Battery Disconnect

[Minkota]

I am looking to add a battery disconnect (that I do not have to go under the hood to disconnect) I was thinking of adding the

Painless Performance Remote Master Disconnect Kits 30206.

Has anyone installed one of these? How did it work out?

Thanks

I use the underhood one but you could buy all of those pieces for half that price. It looks simple enough.

I have looked to piece it together but a decent Latching Solenoid is around $60-$70 by itself so you end up paying about the same with shipping.

Just installed one in my Toyota over the weekend. I had to make new battery cables anyways. Still have to wire in the button somewhere. It doesn't disconnect the battery completely, but isolates the starter to a possible hidden switch.

You don't need a latching solenoid. That's a Ford starter solenoid. You need a push on/push off SPST switch or even just a SPST toggle switch.

Had my local electronics guy that does stereo and remote starter installs put a kill switch in my 72. No buttons to push or any special wiring showing. Just do something and you can start the truck and if u don't do it the truck will never start.

I am not looking for a "kill switch" my MSD Box already has one. I am looking for a Battery Disconnect similar to what would be on a RV Motorhome.

All of my vehicles are like this.

Unfortunately, it's not on purpose and I don't always know what the "something" is.

Give us an example of things that can be done. Is it a sequence of events?

Also, a link to the device.

Its my understanding that using a regular solenoid will have a small drain on the battery where a latching solenoid will not because it uses a magnet. possible I misunderstood. At times my truck sits for months without starting because I travel alot for work. I typically just disconnect the battery but was looking for something that did not require going under the hood in case my wife or son need to move it while I am away.

When the switch is in the off position the circuit will be open, the solenoid will be withdrawn and there is absolutely no current drain.

These work well I have a few: https://www.67-72chevytrucks.com/vbo...&postcount=257

i would like to be able to disconnect the battery without going under the hood.

I bought and use that on your recommendation.

Looks like a great product, I'm probably ordering one today. Painless makes good stuff.

There is a 30204 model available on Amazon I will check it out..

I put one of these on the side of my battery tray.
https://www.autozone.com/starting-ch...-150/32369_0_0

Ran battery cable to a binding post. From binding post I ran to starter and to the 150a circuit breaker. I then connected all accessories and the factory fuseable link to the switched side of the breaker.

I discovered after doing this, my LS swap harness picks up power at the starter. At least I can quickly disconnect power to all of the factory wiring and other accessories. Just not the starter and engine computer.

>>Its my understanding that using a regular solenoid will have a small drain on the battery <<

A regular ford type solenoid would not have current draw when not energized, but requires 8-10 Amps to energize. That means an extra 10 Amp draw on the charging system all the time you are driving.

Not using a latching solenoid would be a bad idea.

I wired in a Moroso 74102 battery disconnect switch. Very heavy duty. I mounted in on the front frame rail where I can easily reach it by reaching under the truck, but it's not obvious to passers by.

OP Above suggestions may or may not cover your need as you have indicated in subsequent post. What is the need for battery disconnect? Do you have an untraceable draw? Security? Good disconnects used on race cars do fine and have a second circuit to ground the alternator for protection should the switch be opened while engine is running. This avoids alternator diode damage while engine runs down and alternator stops spinning. https://www.pegasusautoracing.com/gr...pID=SWITCHBATT

The main reason for the battery disconnect is because I do not want to leave the battery connected for the long periods that the truck sits unused. I am wanting something that does not require going under the hood in case my wife needs to move the truck while I am away.

I have had many different race cars and am well aware of all the different switches that have been suggested. Those switches just do not fit the need that I am looking for.

I posted the Painless Performance Remote Master Disconnect Kits 30206 as it seemed to be what I was looking for and was curious if anyone had used it before.

I always manually disconnect the battery after every use. I have two trucks and never know when I'll drive them again after using. I always check my fluids before driving, so it's not too big a deal to reconnect the battery. Change up your parking situation before you go away?

How does the Painless kit wire into a AAW harness to allow the Dakota Digital, ECM, and radio to maintain power?

There is a 10A fused wire that has constant power. those would be the only battery drains. I chose not to connect that on mine.

[1971Stepside]

Thank you Minkota. I was looking at that diagram and was wondering where in the AAW harness I would run that wire to keep those (radio, dakota digital box, and ECM) powered. Would I need to run to each of the leads for those items or is there a way to go directly to the fuse block with one wire?

My truck has a dedicated harness and fuse block that I wired in separate from the OEM Fuse block. I did not want to run the new technology thru the old fuse block, but that was a choice that I made not necessarily required. I could have wired it the the constant wire but I chose not to do that. I may still do that but for now it is wired the way I need it to serve my needs.

Eventually I will be replacing the old fuse block with an upgraded block. but for now the old still serves its purpose.
