NOTE: Be cautious when troubleshooting with a test
light or voltage meter. You may get a false indication
as shown below. [Figure 27-1] It will indicate that a
wire connection exists – but it may not necessarily
enough.
We strongly recommend that you examine both
voltage and current, or isolate sections of the lift
wiring using the process of elimination with a known
good/fully charged 12V automotive battery or known
good/fully charged power chair/scooter battery.
