Toro Starting System Guide - English

Starting System Test This is an excellent test to use when a “slow crank/no start ” problem is encountered. It will tell you if the problem is due to an electrical open, short or high resistance in the starter circuit. NOTE: The battery condition and the state of charge must be checked before testing the starter system. Tool(s) required: Digital Multimeter and Inductive Ammeter (AC/DC Current Transducer).

Test instructions: Properly connect the inductive Ammeter to the multimeter ( refer to the manufacturers instructions). Set multimeter on Volts scale. With the key off place the inductive ammeter around the main negative (-) battery cable and read the meter prior to activating the starter system. Adjust the meter to read zero ( if applicable). Crank the engine for at least 3 seconds and record the results. Battery Test Use a Digital multimeter to measure the voltage between the battery terminals. Set the multimeter to the DC volt setting. The battery should be at a temperature of 60° to 100° F (19° to 38° C). The ignition key should be off and all accessories turned off. Connect the positive (+) multimeter lead to the positive battery post and the negative (-) multimeter lead to the negative battery post. NOTE: this test provided a relative condition of the battery. Load testing of the battery will provide more accurate information.

Tool required: Digital Multimeter DC volts setting. Test instructions: Connect the positive (+) test lead to the power (or most positive) side of the component, circuit or connection. Connect the negative (-) test lead to the ground (of least positive) side of the component, circuit of connection. Turn on the circuit to be tested and read the voltage. Remember – when performing voltage drop tests the circuit must be complete and activated to locate the resistance.
