To 'Time Delay' or not 'Time Delay'

[FordTruck]

I'm having trouble with my power tongue jack on the new 2008 Safari 27FB SE. When the jack reached it's full extension (up or down), the inline 30amp fuse blows. I've gone through many (non-time delay fuses) in only our 2nd time out with the trailer.

Dealer didn't have a clue as to whether a 'time delay' fuse would alleviate the situation. So far, their advice has been "don't do that" and the fuse won't blow. DUH !!!!!!!

I have the exact same problem with my trailer. Unfortunately the access to my fuses is damn near impossible to reach. I have burned thought about 6 fuses, and lose power to my brakes and fan at the same time.

If you find an answer....I am all ears.

I'm no expert on these things, but the unit is supposed to have a cutoff before it reaches the max/min point. We had a similiar problem after the batteries were dead in storage, and I had to crank manually.

Get your instructions out and look for the 're-syncronizing' page. When the motor is in sync with the jack, the problem should go away.

I looked everywhere for 'slo-blow' 30 amp fuses, and finally found them at a NAPA dealer.

Good luck.

You could substitute a 30A automatic reset circuit-breaker for the fuse. They're available at autoparts stores.

Took Arvin to the dealer this morning and they installed an inline automatic re-set circuit breaker. That should end the issue.
I'll take pictures of the install and upload them as soon as I get the camera out.

Really interested in seeing this. Any idea where I can get the part for my own install?

Thanks,

I don't know if they sell to individuals, but try Waytek Wire : Electrical Wiring Supplies & Industrial Products and look at the circuit breaker section.

If not, let me know and I'll get one for you with my next order!

Auto-reset breakers are standard auto part store stuff. They come with screw terminals or with ends to fit in a "Buss" fuse holder. Here some made by cole Hersee

The circuit breaker installed in our unit looked exactly like the center one (silver) in the picture posted by CM.

I think the comments by others that this is readily available at autoparts stores is correct. I took advantage of having Arvin at the dealer for some minor warranty work to have the circuit breaker installed. As it wasn't "original", I paid out of pocket for the install. Small $$$'s in light of the aggrivation factor for constantly blown fuses.

Hopefully, able to post pics in the next day or so.

Re-sync comes to mind. The limit switches should cut the motor off before the jack bottoms out.

Here is a pic of the circuit breaker connection. It is in the battery box. I hope this helps.

Sounds to me like it's time for the dealer to replace the jack! Never saw a fuse on the battery like that before for a jack. I agree with previous post that the motor should cut out before reaching the jacks extension limit both up and down. Get after them and let us know how you make out. Changing the fuse type will not stop the cause only delay further damage.
