bolens g16 xl tecumseh engine

hello i have a bolens g 16 xl with a 16 horse overhead valve engine and it has the electric clutch i bought a new battery for this tractor and it was fine for about 2 weeks now after a few hours of use or a few starts the battery is dead and has to be charged and it will stay charged until a few starts or you use the tractor for a few hours so i assume the tractot is not charging is the alternator built in with the starter on this or where is it or is it possibly a voltage regulator any help would be appreciated thanks and god bless

OHV16 Charging System

These engines had either a 10amp or 20amp charging system.
Now, I'm "assuming" this is an older Bolens tractor with the
Tecumseh OH160 cast-iron engine in it ?? If equipped with an
elec PTO clutch, you'd more than likely have the 20amp system.
You've obviously got a charging problem. If the battery goes
dead 'til you recharge it, the elec clutch is running off the battery
and drawing it down. It usually only takes an hour or so of doing
this to KILL the charge in a battery. Post some engine #'s
so we'll know what we're dealing with here. THANKS !!

Hello richy!

The #s and make of the engine could help, but check (just in case) the wires coming out from under the top of the engine to be sure they are plugged into the wiring harness.

OH160 Charging System

Richard,

From under the flywheel the alternator wires will be 2 "YELLOWS"
which are the A/C's from alternator, and 1 "GREEN". This will
plug up into the regulator/rectifier. Yellows take A/C in, and a
"RED" lead brings D/C out for keeping the battery charged and
powering the elec clutch. A GREEN & RED wire double plug is
the result of what COMES OUT of the reg/rectifier. The "RED"
is the charging wire and the "GREEN" is the cut-off wire to the
ignition switch. With the engine running, take a voltmeter,
unplug the 3-wire plug where it plugs into the reg/rectifier, and
put the red lead in one side of the plug, the black lead in the
other yellow wire side. With engine running, you should read
32 volts @ 2500RPM, 38 volts @ 3000RPM, & 45 volts @ 3600RPM.
If you read these values....ALTERNATOR IS OK. The culprit would
probably have to be the regulator/rectifier. You CANNOT DO
a D/C check on this system. If your battery is KNOWN TO BE
GOOD....then the reg/rectifier IS bad.
