Battery Disconnect Type

[Iggy913]

I've searched and not found the answer I was looking for. I'm interested in installing a keyed battery disconnect for some increased security. Through research here I plan on installing it in the chassis ground cable. My problem is what unit will work for me? I've found several keyed switches but all say they're rated for some pretty low amperage, some only good for 150amps. Others are rated higher, around 500amps, but is that enough? The batteries have more amperage than that when starting the truck.

What are you guys using?

Call a trucking/tractor/marine supply company. Six Robblees, Larsco, tractor supply, just to name a few. They should be able to help you out.

These Folks have a large selection of disconnect switches:

Good question. I'm getting ready to install a keyed disconnect myself but I'm still not certain.

Another thing I was thinking... most people have posted that you should connect it to the negative side. If you connect it to the neg and the switch fails wouldn't that possibly destroy your alternator?

I bought one of my Deuces with a cab floor mounted shut off switch that is descreet and hidden and works fine. It is made by Cole Hersee, Littlelfuse Commercial Vehicle Products, 6421 FM 3009, Schertz, TX, 78154, 201-651-1845. When I re ordered the switch, I upgraded to one wghich has cylinder materials rated for outside service. I think the part # is 75904-03-BX It cost more for this nfeature. Go online to see the catalogs for all other trim s available.

I forgot to mention, it can be mounted in the cab floor, cylinder facing up into ther cab, near under the passenger seat, WHATADEUCE

whatadeuce that switch is a good one and will work well. But remember that switch is used in most all the heavy equipment/ tractors etc.ever made and the keys are all the same so every person that knows/operates heavy equipment will have a key that will fit your deuce. Here is what I have used for years and they work well. Mount it on the floor beside the drivers seat on the right and toss an old knit cap over it to sort of hide it some.

Thank You maccus, the best choice IS for an individual key.

Been discussed before.

Nowhere in that thread is the answer to the question that Iggy asked.

Also, the disconnect you posted is rated for 12vDC.

I appreciate all the help, it looks like Flaming River makes a heavy duty disconnect with a switch that can be locked in the off position with a padlock. That would help eliminate the issues of hiding the switch and a common key with other heavy equipment.

Cat and komatsu both make a lock with paddalock switch as well both are 24 volt rated and work well alot of larger dozers use these

Take a look at the Cole Hersee P/N 2484-19 weather resistance switch.
[h=4]Detailed Description[/h]

• Single Pole, two positions: Off-On. Silver contacts.
• 175A continuous, 1000A intermittent, 15 secs On, 5 minutes Off.
• Designed to prevent fires, tampering, theft, battery drain.
• Brass mounting stem, 3/4"-16 thread, 23/32" (18.3mm) long, fits panels through 3/16" (4.7mm) thick.
• Two 3/8"-20 copper stud terminals. Plated steel case, Hencol lock & two keys.

The starter is not going to draw anywhere near 1000 amps. Probably closer to 100, but I'm guessing more like 50- 60. Just because the batteries have over 1000 cranking amps does not mean the switch has to be rated for that as the electrical system will only pull what it needs, not whatever is available. Of course, if there is a direct short somewhere it can, but that will cause a fire in short order.

Here is a post on the lockable Flaming River switch I installed on my deuce. I have been very happy with this switch. At 250 amps continuous and 2500 amps for 5 seconds it should be able to handle just about anything these trucks can throw at it.

Happyland: What cable did you break with your switch, the positive or negative?

 

[Happyland1410]

My switch is on the positive side. Since I installed it I have read discussions making the case that breaking the negative connection is preferable but I have not had any issues with mine and have not taken the time to change it. FYI: I have used a marine type (Perko) dual battery selector/cutoff switch on my 1976 F250 4x4 for over 30 years without any problems and it is specified by the manufacturer to work on the positive connections.

Happyland: What cable did you break with your switch, the positive or negative?

 

[Rifleman]

When i contacted the switch manufacturer they too said it's best to place the switch on the negative side. The reason they gave me is if you should happen to ground the switch or cables while installing it you would not get an short to ground. The problem i have with using the negative side of the system is i have a solar charger, and if i disconnect the negative side my of my system then my solar charger won't charge my battery's. So it looks like i will be using the positive side to hook up my kill switch just like you are.
