HITACHI Regulator: Testing: Relay: I-Mark
- Connect voltmeter between negative terminal and ground. Increase engine speed gradually. Voltmeter reading should be 4.0-5.8 volts when indicator light goes out. If cut-in voltage is too high, bend coil arm "A" down. Bend up if voltage is too low. See Fig 1.

- If adjustment of core arm does not correct cut-in voltage, proceed with point gap adjustment. Disconnect battery. Check armature core gap with armature depressed until moving point is in contact with "B" side point.
- Adjust core gap to 0.012" (0.30 mm) by bending point arm "B". Release armature and adjust gap between "B" side point and moving point to 0.016 - 0.047" (0.40 - 1.2 mm) by bending point arm "C". After point adjustment, recheck cut-in voltage. If not within 4.0-5.8 volts, repeat cut-in voltage adjustment.
