I'm going to fit a couple of these as remote door lock actuators in my middy (saves mechanical linkages etc) and wondered if anyone knows what current they draw to get a reliable action. I want to have the doors powered by a separate (small) battery which will be independent from the main battery and need to know how big it need to be.

there quite high dont know exact figures but i know they pop a 10amp fuse

10A EACH ?? !!

Looks like I might have to rethink

Hi

Its probably the surge that blows a fuse, why do you want them off a secondary battery?

Adrian

I intend to use the battery cutoff switch when parked but if I close the doors with the power off I won't be able to get in the car.
I thought a secondary battery (the type used as backups in alarms) could be linked to the main one using a diode to stop it draining when the main one is switched off. That way I can always get in the car .............. which is nice

If they take 10A I might have to wire them direct to the main battery instead. Only drawback will be the flat battery scenario

i take it your havin no door handles or locks and that when you say parked you mean left in the garage as the solenoid wont drain it.

the best way to get over the flat battery is to hide a socket maybe a cigarette type(hella do some nice waterproof ones) under or somewhere accesable but no visable.
itll be handy for say trickle charging when your not using motor and especially so if you get a flat battery.

hella blugs and sockets

You could run them off the same battery, and have the battery cut off switch isolating the rest of the electrics. Still would have a problem with the flat battery scenario though if you left the lights on etc.

A friend had a similar setup, to get around the flat battery problem he had a a pp9 battery connector connected directly to the driver's door and hidden securely. A pp9 had enough juice to fire the door popper to let him in to the car.

Aha so it looks as though the 10A figure was a little ott to say the least - if a pp9 can operate a solenoid it can only be a few mA.
I think I will do as suggested and have a 12V socket discretely hidden somewhere for emergencies (and trickle charging) and have the solenoids bypassing the cutoff switch.

Thanks guys

Is it ok to have auto doors for SVA?

Adrian

TVR Chimaeras don't had door handles just buttons...

They wont pass mot normally. I know a guy who had to have a spare set of doors for his mot coz he had de-handled his car

Hmm ... interesting - so how do Chimaeras pass mot I wonder?

Hi

I sva'd my stylus with no outer door handles, just internal ones, but i didn't have locks. SVA man never mentioned it

My stylus and TVR's are soft tops though, maybe that helps?
