VOLTMETER READING
(No Load)
HYDROMETER READING
100% 12.7 v or over 1.27
75% 12.5 v 1.23
50% 12.4 v 1.20
25% 12.2 v 1.17
Discharged 12.0 v 1.10
ℹ️ Voltage readings should be taken at least 4 hours (and could be up to 12 hours depending
upon charging rates) after recharging to obtain an accurate reading.
The above figures are for the battery when under no load, if a battery is on the point of
failing or not fully charged then the only test that will determine this is to take the
readings under load (drop test). This can be achieved by using the Powrtouch mover
with the rollers engaged to the tires and driving both rollers forwards or backwards, if
the reading drops to 12 volts or less the safety cut out on the ECB will stop the
Powrtouch to prevent damage to the battery. However, this is an indication of
insufficient battery voltage to drive the Powrtouch caused by an under charged or
failing battery.
PLEASE BEAR SAFETY IN MIND AND THAT BEING IN THE RV WATCHING THE METER
YOU DO NOT DAMAGE THE RV BY RUNNING INTO AN OBSTRUCTION.
The above voltages are accurate at 25
O
Celsius (77
O
F). In temperatures less than this the
battery performance and output decreases by 1.25% per degree.
5.5 FAULT FINDING CHART
Symptom of Fault Possible Fault and Method of Correction
Unit fails to operate Reset the ECB by turning off the isolation switch and removing
the key for at least 20 seconds and then turning on again. The
green light on the ECB should be illuminated.
Unit fails to operate
–
seems completely dead
–
Red Light flashing on ECB
Over heating - remove isolation key and leave 20 minutes to
see if the thermal fuse will reset itself, RED LIGHT WILL STOP
FLASHING and the ECB should not feel hot.
Unit fails to operate
–
seems completely dead
Check that the green light is illuminated on the electronics, if
not check that the in-line fuse is not broken and 12volts DC is
getting to the ECB.
Unit fails to operate or
operates intermittently Check the battery voltage of the handset is correct at 9.5 volts.
If the 2 rows of Red LED’s flash, then this is a sign the handset
battery is low
Unit fails to engage on one
side (auto mover only) Ensure that both sides have fully disengaged before turning off
the mover. Using the supplied T bar wind clockwise by 2 turns.
The mover should then auto engage again when using the
remote control.
ALWAYS ENSURE THE MOVER HAS FULLY PARKED AND
LIGHTS ON HANDSET HAVE STOPPED FLASHING
BEFORE TURNING OFF YOUR ISOLATOR SWITCH
Unit fails to operate or
moves intermittently Badly connected or corroded battery terminals, check battery
terminals are clean and connected as required.
