Electrical system

BATTERY EFFICIENCY CHECK • Remove the seats as described in chapter C “Bodywork”. • Turn the ignition switch to the “OFF” position. • Disconnect the cable from the negative (-) pole of the battery. • Connect the multi-tester between the negative (-) terminal and the negative (-) cable of the battery. Battery current loss check

Losses are indicated if the tester measures more than 2÷2.5mA. Battery current loss: less than 1mA.

E First of all when using an ampmeter, utilise a high range of the multi-tester because the current losses in the case of malfunctioning could be elevated Do not turn the ignition switch to the ON position while measuring the current. If losses are found, search for the part where the tester measures less than 2÷2.5mA by removing couplings and connectors one at a time.

Remove the seat as described in chapter C “Bodywork”. • Start the engine and let it idle. • Make sure that between one of the two red ignition relay wires and the engine earth the voltage is greater than 14 V. Charge feed check
