ESSENTIAL ELECTRICAL CONCEPTS
NOTE:
Make sure that resistance values are expressed in the same units when comparing
measured resistance values to diagnostic specifications.
Resistance should match the specifications in the service information.
•
If resistance is too high, check for an open circuit or a faulty component.
•
If resistance is too low, check for a short circuit or faulty component.
Converting Resistance Values:
To convert ohms to kilo - ohms (and vice versa) just move the decimal point three places. To
convert ohms to megohms (and vice versa) just move the decimal point six places.
Converting resistance values
−
Automotive system resistance values vary from large to
small.
Low resistance levels are expressed in ohms. Large resistance values are expressed in
kilo
−
ohms and very large values are expressed in Mega-ohms.
•
1 kilo
−
ohm = 1,000 ohms (1.0 kW)
•
1 Mega-ohm = 1,000,000 ohms (1.0 MW)
Convert ohm readings as follows:
•
Kilo
−
ohms to ohms
−
decimal point moves 3 places to the right.
•
Ohms to kilo
−
ohms
−
decimal point moves 3 places to the left.
