Title: Going to install one of these on my car
Post by: deathsled on December 11, 2023, 11:56:33 AM
With all the talk of fires and disappearing vehicles I was recommended by a friend to put one of these on my car.  He is a just recently retired airline pilot having flown big birds so I trust his judgment having survived 30,000 hours of time up in the skies.  I will let y'all know how the install goes.

I know a couple of people who have installed those. Good idea.

I would recommend the knife-blade style instead.

Those have been available since at least the early 80's. They originally were advertised as a theft deterrent. You unscrewed the green knob and put it in your pocket so no one could start your car. Of course it can be easily bypassed . Later consciences supported it being used for log term storage where a slight draw of current from the car would keep the battery from being drained.  A added benefit is that during storage and with the disconnect used there is no chance of a electrical fire from a faulty circuit that is normally powered by the battery.  Yes as has been stated corrosion can build up and common sense maintenance is a given . The basic one pictured has drawbacks but  can be  easily cleaned and less obnoxious looking compared to the knife blade lever type . But that is just my opinion.

It won't prevent a fire, just delay it until you are driving your car!

Any car thief that can't get past that isn't going to have a very successful career.

I've always disconnected the positive terminal.  That way I know 100% there's no chance of electricity in the system, via a possible short.

What's the benefit of removing the negative terminal instead of the positive?

It's hidden under the edge of the floor mat. Don't use a disconnect in a car that has a brain (OBD I (?) & II). it will have to relearn every time you reconnect.

Post by: greekz on December 11, 2023, 05:12:59 PM
The negative cable provides the grounding for the entire car via the engine block to the firewall.  Without a ground, nothing in the electrical system functions.  Disconnecting the positive is another way to isolate the battery, but the car is has a ground.  I just prefer removing the ground.
Title: Re: Going to install one of these on my car
Post by: Side-Oilers on December 11, 2023, 05:31:10 PM
Greekz, thanks for your reply. 

Agreed, in a properly operating electrical system, disconnecting the positive or negative produces the same absolute no-current-possible results. 

But, could there be an occurrence where there's a slight short somewhere in the system that could manifest into something bad if the positive is left connected?  I'd think that might be possibility.

That's why I choose to remove the positive.

I guess I could remove both cables, then been able to sleep completely worry-free.    ;D

I have never felt any anxiety by removing only the negative cable.  I suppose totally removing the battery from the circuit could be one more step to a peaceful nights sleep.  We all have to do what feels comfortable.

I have been using the NAPA disconnect for years without a problem.  Definingly prevents any battery bleed.  Didi not use it on the 65 Mustang GT due to annoyance of having to reset the the clock each time.  I used a trickle charger instead which was disconnected when I was not going to be at home in case of fire.

Sure you mounted your safely but it reminded me of a similar one mount on a 67 Shelby a few years back I found during an inspection. Someone didn't think it through IMHO. Might have been very exciting when the driver went to engage the parking brake and the cable was pulled against the post or cable end(s)

Battery kill switch is installed.  Video is in the link.

The benefit of said switch works where your car is parked long enough for a thief to steal your car but not long enough for the thief to diagnose and remedy the problem.

counselor we are so impressed with your videos,  the tone, clarity and the eloqounce of your speech made for us the common folks easy to comprehend and follow.

your proper usage of P. P. E.s gloves, glasses was on point to not only illustrate the proper installation,  but a proper safe installation.

we give you two thumbs up !

if you ever leave the legal field, you could possible transcend as the  "Mechanical Ghuru"

best of luck !

You're hilarious, Tony.  I am barely above putting a nut and bolt together.  Any mechanical knowledge I have, which is entirely scant, is all derivative from all those around me and those who existed before me.  I have invented nothing, built nothing, welded nothing.

The + & - posts are different sizes on the battery. Install the cut out on the one it fits best. I prefer to install between the ground cable an grounding location.

The negative fit best and appears to be the suggested terminal on the switch.  Everything works as intended.  How effective it might be remains to be seen.  I think it will deter a fast theft where you park the car for a short duration of time that is long enough to allow a theft to occur but thwarts a thief because you are not long enough away from your car for the thief to diagnose the problem and find a remedy.  Plus the manual transmission does not help auto thieves these days.  Anything that buys you some time is in the positive ledger.  Plus the battery discharges more slowly and the risk of a short leading to a fire is reduced while parked.

Post by: shelbymann1970 on December 12, 2023, 09:08:42 AM
So what little I know about electronics I'd say when you disconnect the negative cable you have now disabled the electrons flowing out of the system therefore any short that may occur doesn't because without the loop of the negative system on the battery there is no chance of drawing anything from the battery at this point to cause a fire. Real easy to check. ground out a courtesy light switch with the neg off and then the negative on-no blowing of the fuse so the whole system is dead. Never disconnect a pos cable first. Always the negative. Reverse order when installing.

I use a rubber cap just in case while using wrenches they do not accidentally bridge between the positive and negative terminals.  I have noticed as I advance in age, my dexterity is not what it used to be.

Google remote battery disconnect switch. you will find several different kinds and they come with a key fob type thing to carry and just push a button and it will disconnect. Come back to your car and hit the button and you're ready to go.

FYI In the process of connecting and disconnecting the battery cables the negative cable is much less likely to crack from fatigue compared to the positive cable. That is one reason to use a battery disconnect contraptions to lesson the risk. This is very important to consider when using rare original assemblyline positive battery cables. Not so much when using easily replaceable repro cables. The genuine original Ford made negative battery cables are really as rare as hens teeth. There have been many in recent years that have been duped into buying first generation Marti negative battery cables (before he started using metric wire) as genuine and big money given their patina after 30+ years.

FYI although authentic assemblyine looking battery cable terminals look to be made out of the same material ,the positive battery cable terminal is softer solid lead where as the inside of the negative battery cable is made of less likely to fracture brass before being tin/lead dipped.

      Just for thought:

      Actually as defined the current flow is the directional movement of the free electrons thru a  conductor, but realize that since electrons are negatively charged they actually flow in the direction towards the positive terminal of the battery!   ;)

      Ever wonder why many older vehicles were "Positive-Ground"?   ???

They were originally advertised as a theft deterrent. You unscrewed the knob and stick it in your pocket and walk away. Not advocating for how effective just relaying what it was originally advertised for.

It makes a quick theft much more difficult unless the thief has one in their goodies bag which is unlikely. It will take them time to figure out the problem which may be enough time to catch them before they succeed.  The device won't prevent a theft but it sure will slow down a thief's methodology.
