I would like to fit a battery cut out (removable red key type) to my +2. Currently, I have one fitted to the battery in the boot which is a bit of a pain as you have to open the boot each time to get to it.
Has anyone fitted this type of cut out switch anywhere else neatly in the car ?
I have seen on some of the race cars that they drill a hole in the front wing. This must be on the POSITIVE terminal ?
I would like to fit mine to the NEGATIVE termonal as recommended and hence towards the back of the car is better.
Hi! I fitted one on a customers’ +2,in positive battery cable,just ahead of seat(make sure it clears seat when fully foward).this was on a small bracket I made,bolted to the floor,with ,i think ,the switch hidden behind sill cover/carpet.easy to reach,not much to see when key removed either.
Don’t think it really matters which cable(pos or neg) that you cut,most rally/race cars i’ve worked on cut the pos.

Not sure how easy it would be on a +2 with their different sill structure but on a 2 seat Elan with the battery cable coming down the sill it’s relatively easy to punch a hole through the carpet covered fibreboard trim and rivet a bracket to the back so that the cutoff switch just pokes through into the car.
It is on the main +ve cable as it passes through the cabin on it’s way to the engine bay. The switch is fitted to the panel behind the door and is located below the seat belt exit slot. The fitting requires one hole to be drilled in the panel. When the key is removed there is hardly anything to see.
When the key is fitted it faces down the way and points towards the little arm rest thingy (technical term) in the panel. It’s dead easy to get to.
This switch kills all power to the car (except a little fused power take off socket in the boot which is wired straight to the battery. I use it to plug in a trickle charger in the Winter)
To fit one to the -ve (earth, I presume) would involve a fair bit of cable if the switch was to be located in the cabin. Is it worth the bother and maybe the extra resistance?
I have one of these, it is mounted next to the starter solenoid so I just reach up under the dash and pull it out, I find it it quite handy and hidden from view.
Hi Jason,
What is the little blue connector - doesn’t seem to be connected to anything? Also how does it operate and where did you purchase the switch? Not easy to fit upside down under the dash is it.

Just guessing that the Blue connector is an emergency bypass.
For what it’s worth, I have a Cut Out switch fitted to the earth connection in the boot of my Plus 2. I’ve paralleled the switch with a 10A blade fuse, this is enough to keep the ancilliaries alive, but will blow if you try to start the car without the cut out switch fitted. The fuse location isn’t very obvious. Crude, but effective security measure.

thats exactly what I have!!!
works a treat is easy to use and is very discrete indeed…
mine had a bypass fuse fitted too so that the radio I have didnt loose its memory…however if you tried starting the car it blew the fuse and the radio forgot everything so i bypassed it and its now surplus!!!
cheers

I had one in my old plus 2 for years. Mounted it under the dash to the left of the eyeball (RHD). Was an easy reach and I never had to worry about coming back to a flat battery. With the key out you would never know it was there. I prefer the units with the brass pin on the key, but I have never had any problems with the plastic ones. Wherever you mount it you want to be able to reach it very easily or it will pee you off after a short while!
Yes the blue connector was to power the alarm, as you rightly say without this connection there would be no power to the alarm unit.
It is the brass tab key type, most motorsport places sell them and it seems to work well.
This one was fitted by the PO but I would recommend Minispares they sell them for about ?20. I use them for quite a few parts and have found them very good.
