Power Supply (+54 Circuit)
FAULT DIAGNOSIS HINTS1. Check the battery voltage.
2. Check the connections on distribution block 75 and the +30(230) and +54(231) terminal blocks.
3. If current is present on the +30 terminal but not on the +54 terminal, check that ignition switch relay 21 is working by turning the ignition switch to the Drive position. Current should then be present on relay connection 87.
4. Check the relevant wiring harness.
