I. LF481Q3 engine 1. If the engine fails to run or runs slowly at start, carry out the trouble diagnosis and removal as per Table 1-51. Table 1-51 67 S/N Operation Test Results Actions 1 Measure the voltage between the two terminals of the battery with a multimeter. Is the voltage about 10-12.5V? Yes Next step No Repair or replace battery 2 Turn the ignition switch to ON. Measure the voltage between the ignition switch and the terminal of the battery positive pole. Is the voltage about 10-12.5V? Yes Next step No Repair terminal or replace lead 3 Turn the ignition switch to START.
Measure the voltage of the terminal of the ignition switch to connect with the positive pole of the start motor with a multimeter. Is the voltage greater than 8V? Yes Next step No Repair or replace ignition switch 4 Keep the ignition switch in START. Measure voltage of the terminal of the positive pole of the start motor with a multimeter. Is the voltage greater than 8V? Yes Next step No Repair terminal or replace lead 5 Check the start motor for open or short circuit with a multimeter. Yes Repair or replace start motor No Next step 6 Check if the engine is locked for lack of lubrication.
Yes Remove the trouble No Next step 7 In winter, check if the start motor is affected by high resistance as improper engine lubricant and gear box oil is applied. Yes Replace the oil No Repair or replace timing belt
