455 won't crank - fuse locations?

[blackhawktek]

Guys,
We have a 455 that was running great last week, but now it won't turn over. The battery charger says its fully charged.
Here is a short video: John Deere 455 will not start - YouTube

When you press the brake and turn the key, the glow plug light comes on, then goes off like it should. However, when we turn the key to crank, nothing happens. I have checked the coolant, and even the button under the seat which we had had some issues with, but it all checks out fine. It just will not start now.

This online manual has some steps to try: Troubleshooting
I am just not sure where these fuses are located. Have you all had any experience with this issue?

Thanks

I first would suspect the battery...if it is over 3 years old, then I'd replace it.. or at least pull it and have it load tested.

I would say follow the power, from the battery, find where the starter is getting power and check all the connections, there could be fuses or fusible links to check.

You can unhook the battery and ohms test the wire from the battery to the starter to see if there's a break somewhere and narrow down where the issue lays.

My dad has the 445 and I'm not quite familiar of a fuse box in his but all the fuses in my Husqvarna are all in line, I had my Husqvarna die one day, found a inline fuse hiding, replaced it and all is good.

Also check the wiring on your key switch, make sure all is hooked up and something didn't rattle lose on you.

To make sure it's not the battery you can jump the tractor, there was a guy on here that had a 4300 that when jumped would fire, off battery only the instrument panel would light, he cleaned the snot out of his battery connectors and terminals, fixed the issue, the connectors had a buildup insulating it from the battery terminals.

simple test for the battery is to watch your headlights. If they stay bright when trying to turn over then it's not the battery or the battery terminals.

That looks like a good test.. will try to remember that..

Appreciate the input. We will give these fixes a go and see whats up. The battery is from '13, so that might be the issue after all. Do you all normally buy OEM? I believe this last battery came from Walmart.

I buy Deere batteries.. but that is prolly just me.. If a '13 bat, then my suspicions are confirmed that is it. Chargers "say" they are fully charged, but doesn't mean they are and can handle a load.. from what I've learned over the last 60 years.

Don't go out and buy a battery just yet, put a volt meter on it and see what it's showing, if it's 12-14v it's good, much below 10v throw it on the charger and you might get another season out of it.

As far as batteries go, seems 4-5 years is about all there good for if not properly maintained over the winter. But normally if it's a dead battery, it will try to start or it will click, you don't even get that which points me at the starter or a fuse disabling the starter from trying.

I just played it again with volume all the way up and it does sound like there was a partial crank in the beginning then nothing. Idk
