Weird electrical fault.

[Jamming]

Was running my brand new JD 3005 today and all of a sudden it just shut off. Took the exhaust stack off opened hood. Humm don't see ant loose wires. Checked the safety switch, looks fine. Turn key. Nothing. try in and out of gear, still nothing. Pull fuse box cover and find a blown 5 amp fuel pump fuse. Look at fuel pump looks fine. Then I put a new fuse in after a 10 minute walk to the shop for tools and fuse. Starts right up and runs about 3 seconds, blown fuse again. Wtf ! So then I unplugged the fuel pump and put in a new fuse, I make it back to the shop and call my dealer. He ordered a new pump. Well I found the problem moments later.

The plug that goes into the pump was touching the little ear that was sticking out from the fuel hose clamp. In turn was blowing the fuse. Why post this ?

Well incase someone else might have a weird fuse failure like this they can make sure the plug is away from the hose clamp, the little crimp style.

Was the hose clamp attached to metal or on rubber touching metal and the pump?
EDIT- I bet it was touching the pump and electrical contact...

Looks like the hose is braided so I think it is well grounded. I was sitting in my house thinking the same think, but they look braided.

That would do it!!!! GM went that route inside teflon because of static spark fires when changing fuel filters on 1984 Celebrity 2.5 Liters.

I think tomorrow I will heat shrink the connector to prevent any chance of it shorting out again.

Good detective work! Fortunate that you weren't off in the woods a mile or so from the house...

Great info for other owner's as well! :thumbsup: Something for them to consider if their 3005 stops "pumping".

Spent a couple of weeks in Twisp about 30 years ago. Beautiful country! Could only afford to visit - never buy - that's always a problem when you're young...

Always find it amazing that where I live I can drive two hours time and go from a rain forest at 80" of precip to 6" of precip. Twisp is a great place to still buy in Washington. About $80-200 a square foot average.

Good find. A fuse blowing immediately indicates a direct short. A pump failing in such a way so as to put a direct short on the power input would be highly unlikely. I mean almost never. When there's a direct short, always suspect the integrity of the wiring and physical connections. Good job, and the price was right too!

I will also post some pics tomorrow of the exact location and plug.
