PART IDENTIFICATION CARDS
To help identify the resistors and diodes used in the construction of your car we have
mounted the resistors, capacitors, diodes, and an inductor onto cards. The card will
help you find the parts quickly. THE PARTS WILL NOT NECESSARILY BE LISTED IN
THE ORDER SHOWN IN THE PARTS LIST SECTION OR IN THE ASSEMBLY
PROCEDURE.
When you are ready to assemble the car kit, follow the procedure shown. For an
example refer to page 16. The first resistor called for is R13, 1k
Ω
resistor (brown-
black-red-gold). Locate it on the card ( ), verify that it is the correct value. Some
resistors may be mounted backwards on the card so you must be certain that you are
reading the resistors correctly. When the correct value has been established, only
then will you mount it into its correct position on the PC board.
IDENTIFYING CAPACITOR VALUES
Capacitors will be identified by their capacitance value in pF (picofarads) or
µ
F (microfarads). Most capacitors
will have their actual value printed on them. Some capacitors may have their value printed in the following
manner.

Note: The letter “R” may be used at times to
signify a decimal point; as in 3R3 = 3.3
