Copied from shoutbox to help anyone who needs to change the connector block in an actuator:
@barney115
The Clear Block inside on the actuator arm where the 4 core cable goes into the tiny screws are not in good shape 2 or 3 of them wont loosen or tighten.
@moonbase
Those screws are a right bitch, they got some odd variation of a phillips head and strip like a whore.
The connector block is easy to replace.
@butchyboy
Take a picture of the wiring on the block,then replace with a new connector block
Any of the wee electric blocks will do,you can get them in different sizes,any good hardware/etrical place will havem there only a wee few pence
@moonbase
Connector blocks have an amp rating, actuator might draw 8 amp briefly at start of movement, 10 amp block fits but tight, 5 amp block fits OK
The connector blocks I have seen in Jaeger motors and Superjacks have generally been under rating
