Testing Voltage on Voltage Transformer for RECARO seat
• Detach plug connection from the battery cable to the
voltage transformer.
• Measure the voltage existing at the contacts of the feeder
cable (see drawing).
It must amount to at least 19 volts.
• Reconnect the plugs.
• Detach the plug connection to the RECARO seat.
• Measure the output voltage.
Depending on the charging status of the batteries, it must
amount to between 2.5 and 4 volts.

NOTE:
The voltage transformer provides an output voltage of 12 volts only under load
(seat connected and switched on). In conditions without load, only a level of
between 2.5 and 4 volts is to be measured.
CAUTION:
Malfunction
No voltage at the
feeder cable?
Voltage below 19 V?
Output voltage
higher than 4 volts and
lower than 2.5 volts?
90
Avoid by all means bridging the contacts of the power supply.
