Information:
Test
Set up as illustrated and turn the alternator to measure vacuum pump performance. If the measurement is lower than nominal values, disassemble and check for broken vane, traces of interference on housing, rotor and plate surfaces. Replace if defective.Ultimate vacuum Exhaust characteristics after 20 seconds 4.9 Safety Relay
(1) R8T30171 Safety Relay Inspection Measure voltage at each terminal in the sequence shown below to identify faulty parts.(a) On-vehicle Test (b) Component TestThe resistance value between terminals "R" and "L" shall be within specified range.(2) Inspection by RX-Q30 Safety Relay Continuity Tester Check between terminals marked with * applying 15 to 17 V between "K" and "E" terminals.4.10 Preheater
Intake air heater
(1) Removal and installation (Refer to Group 15 Intake and Exhaust.)(2) Inspection Perform the following inspection and check the function of each part or the wiring if necessary.(a) Time required before indicator becomes red-hot: Standard timeNominal value 40 to 60 seconds (ME037260, ME037197:1.83 kW)20 to 30 seconds (ME077014, ME077015:2.86 kW)(b) Check each terminal of the air heater for looseness and the heater element for damage and contact with other parts.Heater relay
Inspection (1) Check to ensure that there is continuity between the terminals "B" and "S" when 2.3 A (24 V type) or 5.2 A (12 V type) exciting current is applied between terminal "SW" in the illustration and body ground.(2) Check also the heater relay fuse and replace if it has been burnt out. When replacing fuses, be sure to use a fuse of specified capacity.4.11 Automatic Stop Device
Energize-to-stop type
(1) Stop solenoid (a) Connect the stop lever and solenoid using the rod and remove the solenoid cover.(b) Push manually the stop lever to the stop position and adjust the rod so that the solenoid pointer gap becomes as specified.(c) Check that the stop lever to external stopper clearance is as specified when the stop lever is on the operation side.(d) In the state of (c) above, apply specified voltage to solenoid "B" terminal and check that the pointer gap and ammeter reading are as specified. (Stop lever stop side)(e) Tighten the lock nut of the rod.(f) Check that the solenoid pointer color has not changed and then install the cover.(2) Solenoid relay Make connections as shown above and perform the following checks.(a) Oil pressure timerSet the snap switch A to ON. Operate a stop watch as soon as the snap switch B is set to ON, and measure the time required before the solenoid is operated.(b) Stop timerSet the snap switch B to OFF 5 seconds after the solenoid has been operated. At the same time, using a stop watch, measure the time required before the solenoid is reset.The snap switch B is set to OFF 5 seconds after operation of the solenoid because if the solenoid is operated, it takes 5 seconds before the alternator voltage disappears.(c) Manual stop timerWhen the push switch C (stop switch) is set to ON, the solenoid is operated. Operate a stop watch as soon as the stop switch C is set to
