A great way to disconnect power at the flip of a switch. I have had one of these on my Corvette for over 10 years now and it still works flawlessly, so I found these at Advance for my other vehicles. I recommend this product strongly.

The bolts that hold the lugs to the frame were stripped. Nothing was tight. Had to drill, tap and use bigger bolts. Should have sent it back but I'm tired of sending things...Read complete review

Comments about AutoCraft Side-Mount Battery Terminal Quick Disconnect Switch:

Side Mount Battery Quick Disconnect Switch.

There are several different styles of these Quick Disconnect Switches. They all function the same. I preferred the "Knife Blade -Type" for my application as opposed to the " Turn-Knob" switch. Both are good. The knife blade is heavy-duty and easy to operate. The plastic separator does feel a little flimsy and could be made stronger. I purchased the switch to easily check for parasitic drains, and to quickly disconnect battery power w/o having to unscrew the battery terminals. Be sure to grease the copper blade and connectors after installing. This will help keep it from corroding and keep it looking shinny & new. Installs in minutes ..(Warning: Be careful not to cross-thread the bolt when connecting to your battery). I had to replace the original battery bolt w/ a longer bolt for my application. Hope this helps. W.Alexander Bielaga, Griffin, GA

Comments about AutoCraft Side-Mount Battery Terminal Quick Disconnect Switch:

It is over a great product. It works for me flawlessly. The only downfall to the product is that it is a hassle to install, at least on batteries with the negative post on the left side (facing rear of vehicle). Both holes need to be threaded to allow ease of install for all vehicles. Instead of everything being able to connect in a straight line, I had to cross my connections and the vehicle negative just barely reached the bolt up hole. To some it may not be a simple hassle free install as that was the case for me but for some it may be done with ease.

Did not work for me

By

Comments about AutoCraft Side-Mount Battery Terminal Quick Disconnect Switch:

Had it for a couple weeks now. Installed it on the ground side. One day the first week the truck wouldn' start. After I pushed the arm to touch the end of the mounting screw it started. Today it would not start again. I couldn't even charge or jump the battery with the device on it. Played around with it for a 1/2 hour and finally took it off the battery. Wala! It started.

I really don't understand why it doesn't work but I don't have the time for a product that works 50/50 out of the box.

WIRTHCO SIDE-MOUNT BATTERY DISCONNECT

By 

from Raleigh, nc

Pros

  • Made It Work

Cons

  • Difficult To Use
  • Not Functional

Best Uses

    Comments about AutoCraft Side-Mount Battery Terminal Quick Disconnect Switch:

    Used on Chevy 1 ton truck, the 3/8x16 bolt that attaches to battery side terminal was too short , substituted longer bolt( 3/4"L), also substituted longer battery cable bolt( my existing battery cable bolt was too short to attach securely to the threaded terminal of disconnect switch.)The switch was non functional for my truck out of the package. Works well when installed. I had substitute bolts and washers on hand to make it work. Without these ,I would carry it back and be ticked off. I would not recommend this switch as sold.

    Comments about AutoCraft Side-Mount Battery Terminal Quick Disconnect Switch:

    Better quality than I thought. I had to tighten the screw to one of the contacts as it was a bit loose, and the supplied bolt is too short to use with the washer supplied into the side port, but worked well otherwise for my GMC truck. Made in USA! Cheaper than other places, too.

                      Yes the switch will work on 24, or 36 volts. Need to know ampacity, and terminal size. I would not feel safe about AC, only DC, and would not use it under load, like starting or stopping an electric motor.
