Where is the neutral safety switch on a John Deere 4520? Alright, so you’ve got this issue with your vehicle where it keeps blowing the fuse when you try to crank it, right?
Well, here’s a little trick you can try: find the neutral start switch on the right side of the transmission. It’s this little guy that’s causing all the trouble. Now, what you wanna do is unplug the two wires from the switch and then connect them together using a jumper.
Once you’ve done that, give it another go and see if your car cranks up without blowing that pesky fuse. If it does, well, there’s your culprit – the neutral start switch is acting up and needs to be swapped out for a new one. It’s a bit of a hassle, but hey, at least now you know what’s causing the issue and how to fix it.
What is error 81 on John Deere 4520?
if you’re seeing a code 81 pop up on your dashboard, that usually means your fuel level is running pretty low. First things first, take a peek into your fuel tank and make sure you’re not running on fumes.
Once you’ve done that, it’s time to get down to business. Check the fuel pressure at the inlet side of the fuel filter. That’s where you’ll find out if everything’s flowing smoothly or if there’s some hiccup in the system causing your low fuel situation. So, go ahead, give it a look, and let’s get that fuel situation sorted out pronto!
