Hey everyone,

So I picked up a Superwinch TS15500 Winch yesterday. Serious piece of equipment it's hard to manhandle around.

Anyways the specs state that at peak pull it draws 440 amps. To a relative noob when it comes to electrical stuff this seems like quite a load. Now I would always have the truck running when using the winch and on high-idle to get the alternator putting out some good voltage.

I know how easily damaged things such as the FICM are when they are robbed of power on our trucks. I already have a fixed FICM from Ed, but I don't want to put that in jeopardy.

What are your guys thoughts? Are my worries unfounded?

Thanks,

Nate

 

Nate, that is a typical draw for such a big winch. Remember that would be at full load only. If your that stuck, take your time and don't do long pulls.

Technically, your 2 battery system with a stock alternator will do.

If I were to do this mod, I would make sure I have at least 850 batteries and a 140 amp alternator.

I run the 270 DC power now with 850's...

 

You might even want a 2nd set of batteries with an isolator so you mot pulling
from the truck main system batteries. Now if you not going to be pulling all the time
you could always use the the BCP if you year supports that. What it does is boost the
RPM for more alt output during heavy loads. If you don't have that opting then
a high idle mod would help.

Forgot to mention, the winch will not work with all that excessive cladding tape exposed on your Excursion.

 

refer to the owner's manual regarding duty cycle and multi breaker install for winch safety.

 

Thanks for the info guys.

I do have two 1000's in good condition, however only have the stock 110.

Will research different options and repost.

Thank you for the help

 

Ford spec indicates that lower than 9.3 volts for more than 5 seconds is not acceptable. We'd say that 9 point anything is all bad.

Your 110 amp unit only does about 65 amps at idle, a good chunk of which is being used in just keeping accessories and the base motor running.

I'd strongly consider the battery isolator already mentioned if you are planning only recreational winching.

If you are planning more than that, a larger alternator is in order. We commonly recommend the 270 amp unit (http://www.ficmrepair.com/index.cfm/...prod/prd20.htm) for winch applications combined with a high-idle mod to limit draw-down to about what the glow plug draw puts the batteries at post cold start-up in stock alternator applications (about 12.1V).

Of course, use of a ****** block goes a LONG way towards limiting the loads that winch would ever see.
