Are electric power disconnects legal as a means of total power disconnection on race cars? I'm talking something similar to an RV where you can turn the power on and off with the push of a button and not have the cables and mechanical switch. Kevin | ||

There is some good info here But you may get some different replies now. I am also looking for something that doesn't need the large external switch. My Cutlass doesn't really have a good place for it and not have to chop into my rear bumper. | |||

I've never been given a hard time at a few tracks with strict tech. The push off switch in the back kills the car. I use cole hersee solenoids, Curtis used trombetta. Solid state battery disconnects are we way to go but expensiveThis message has been edited. Last edited by: SP 124X, Denis LeBlanc | |||

Denis is correct on mine. Here on page 3 shows the way I did it. I love my set up. It worked extremely well all year. https://drr.infopop.cc/eve/for...657040007#7657040007 ____________________________ 2017 and 2018 Osage Casinos Tulsa Raceway Park No-Box Champion 2018 Div4 Goodguys Hammer award winner | |||

So some of the mechanical switches are rated at 30 Amps and the electronic ones are rated 500 Amps or more. This one here is 500 Continuous and 750 surge. https://www.amazon.com/gp/prod...A39LCRHCD8QJN3&psc=1 https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability.

Who the heck is pulling even close to 750amps?  This message has been edited. Last edited by: CURTIS REED, ____________________________ 2017 and 2018 Osage Casinos Tulsa Raceway Park No-Box Champion 2018 Div4 Goodguys Hammer award winner | |||

I do not know any pulling close to 750 Amps but most are pulling more than the 30 some of the mechanical are rated for. https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability.

Mine is rated at 200 and more than covers anything I need. 500 would definitely be safe. ____________________________ 2017 and 2018 Osage Casinos Tulsa Raceway Park No-Box Champion 2018 Div4 Goodguys Hammer award winner | |||

The Cole Heerse 200 AMP is complete acceptable. It will easily tolerate starter draw AMP. I use two cutoff switches, one in the rear that remains "on" during the race day, and one in reach of the driver that can be turned on and off as wanted. I usually turn the drivers switch off while charging the battery. Larry Woodfin | |||

I believe those electric power disconnects make great replacements for those using ford type starter relays. | |||

Same thing better price.. I assume these are continous duty. Is there a way to wire them that allows you to turn them on/off from two switches. Not turn main swith on and leave it then second switch interupts the main one. (does that make sense?) I am electronics illiterate..

Another question on the electrical cut off. Can it be left on all day like I do the mechanical one? It doesn't get hot? Dave "It is usually futile to try to talk facts and analysis to people who are enjoying a sense of moral superiority in their ignorance." -Thomas Sowell | |||

I believe you won't have a problem. It's just a battery isolator. The fleet I work on have them installed in their vans and they run all day. I am just starting to replace some in the vans that were built in 2015. They will get very hot when they short out. Ken | |||

David, just remember that you have an electrical draw while they are on. I don't want mine on all day. I turn it on when I get in and off before I get out. That's why I have one of the switches in the ****pit. ____________________________ 2017 and 2018 Osage Casinos Tulsa Raceway Park No-Box Champion 2018 Div4 Goodguys Hammer award winner | |||

On my Altered I have the mechanical switch is on the back which I leave on all day at the races. I also have an electrical switch that I use to kill power from inside the car. My electrical switch is a Cole Hersee?? and I think I am going to change it out to higher power one like above. https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability.

Dave, it is a 100% duty cycle relay but it does get hot and does have some draw [maybe 2 amps] so I turn it off when the car is parked. Larry Woodfin | |||

But will these isolator solenoid switch coils handle 16 volts or up to 18.5 volts when running an alternator and live long term? | |||
