A8: Check Relay Coil Circuit Continuity

With EM013 disconnected, measure the resistance between EM013/001 & relay socket pin 1

Is the resistance < 0.5 OHM?

Yes
Go to A9

No
Inspect connectors EM013, EM002/009, RH001/11, BT002/006 & BT011/010 for corrosion, damage, bent or pushed back pins & repair as required. Test the system for normal operation
