B), and less than 0.05 VDC between the Equalizer' s GND terminal and the battery ground terminal
(Battery A negative terminal that is connected to chassis ground). In most installations, the Battery
Equalizer' s terminals are wired directly to the battery terminals to prevent voltage loss that could occur in
switch contacts, connections, and long wire runs. Since the equalizer can be operated in temperatures up
to 71º or 75º C, use wire rated at least 90º C. See Wire and Fuse Size Chart.

must be tested differently. The following three test procedures apply
only
to the equalizer family listed.
CAUTION
Servicing of electrical systems should only be performed by trained and qualified technical personnel.
Equipment Required
VoltMeter having 0.01 volt resolution. (Fluke Model 87 Multimeter recommended).
Clamp-on amp meter (Fluke Model 36 Clamp-on Meter recommended).
