use a vomm set to infinite resistance if you have reistance one way and not the other way. diode is good (must be isolated from circuit) if no resistance both directions diode D.O.A.
the diode will have two polarities anode and cathode .take multimeter and set it in buzer mode or resistance mode and connect the positive terminal of multimeter to anode of diode and negative to the...
iif the car is running do an ac votage drop test from the positive on the alternator to the positive battery terminal. there should be less than 0.1v ac. if there is greater than 0.1v that would...
Normally, you'd know as fast as the electricity goes in. the grey band go to the output, remember !And if it fail, you can still use some Irons to heat the lead of the circuit.
The Diode Check setting on a DVOM is a special ohms setting that presents enough voltage to the tested device to conduct, if it were a diode. Old style VOM's did not have this problem, because they...
