Troubleshooting the Water Boy
The LED will not change from green and no stages are activating despite
the EGT reaching the setting for stage 1
The electronics box is not receiving the EGT signal. Make sure the pyrometer
wires are securely attached to the electronics board and that they are in the
proper ports. If the problem persists, double-check the wire connections that go
to the electronics board.
The LED goes through all stages, but it is not injecting water
Make sure the tank is mounted above the pump to help eliminate air-locking of
the system. Check to make sure the pump is properly grounded and that the
wiring is correct. Check the fuse that is inline with the relay's yellow wire. Check
the filter housing to see if it is clogged. If so, remove element, rinse until clean
and replace.
The system goes to stage 1, but will not go to stage 2 or 3
Stages 2 and 3 are boost dependent. The electronics box must see
approximately 10 psi and the set EGT level to activate stage 2, and
approximately 15 psi and the set EGT level to activate stage 3. If your vehicle is
meeting both boost and EGT requirements and still not activating, check to make
sure both ends of the boost line are securely attached and that the line is not
kinked.
The LED won't come on when the power is turned on
Check the black wire coming from the LED, is it properly grounded? Check the
fuse that is in line with the electronic box's red wire. Check the fluid level in the
tank as this can be an indication it is empty.
