Main Battery Fuse

[Ronnie G.]

I think I may have blown my main battery fuse. Installing winch and touched the power cable to a ground by accident. I have no power to anything and a test light won’t even light up jumped across the battery.

Where do I look?

It’s on the battery
There’s also a few underneath the fuse panel behind the battery. And also some under that.

Mine is a 2022 model.

ok I can jump it off and everything is fine but if I kill it I lose all power.

First, I would disconnect the battery cables - (Neg) FIRST
and then with a meter check across the posts for voltage.
BUT - BE VERY CAUTIOUS and take an extra step and cover the battery with a towel and wear safety glasses.

Then I would disconnect anything power wise to the winch as I suspect a possible mis-wire
As a blown fuse would not cause- the test light not to light up (Pos to Neg) posts with the terminals hooked up.
I suspect you fried the battery (shorted) or a direct short in the winch or wiring
All 5Gs are the same in this area - the only exception is the Tremor has an additional fuse and related relay center.

If you have voltage with battery disconnected, then proceed

The Pos Terminal is a BMFL (Battery Mounted Fuse Link) and if you are not getting a voltage reading with it connected to the battery then you need to inspect it for damage.
if no damage noted then check the Ground Cable (entirely) for security.

Cable Runs
BMFL - Has a cable that feeds down to the HC Junction Box (This is mounted under the BJB) the Eng Fuse Box must be removed to access it.
In the High Current Box is the DC/DC Con Fuse and the BCM Fuse, it also has a cable that runs back up to feed the BJB (Eng Bay Fuse Box)

It is a Tremor.

Tremor- Only difference is that (to the right) of the (Green/Red) cable (Feed up to the BJB) the open spot (below) will have a 100-Amp fuse and cable running up to the (Aux - Upfitter) relay box.

Not shown in the pic below (forward and under the flap) is the cable connection from the BMFL to feed this junction -Connection (C) from above.
Plus, one other difference is the 225-Amp (Alternator) fuse above is replaced with a 300-Amp Fuse.


Again, if you are not getting anything (with a test light) Pos to Neg post, then the battery is shorted, or you have a dead short to ground.
This is why the battery needs disconnected and then test again; a meter would be best to see actual voltage.

Disconnected the battery and it’s toast, on my way to get a new one.

***Battery fixed it***
Thanks for the help!
