It works by using 2 probes to send a current through the circuit and measuring how much resistance, in ohms, that current encounters. The first step in using an ohmmeter is setting it up. Once you''ve done that, you can use it to measure the resistance of any circuit simply by holding the probes on opposite sides of it.
In order to accurately detect the parasitic draw, you need to begin with a fully-charged battery. Pop the hood and locate your vehicle''s battery. Use a vehicle battery charger to charge the battery to 100%. Many car batteries are 12.6 volts. You can check the power with a multimeter to ensure the battery is fully charged.
THIS IS the real deal. If you make that the ammeter will barelly get load through it. No load, no heat. No heat, no damage, everywhere, not just on ammeter. The car load demand will be allways the same ( average ) at main splice with a poor alt or a good alt. Having a good alt just will need to keep good conections to feed the main splice into ...
With the engine off, battery voltage should be between 12.5 and 12.8 volts. If it''s below that, charge the battery with a battery charger before you conduct the test again. Then start the engine and check for increased voltage readings. If you see higher readings, chances are the alternator is good.
