What Causes Your Ford F-250 Neutral Safety Switch to Go Bad
The Ford F-250 neutral safety switch is used to prevent your engine from accidentally starting while the transmission is in gear. Without this device functioning properly, problems with your vehicle may stir up. Your F-250 may become inefficient, and driving it may cause you a great deal of stress. Here are some of the issues you might encounter once your Ford F-250 neutral safety switch goes bad:
Your vehicle's starter fails to engage once you turn the key in park or in neutral-the reason behind this failure is a maladjusted neutral safety switch, which has become loose in the mounting. As a result, the switch can't be rotated just enough to reach the park position the moment you turn the key. Thus, your vehicle won't start. You can correct this problem by simply adjusting the switch, though.
However, you must also consider testing your neutral safety switch to confirm if it is really defective. Sometimes, your vehicle's startup failure can be rooted from a malfunctioning battery. Use a voltmeter and a test light in going about this procedure. First, check the voltage of your battery. If it reads below the normal range, replace your battery.
The next thing you need to check is the starter relay wire. The test light should glow, as the connection on the starter selonoid is being probed and the key is turned on the crank. If it does not light up, shift your vehicle into neutral. If your F-250 starts, your neutral safety switch is definitely broken. In this case, you need to replace it.
When your truck starts in gear, you might want to check the contacts that could have gone bad due to moisture in the switch. Your switch may not be properly sealed, which then leads to a short circuit within the switch terminal. This short would go against the power-out terminal then to the starter. As a result, this condition causes your vehicle to start in gear. Check your contacts for any physical damage as well. Look closely for metallic debris and metal shavings due to wear.
