Wedge boot lock mechanisms...

[mrzigazaga]

Hi Peeps...Got some info that i want to share on the parts list as regards to the solenoid for the boot lock...I know the 280i had a cable but was the early 350i cable or button?...Cheers..Ziga

What about part numbers/sources ?? OK.

I reckon there are many solenoids which would work, have seen many Ford and GM types which would only need the right mounting bracket....

[adam quantrill]

My two 1986 350i's were both button, but there were 4? years before that.

[mrzigazaga]

A fellow Wedge friend has replaced his solenoid...They were Ford fiesta..

[RCK974X]

Those are actually motor driven ones, I've seen them on a few cars - I thought they were aftermarket ones.....
They need a controller as they have limit switches in them, they may burn out on a pushbutton.

The true solenoid ones are typically a lot smaller than that - useful for tight spaces....and don't need a control box
to work.

These are the correct ones, they are used on a lot of the TVR's for boots, tailgates and doors. Had exactly the same one on the Gredge for the last 14 years using just the 2 wire connector and the the make and break switch with no problems.

Does yours whirr then Chris before opening?

Mine definitely goes "clunk" so I think it's a solenoid (same on all 350's I've had too)

There seem to be too many wires to wire into the standard wedge harness - how would you wire that up?

Mine makes a little "Wurr"...I think you only need one plug as the other i should imaging locks..Remember..The Ford fiesta doesn't have a button push to open the boot...

Yep a little whirr then clunk!!!! Just need to use the 2 wire block the others are not needed on the Wedge

Both of mine "whirr and clunk". They look the same as the photo. 350i is wired independent of ignition and 390 is wired through the ignition.

Fair enough - I guess no-one holds on to the push button after the 'clunk' so it works out ok.

Does the push button just go to the two wires (= motor drive) ? If so, how does the unit reset itself when closing the boot ??

Just a proper good klunk from mine after door open, ign. on, Bryan Johnson screaming his lungs out for a second, ign. off the boot is open.

Hi Andy...It locks again when you push down on the boot lid like the 280i....

[RCK974X]

No - I meant that if it's a motor driven one, doesn't it 'stick' wherever it was when power taken off ? (because it's got gears and stuff in it).

or probably it doesn't work quite like I thought.....maybe it has a ratchet or something.

[adam quantrill]

I was thinking that too but maybe it gets pulled back by the spring in the lock.

Mine are all solenoid types and work immediately, and will get pulled back as soon as the button is released.

Mmm...Not sure mate but seeing as its been utilised by TVR then its probably open when its shut and shut when its open...

Don't know if this would do the job

Won't you have to reverse the motor to make it go the other way? Unless the lock spring is strong enough to pull it back.

Actually thinking about it perhaps it opens enough for the catch to pop out and closes again and then the catch is engaged with the lock with the closing of the boot lid?...

[Jack Valiant]

Its simple enough ..... the arm is fully open and under a small amount of tension in the off / locked / closed position. This is via the short bike cable. When you push the button the motor / arm retracts, the boot lock pops open. Release button / take finger off - the mechanism retracts under tension from the latch spring.
