5-4 Testing Electrical Resistances (120 cc) NOTE: The following test procedure starts by SPARK PLUG CAP 1. Remove the spark plug cap from the high ten- sion lead by rotating it counterclockwise. 2. Set the selector in the OHMS position. 3. Connect one tester lead to one end of the cap and the other tester lead to other end of the cap. B170 4. Spark plug cap resistance must be between 4000-6000 ohms. LIGHTING COIL 1. Disconnect the two yellow wires from the main wiring harness. 2. Set the selector to the OHMS position. 3. Connect the tester leads to the two yellow leads on the engine-side connectors. 4. Lighting coil resistance must be between 0.46- 0.68 ohm. Testing Ignition Key Switch 1. Disconnect the ignition key switch connectors; then connect the ohmmeter leads to each of the ignition key switch terminals. 2. With the switch in the OFF position, the meter must read less than 1 ohm of resistance. 3. With the switch in the ON position, the meter must read OL (infinite resistance). Testing Electric Fuel Pump (660 cc) 1. Remove the hardware securing the console to the gas tank and frame; then move the console out of the way. 2. Disconnect the fuel pump (white two-wire con- nector) from the main wiring harness. 3. Connect the positive lead of a 12-volt power supply to the red wire and the negative lead of the 12-volt power supply to the black wire. 4. The pump should operate (it would be heard running). NOTE: If the fuel pump fails to operate, the pump Testing Electric Fuel Pump (1100 cc Z1) 1. Open the hood; then locate the fuel pump/level sensor four-wire connector and unplug the con- nector.
