electric bear claw latches

I have electrically operated bear claw latches on my 40 Willys coupe, push a button and the latch opens. However, and this just happened today, I can't close the door cause the latch will not hold it closed. This happened to both doors and just happened today. I had taken the front end off cause I'm replacing the engine and the only wires I disconnected were the headlight/parking/signal lights and a ground wire. Replacing the ground wire does not make a difference. Any suggestions??

Bill

Can you close the doors all the way? Are the latches in the "open mouth" position when you go to close the door? Can you snap the latch closed by hand?

I think electric latches only trip the latch open. The latch is normally closed by the physical force of the peg striking the latch and then snapping it into the closed position. If the latch is in the open mouth position you should be able to snap it into the closed (locked) position by hand or by pushing the peg against it.

Possibly the switch is somehow always on...and thus as soon as you close the door, the latch automatically pops back open. Check this by simply using a screwdriver or other tool to push one of the latches shut. You should then be able to observe what is happening.

Bill,
Long story short; when you open the door, push the door release button for a full second.

I had the exact same problem on my Dad's '51 F1. The problem is the actuator.
Inside the actuator is a small electric motor, some gears and a clutch mechanism. On some actuators, the clutch stays engaged with the motor if power is removed before the actuator reaches the end of it's stroke. In which case the actuator is left still pulling on the latch release rod. You go to close the door and it bounces back open. The latch can't latch because the release lever is stuck in the pulled position.

If you make sure to push the button long enough for the actuator to make a full stroke, it will ensure that the latch release lever is returned to it's lock position and the latch will work properly. At least it did in my case.

Hope this helps.

Joe G

It appears to the the actuator itself. I took the panel off and observed the action of the actuator. It will pull down to open the door but it will not come back up, it stays in the downward position. I have to pull it up by hand. I've ordered a new actuator.

Thanks guys
Happy Holidays
Bill

Did you try Joe G's trick of keep the button depressed to recycle the actuator? Also, I was going to suggest unhooking the battery ground for about 10 seconds, then moving the actuator to the closed position, and then hooking the battery back up. Possibly just out of phase as I think Joe G is describing.

Worth a try even if you have a new one coming.
