Catching the electron flow: Multimeters and fuse box diagnostics
from Underhood Service
Taking the car apart with a screwdriver in one hand and a flashlight in the other isn’t always the best diagnostic technique for diagnosing routine problems like parasitic battery drains, worn ignition switches, bad grounds, bad ignition modules and bad relays. In contrast, keeping the diagnostic process simple by using a professional multimeter to diagnose circuit defects in modern electrical systems through the underhood and interior fuse boxes is like putting money in the bank. In short, the multimeter is the first tool — and perhaps the last tool — to reach for in a diagnostic tool box when diagnosing electrical system problems.
