3.4 Changing the spark plugs and checking the spark plug gap:

 

1)

Remove the wire on the spark plug and use a

13/16” socket to remove the spark plug.

2)

Check the gap on the spark plug to verify that

it is 0.03 in using a feeler gauge.

3)

If the spark plug is worn, overheated, wet or

carbon fouled replace the spark plug.

4)

Install the plug into cylinder head and torque to

16 ft.-lbs. Be careful not to overtighten the

spark plug.

SECTION 4: ELECTRICAL SYSTEM

This mower is equipped with three protective fuses:

•

25 amp main fuse (pictured to the right).

•

15 amp linear actuator fuse (deck lift)

•

10 amp clutch fuse (blade engagement)

The 25 amp main fuse is located on the left side of the 

unit, by the starter solenoid.  The 15 amp actuator and 

10 amp clutch fuses are located just underneath the 

control panel.  You will need to remove the four screws 

that hold the control panel to the tank using a 3mm or 

1/8" hex wrench.

A blown fuse usually indicates a problem within the 

electrical system or an electrical component,  Ensure 

the battery terminals are tightly fastened. Never 

replace a fuse with one of a higher amperage rating or 

"bypass" a fuse in anyway.  Doing so creates a 

significant fire hazard and can cause severe damage 

to the mower's electrical components.  If a fuse is 

repeatedly blowing, contact your Bad Boy Dealer.

on most models, the red wire coming out of the engine 

is the charging wire from the alternator. Check for 

13.6-14-2 volts dc at this wire with engine at full 

throttle.

If you are having issues starting your mower ensure 

the signal wire is connected to your starter solenoid

Check the condition and connection of the relays 
located under the control panel. Ensure that they are 
clean and connected. Make sure that wire terminal 
ends have not been pushed out of the relay block.

 

The linear actuator is the mechanism that raises and 
lowers the deck. If it ever starts to make noise when 
raising and lowering the deck you might find it 
necessary to tighten the nuts and bolts on the front and 
rear of the actuator. Be careful not to overtighten these 
as you can damage the actuator. Also if your actuator 
ever stops working make sure to check the fuse under 
the control panel as shown on the previous page.
