Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Digital Multimeter
1998 Saturn SL2 L4-1.9L DOHC VIN 7SECTION Digital Multimeter
Digital Multimeter:
Digital multimeters approved for use on Saturn vehicles must have an input impedance of ten megohms (10,000,000 ohms). Input impedance is listed in the multimeter's owner guide.
IMPORTANT: The input impedance of a multimeter stands for the resistance between the red and black leads, only when you are measuring voltage. When measuring resistance, the only resistance other than in the circuit being measured is in the actual leads being used.
A digital multimeter performs all the tests that a test light can perform, with a greater degree of accuracy. In addition, a multimeter can be used to test for current flow in a circuit.
IMPORTANT: Always follow the manufacturers recommendation when checking for current. All multimeters have a maximum current rating, do not exceed this rating. Not all multimeters contain a fuse that protects the multimeter from damage if a larger current draw is experienced. So be careful when checking for current draw.
