What causes voltage drop at ignition coil wheel horse?

What causes voltage drop at ignition coil wheel horse?

Replace any connectors, wiring or ignition switch that may be corroded and causing the increased resistance in the ignition circuit. The drop could be across the battery + to starter but if that were true, your tractor would probably not crank over.

Is it normal to have voltage drop at ignition?

With the key on, the voltage at the coil reads 11. A drop is normal since the coil is a resistor. yup you’re right. I pulled the wire off the coil and tested it and there was no voltage drop at all from the wire. As soon as I attach it back to the coil it shows a voltage drop.

What happens when you turn on the ignition?

Turn the key on and current will flow to the coil, but the ignition points have to be closed to complete the circuit. If the engine stopped rotating in a position that the points were open, there would be no connection to ground and there would be no draw on the battery.

What to do if there is no spark at the ignition coil?

Check for voltage output at the ignition coil. Disconnect the ignition coil wire from the distributor and install the spark tester to the wire and ground the tester to the engine. Crank the engine for a few seconds. If there’s spark, the problem is with the distributor cap or rotor.

What are the symptoms of a bad coil to distributor wire?

If you suspect a bad coil-to-distributor wire, there are two main symptoms to look for. If the engine stops and starts erratically while driving, or if it cuts out altogether and refuses to restart, you may have a bad wire between the coil and the distributor.

How to isolate a bad coil high voltage wire?

To isolate the fault, turn the ignition key on without attempting to start the engine and then remove the distributor cap. Ensure that the points are open and adjust a multimeter to the volts setting. Touch one probe to the insulated side of the points and the other to the engine block.

How do you replace the ignition coil on a lawn mower?

Remove the old ignition coil (armature) mounting screws. Disconnect the stop switch wire from the flywheel brake and remove the coil. Attach a replacement coil using mounting screws. Push the coil (armature) away from the flywheel and tighten one screw. Turn the flywheel so the magnets are on the opposite side from the ignition coil (armature)
