RESISTORS - MAINTENANCE PRACTICES
1.
General
A. This
section provides a
chart for determining
the value of resistors,
and shows some typical
part
numbers and
how to determine the value
from the part number.
B. When
a resistor burns out, the
cause frequently will
be a malfunction in some
other part of the
circuit.
Check for shorted wires
or other malfunction that could cause
excessive current.
C. Color codes for resistors. Refer to Figure 201.
D. Part
number value
guide.
(1) CM3527 is 0.5 watt. CM3526 is
1 watt. These are Cessna engineering
standards which are
followed by a dash number for the complete part number.
(a) The first number after the dash is the first digit.
(b) The second number after the dash is the second digit.
(c) The third number after the dash is the number of zeros.
(d) The fourth letter is the tolerance:
G = plus or minus 5 percent S
= plus or minus 10 percent.
EXAMPLE:
CM3527-430G
is 43 ohms, one-half
watt, plus or
minus 5 percent.
(e) For values less than 10 ohms, R is used in place of the second number and represents a
decimal for the value.
Example:
CM3527- 2R7G is 2.7 ohms,
one-half watt, plus or minus 5
percent.
