Troy Bilt Pony Ignition Switch Wiring Diagram

The Troy Bilt Pony is a popular lawn tractor with a 15.5 horsepower Briggs and Stratton engine. One of the most common problems with this mower is a faulty ignition switch. If your mower won’t start, it could be due to a bad ignition switch. In this article, we’ll discuss the Troy Bilt Pony ignition switch wiring diagram, including how to diagnose and fix common issues.

What is an Ignition Switch?

The ignition switch is a critical component in starting your mower. It’s responsible for sending power to the starter solenoid, which in turn engages the starter motor. The ignition switch is also responsible for shutting off the engine when you turn the key to the off position. Ignition switches can wear out over time, which can cause starting problems or other issues.

How Does an Ignition Switch Work?

The ignition switch has several positions, including off, run, and start. When you turn the key to the run position, power is sent to the ignition coil and fuel pump. When you turn the key to start, power is sent to the starter solenoid, which engages the starter motor. As soon as the engine starts, you release the key and it springs back to the run position.

Common Ignition Switch Issues

Ignition switches can wear out over time, which can cause starting problems or other issues. Some of the most common ignition switch problems include:

Issue Symptoms
Worn contacts Difficulty starting, intermittent starting problems
Loose or broken connections No power, intermittent power loss
Key won’t turn Ignition switch fails to turn or won’t turn all the way

How to Diagnose Ignition Switch Problems

If your mower won’t start, you may have an ignition switch problem. Here’s how to diagnose the issue:

  • Check the battery: Make sure the battery is fully charged and the terminals are clean and tight.
  • Check the starter solenoid: If you hear a clicking noise when you turn the key, the starter solenoid may be faulty.
  • Test the ignition switch: Use a multimeter to test the ignition switch for continuity in each position.
  • Check the wiring: Inspect the wiring for loose or broken connections, including the ground wire.
