ELECTRICAL 1 FAULT DIAGNOSIS LUCAS CONSTANT ENERGY IGNITION SYSTEM - Preliminary Checks Inspect battery cables and connections to ensure they Inspect all L.T. connections, ensure they are clean Pick-up air gap Check air gap between pick-up limb and reluctor teeth NOTE: Air gap is set initially at factory and TEST 1: H.T. Sparking Remove coil/distributor H.T. lead from distributor TEST 2: L.T. Voltage Switch ignition ’On’ - engine stationary. (a) Connect voltmeter to points in circuit indicated (b) Compare voltages obtained with specified Expected readings V1 More than 12 volts. V2 1 volt maximum below volts at V1. V3 1 volt maximum below volts at V1. V4 0 volt - 0.1 volt. (c) If all readings are correct proceed to Test 3. (d) Check incorrect reading(s) with chart to identify (e) If coil and amplifier is suspected, disconnect L.T. (f) If engine will not start proceed to Test 3. |
