Taking Care of the Unexpected 173
If Your Battery Is Low (or Dead)
If an overvoltage, overcurrent, or short circuit is
applied, the battery fuse may blow.
Do not jump-start as this can damage your CRF’s
electrical system and battery.
Bump starting is not recommended.
Check the battery voltage using a digital multi
meter with the cable connected.
Below 1V: The battery has failed; replace the
battery.
Between 1V and 8V: The battery may have
failed; charge the battery using a li-ion battery
charger and then recheck, see page 137 Battery
Charging. If you can't charge the battery or it
appears unable to hold a charge, see your
dealer.
