QuestionQUESTION: I have a Craftsman 917.254241 lawn tractor just replaced a used Briggs & Stratton engine
281707 0179-01 88120831. Please help me how to hook up the wires. The Briggs & Stratton had two wires, one red wire on the oil stick side. the other wire is a thin black
wire connected to a screw at the throttle. The Craftsman had a red and black wires with the plug. Thanks
ANSWER: This link is pretty good for wiring a replacement engine:

The thin black wire connectee with a screw at the throttle is for the engine shut-off. This should run to the "M" on the key switch.
Are you replacing a Briggs engine with the Briggs engine?

QUESTION: Hi Eric,
Thank you for your info. I'm still couldn't figure out the single red wire from the(stator) Briggs engine. The original engine was Tecumseh
143 376012 SER 7292D. It had two wires green and red to black and red to
the equipment harness. Do I need any special harness to connect to the
equipment harness. Thank you again. Tim
ANSWER: You will have to splice the wires yourself as there is no "special" harness connector.

Page 42, on the link below, has the Tecumseh color codes:

Was the green wire connected to the black wire? According to the Tecumseh manual, the green wire is for the engine shut-off. To check this, use a multimeter on connecting the positive lead to the harness where the green wire connects. Connect the negative meter lead to engine ground, any metal part. With the key off, you should read zero ohms or continunity. When the key is in the run position you should have very high resistance, an open or no continunity.

Was the red wire connected to the red wire? Again, according to the Teccumseh manaul, this lead should be DC voltage for charging the battery.
Can you attach pictures of the old Tecumseh wires/connections, the Brigss wires/connections and the harness?

QUESTION: Hi Eric,
Sorry for the delay follow up question while trying to hook up the wires.
I wired the thin black wire(Briggs) to the equipment harness black wire which go to the "M". The red wire from (Briggs) stator to the equipment harness red wire.
The thing is that I can not start it from ignition key switch. The only
way to start the engine is from the portable battery cables clamped to
the starter and grounded to the engine black screw. Once it started I can turn it off from the key. Please help.
I'm already replaced the Solenoid and Ignition key switch.
AnswerLooking at the mower parts list, the starter solenoid has two large posts and two small terminals. The large posts are used to for battery cable connections. The two small terminals are ground and exciter.
When you turn the key switch to the start position, the "S" pin on the starter switch sends 12 volts DC to the exciter pin causing the solenoid plunger to connect the battery to the starter. Do you have 12 volts DC on the solenoid exciter post when the key is in the start position? Keep in mind all the safety switches must be working and in there correct position for the voltage to get to the exciter post.
Is there 12 volts DC on the solenoid exciter pin when the key is in the start position?
Eric
