Battery isolator switch


Recommended Posts

Posted
Ages until I get to install this I am sure, depending on the position. I bought one of Ebay, comes with the necessary resistor to protect the alternator circuit. But back to my question. I have seen these on the outside of vehicles but I am sure that would not be acceptable by the SVA.  I think the MSA regulations or whatever state that it must be reachable by the driver and easy for marshalls. So the question is where have people positioned their's where it is acceptable by all! I was think inside the car on the rear bulkhead at the top but a) not easily reachable by the driver and b) probably constitute an SVA failure

No idea about the sva but for MSA events you have to be able to reach and opperate the switch whilst fully belted in your normal driving position.

Mine is dash mounted.

Mine is on the dash, on the passenger side. However, I don't think the car went through SVA with it in that position...

Thats only because your car never had a SVA !  :D  :D  :D  :D

Might be a better option to fit your switch after SVA - by fitting one before it only gives em something else to check and something else to fail  ;)  :)  ;)

Mines on dash towards passenger side where I can reach and clearly identified for marshals  :D

Yep I suppose I should resist goodies (event safety ones!) until after the SVA.

Mine's on the bodywork under the drivers side wing mirror along with the extinguisher pull handle both with big stickers next to them so marshalls can see them easily. I figure'd if I need to kill the engine while I'm concious, I can turn the key off but if I'm unconcious I want the marshalls to find it easier. It seems to get through scrutineering okay.

I also noticed the caterham Graduate series all have them fitted here - not sure if they have an additional one on the dash though ?

Like leaving the hood/tonneau studs and the sidescreens until after SVA, it is best to keep the car as minimalist as possible for SVA.

Anything in the passenger cabin outside the zone protected by the steering wheel or outside the car and accessible by the SVA dolly (an aluminium dome about the size of a baby's head or an adult knee with a short stick handle) must have a minmum radius of 5mm to minimise the likelihood of cut injuries during an impact.

Leave it until after SVA.

Mines fitted under drivers mirror on aeroscreen.

A bit like Rich....I figured Marshalls always approach drivers side 1st in event of impact etc so having it that side made it easier/quicker to find

Hi Adam,

I fitted mine Pre-SVA onto a panel that sits on top of the tunnel, just under the lip of the dash i.e. slightly recessed from the dash.  No issues with SVA:

If I was building from scratch I'd want to fit it straight away to get all the wiring in place. You could always take it off for the sva and just tape it up behind the dash or even remove it and connect the terminals together with a nut and bolt and tape up the connection to prevent shorts.

Yep, I was kind of thinking if putting in the wiring first.

I've put mine  between the seats through the panel behind the seats hidden away from prying eyes and fairly easy to reach. can provide photo.

Car is now sorted and SVA booked . Drove it for the first time last night and was grinning from ear to ear :love:  :love:  :love:  :D

Hey Mate,

Good to hear from you. Glad you have the clutch sorted now. Hopefully you will not  have to remove the engine again!

I remember the position of your switch, and was going to do the same as it is close to the battery, seems reasonable idea, but then I tohught, erm, that SVA man, better watch out for him! If I were you I would either remove before the SVA. Although Arguably you could not hit that with your body in an accident as it is behind you, maybe close enough behine the seat, but still an opportunity to fail.

Other thing is I have soruce an engine! I have just bouhgt one of Ebay a 1989 3.9EFI RR. Comes complete with EFI, etc. I have plenty of time with my build so I shall probably take it to bits and rebuild it.
