How To Check Voltage Draw On Car Battery. A basic device is all youd need for a parasitic draw test with a multimeter. Just make sure it can test amperage has an auto ranging mode and is at least a.
Start to unplug the wires or fuses around your bike and see if the current reading goes to zero. Touch the black lead to the negative battery terminal. Set the dial to 20 which will allow you to accurately measure between 0-20 Volts.
If there is even the lightest voltage registered there is a leak.
Theyre a great tool to have especially if you like working on cars. Then we take the equivalent amp hours of a battery based in its RC or CCA rating see my article link above and divide it by parasitic amps 24 hours. Power Volts x Amps 42Watts or 12Volts x 035Amps. Put an Ohm-meter across the positive and negative cable.
