PCB harness test
Step by step guide
Our PCB test card devices are proving popular with installers. So make sure you’re making the most of yours, here’s our step by step guide on how to use it.
Please note! PCB test cards are only suitable for use with Greenstar Ri, Si, i junior and CDi boilers.
Step 1: Safely isolate the power to the appliance- make sure the boiler is switched off on the fascia and at the mains supply. Do not turn the power back on while using the test card.
Step 2: Remove the rear cover of the drop down fascia at the front of the boiler to gain access to the circuit board where appropriate.
Step 3: Remove the harness from the boiler circuit board, then attach it to the appropriate nodes on the PCB test card depending on the boiler model and ensure it is securely plugged in.
Step 4: Using a multimeter it is now possible to test the heating and hot water sensors, over heat stats, gas valve solenoids and diverter valve resistances.
Please note that the PCB test cards are only available on attendance of a gas boiler training course or during special promotions.
