Battery Testing - Briggs & Stratton 110000 Service, Troubleshooting, And Repair Manual

5. Activate starter motor and note readings of
meter and tachometer.Take reading after
meter stabilizes (approximately 2-3
seconds).
With a fully-charged battery, the starter motor
should deliver 6500 RPM (minimum) and 35
Amps (maximum). If the starter motor does not
meet these specifications, it must be replaced.

Battery Testing

A 12 Volt, lead acid, wet cell battery is required
to operate the starter motor. This type is
available as a wet charge or dry charge battery.
The wet charged maintenance-free battery is
filled with electrolyte and sealed at the time
production. The level of electrolyte cannot be
checked.
The dry charge battery requires electrolyte to be
added at the time the battery is placed in service.
Before activating a dry charge battery, read and
follow the manufacturer's recommended
procedure.
WARNING
Storage batteries give off explosive hydro-
gen gas during recharging.
Slightest spark will ignite hydrogen and
cause explosion.
Battery electrolyte fluid contains acid and
is extremely caustic.
Contact with battery contents will cause
severe chemical burns.
A battery presents a risk of electrical shock
and high short circuit current.
• DO NOT dispose of a battery in a fire.
• DO NOT allow any open flame, spark, heat, or
lit cigarette during and for several minutes after
charging a battery.
• DO NOT open or mutilate the battery.
• Wear protective goggles, rubber apron, and
rubber gloves.
• Remove watches, rings, or other metal objects.
• Use tools with insulated handles.
Check Battery and Cable Sizes
The following battery size recommendations are
based on the minimum temperature expected
and the correct weight of oil being used.
• 30 Amp. Hr. +20ºF (-6ºC) or higher
• 40 Amp. Hr. -5ºF (-20ºC) or higher
• 50 Amp. Hr. -15ºF (-26ºC) or higher
The following cable sizes are based on the total
distance from the battery positive (+) post to the
starter switch and/or solenoid, plus the ground
return to the battery negative (-) post.
• #6 AWG - 4 ft. (1.2m) or less
• #5 AWG - 5 ft. (1.5m) or less
• #4 AWG - 6 ft. (1.8m) or less
WARNING
Battery posts, terminals, and related
accessories contain lead and lead
compounds - chemicals known to the State
of California to cause cancer and
reproductive harm. Wash hands after
handling.
Check Battery Installation
1. Ensure the battery is in a holder with a flat
base. Tighten holder down evenly until
snug. DO NOT over tighten.
2. Clean, then lightly grease the terminals.
3. Connect positive (+) cable to positive
battery post FIRST, to prevent sparks from
accidental grounding. Tighten connector
securely.
4. Connect negative (-) cable to negative
battery post. Tighten connector securely.
