's 120volt load to each leg of (he
generator output. The average running load would be
approximately equal for each side of the generator
output. Attempting to take the full load off only one
leg couto damage the generator output windings.
Connect any 240 volt load across both windings.
