17-18 ELECTRICAL SYSTEM Precautions ○ Electrical Connecto rs: Female Connectors [A] Male Connectors [B].
ELECTRICAL SYSTEM 17-19 Electrical Wiring Wiring Insp ection • Visual ly inspect the wir ing for signs of burni ng, fraying, etc. If any wiring i s defective, replace the damaged wiri ng. • Pull each connector [A] apart and inspect for corrosion, dirt, and damage.
17-20 ELECTRICAL SYSTEM Battery Battery Removal • T urn off t he ignition switch. • Remove: Seat (see Frame chapter) Battery Holder Bolts [A] and Collars Battery Holder [B] • Disconnect the battery negative (–) cabl e [C] first, and then the positi ve (+) cable [D].
ELECTRICAL SYSTEM 17-21 Battery CAUTION Do not remove the aluminum sealing sheet [A] from the filler ports [B] until just prior to use. Be sure to use the dedicated electrolyte contai ner for correc t electrolyte volume. • Place the battery on a level surface.
17-22 ELECTRICAL SYSTEM Battery • Gently remove t he container f rom the batter y . • Let the battery sit for 60 minutes prior to charging to al low the electrol yte to permeate int o the plates for opti mum performance. NOT E ○ Charging the batter y immediately after filli ng can shorten service lif e.
ELECTRICAL SYSTEM 17-23 Battery If an engine will not st art, a horn sounds weak, or lamps are dim, it indicates the b attery has been discharged. Give refres h charge for 5 to 10 hours with c harge current shown in the speci ficati on (see Refreshing Charge).
17-24 ELECTRICAL SYSTEM Battery Chargi ng Condit ion Inspecti on Battery charging condi tion can be checked by measur ing battery te rminal voltage. • Remove the battery ( see Battery Removal) . CAUTION Be sure to disconnect the negative ( − ) lead fi rst.
