Diagnosing a Short Circuit
1.
A short can be the result of two faulty
components: faulty solenoid manifold or
faulty control board.
2.
Unplug all solenoid manifold wires
connected to control board outputs ‘1’,
‘2’, and ‘C’, see
3.
Navigate to Diagnostics Screen #2 on
control display, see
4.
Actuate outputs ‘1’, ‘2’, and ‘C’, see the
5.
If the control board is still registering a
short, the board is bad and needs to be
replaced. If the control board is now
registering an open, the solenoid
manifold is bad and needs to be
replaced.
Diagnosing an Open Circuit
1.
An open can be the result of two faulty
components: faulty solenoid manifold, or
faulty control board.
2.
Unplug all solenoid manifold wires
connected to control board outputs ‘1’,
‘2’, and ‘C’, see
3.
Navigate to Diagnostic Screen #2 on
control display, see
4.
Actuate outputs ‘1’, ‘2’, and ‘C’, see the
5.
Measure the DC voltage across the
three solenoid outputs:
6.
If control board voltages are in this
range, the control board is good. The
solenoid manifold needs to be replaced.
7.
In the Diagnostics Screen #3, check the
amperage of the three solenoid outputs
using he diagnostics screen, see
8.
If any of the outputs are reading lower
than shown in the table, there is an open
in the solenoid manifold and it must be
replaced.
