Servicing The Fuses; Jump-Starting The Machine - Toro 74906 Operator's Manual

Servicing the Fuses

The electrical system is protected by fuses. It requires no
maintenance, however, if a fuse blows check the component
and circuit for a malfunction or short.
The fuses are located on the right console next to the seat
(Figure 61).
1. To replace the fuses, pull out the fuse to remove it.
2. Install a new fuse (Figure

Jump-Starting the Machine

1. Check and clean corrosion from the battery terminals
before jump-starting. Ensure that the connections are
tight.
CAUTION
Corrosion or loose connections can cause
unwanted electrical voltage spikes at any time
during the jump-starting procedure.
Do not attempt to jump-start with loose or
corroded battery terminals, or damage to the
engine or EFI may occur.
DANGER
Jump-starting a weak battery that is cracked
or frozen, or has a low electrolyte level or
an open/shorted battery cell can cause an
explosion resulting in serious personal injury.
Do not jump-start a weak battery if these
conditions exist.

2. Make sure that the booster battery is a good and fully
charged lead-acid battery at 12.6 volts or greater.
Note: Use properly sized jumper cables with short
lengths to reduce voltage drop between systems. Make
sure that the cables are color coded or labeled for the
correct polarity.
CAUTION
Connecting the jumper cables incorrectly
(wrong polarity) can immediately damage the
EFI system.
Be certain of battery terminal polarity and
jumper cable polarity when hooking up
batteries.
WARNING
Batteries contain acid and produce explosive
gases.
• Shield the eyes and face from the batteries
at all times.
• Do not lean over the batteries.
Note: Ensure that the vent caps are tight and level.
Place a damp cloth, if available, over any vent caps on
both batteries. Also ensure that the vehicles do not
touch and that both electrical systems are off and at the
same rated system voltage. These instructions are for
negative ground systems only.
3. Connect the positive (+) cable to the positive (+)
terminal of the discharged battery that is wired to the
starter or solenoid as shown in
