Troubleshooting and Additional Help
Refer to the list below in the unlikely event that you have problems with your
MotorVac CarbonClean System.
Problem:
Solution:
1. Reverse Polarity LED is ON and the unit
is not operational.
Polarity is reversed on vehicle battery
connection. Check connections for correct
polarity.
2. Pressure Gauge on the unit displays
maximum pressure upon start up.
Output and Return hoses may be reversed. Press
the
Stop
button on the unit and check hoses for
correct connection.
3. Rapid loss of fuel from the unit reservoir.
Return hose connection may be incorrect,
allowing fuel/detergent to return to the vehicle's
fuel tank.
4. The unit will not power up.
Check that the
Power Leads
are connected
correctly. Verify 12.5 volts at battery.
5. START button is pressed but unit will not
build pressure.
With both hoses diconnected, close the
Pressure Regulator
clockwise, then open
¼ turn. Hold Start button down until pressure
builds. Verify that filter and fittings are snug,
use flashlite to look for small air bubbles in
lines near fittings. Look for good return flow
from top of reservoir.
6. The unit performs poorly.
Check all hoses and wires for cuts or frays.
Check cabinet for dents or impact markings.
Verify that the fuel filter has recently been
replaced. (Refer to the maintenance log in
Appendix A
for dates of services performed.)
