Yep that's exactly what I meant! Not ideal but better than nothing!

I will still install an mechanical-electrical disconnect - an anderson connection attached to a handbrake lever looks the most likely option.

For the clutchless couplers could you not use neutral as an absolute last resort?

For some reason I kind of thought without the clutch it might be hard to come out of gear under high load, never tried it?

By the way you mentioned an EV200 contactor, I looked on ebay and there appears to be a listing posted for this unit as second hand but 18 units available, from China maybe there old stock? only £32 +shipping sounds to good to be true, what do you think ?

I'll try pulling my vectra out of gear under load tomorrow. Don't think it's a problem.

I purchased mine from the below link and they have been perfect. If you need more than one purchase them separately a week or so apart to dodge customs (£60 is the low cutoff)

To cover myself, I'm not recommending them, just posting my experience.

Cheers,

Mike

mechanical pull of anderson connects while under load would not be *recommended*. without quick separation and magnetic blowout, chances are you'd have a hell of a arc and melt things.

take a look at your main circuit breaker(s), and see if you can add a cable pull, like an after market choke cable, to pull the breaker from the driver's seat.

...little off the original topic, but it caught my eye.

on the left of this image, note my main circuit breaker has a cable thru the toggle switch. I used a cheap choke cable run thru the firewall and mounted under dash next to window... visible to driver and emergency responders perhaps.

Sorry to stray off topic...

I agree completeley.

But.....

In the (fairly unlikely) event of a runaway, risking the possibility of a (large) arc and possible melting is much preffered than certain motor destruction by dipping the clutch or using neutral.

Its normal use will be for maintenance. It wont be used if it is ever damaged by an arc - the chances are that the controller has some serious problems in this case and will likely need replacing before the car is usable again.

If circuit breakers were more widely available then that would be my preffered solution, although I'm not convinced that once welded shut, they would be as easy to open as an anderson with a lever?
