You can also use a multimeter to test thealternator. In addition to acquiring a multimeter, a mobile charger, jumper cables, and cleaning gear for the battery, you may consider a portable jump box. Approximately$40-$100, a portable jump box bypasses the need for a secondary vehicle when ju...
A digital multimeter (DMM) is one of the most useful test instruments in any automotive electrician's tool kit. Every DMM is slightly different but there are some general guidelines you can follow for its use. An old analog voltmeter will work too but be careful of polarity when using one...
2: Matching leads to cables As a rule of thumb, you must turn off ignition and headlights before testing the battery. Once it’s done get your equipment ready. Touch black lead in multimeter to negative and red to positive battery cable. When it’s matched wrongly, you would see an awkw...
