MyVans Your Vehicle Solution Ford 8N tractors are known for their reliability and durability. However, like any other machine, they may develop issues over time. One of the most common problems with these tractors is a faulty ignition coil. If you suspect that your tractor’s coil is not working correctly, you can test it yourself. In this article, we will show you how to test a coil on a Ford 8N tractor.
Gather the Required Tools
Before you start testing the coil, you’ll need to gather some tools. Here’s what you’ll need:
- A multimeter
- A spark tester
- A screwdriver
- A pair of pliers
Step 1: Disconnect the Battery
The first step in testing the coil is disconnecting the battery to avoid accidental electrical discharge. Locate the battery and remove the negative cable using a pair of pliers.
Step 2: Locate the Coil
Next, locate the coil. It is typically located near the distributor. Once you find it, use a screwdriver to remove the coil wire from the distributor cap.
Step 3: Test the Coil Resistance
Using a multimeter, set it to the resistance or ohms setting. Touch the positive and negative probes to the positive and negative terminals of the coil, respectively. A good coil should have a resistance reading between 6,000 and 15,000 ohms. If the reading falls outside this range, the coil is faulty.
Step 4: Test the Coil Output
Using a spark tester, attach one end to the coil wire and the other end to a good ground. Crank the engine and observe the spark tester. If it shows a strong spark, the coil output is good. If there is no spark or a weak spark, the coil is faulty.
Step 5: Check for Cracks or Damage
Inspect the coil visually for any cracks or damage. If you see any, the coil is faulty and needs to be replaced.
Step 6: Check the Wiring and Connections
Check the wiring and connections between the coil, distributor, and battery. Ensure that all connections are tight and free of corrosion. Any loose or corroded connections can cause issues with the ignition system.
Step 7: Reconnect the Battery
Once you’re done testing the coil, reconnect the battery by attaching the negative cable to the battery terminal.
That’s it! You’ve successfully tested the coil on your Ford 8N tractor. If the coil is faulty, you’ll need to replace it with a new one. Consult your tractor’s manual or a professional mechanic for guidance on how to replace the coil.
