Thought I'd post this here in case it helps others.
Hitch alarm on engcon ec206b wouldn't go off even though bucket was securely on and locked off.
There are two sensors one on the end of the pins that go through front jaw like below.

And a sensor that goes through back jaw that is accessed via a little plate on side of hitch.

In my case a stone must have been in the back jaw when I tried to lock off hitch and this stone had been crumbed and some shoved up the sensor pin hole, it had pushed sensor rod far enough away not to activate sensor when bucket pin was in position in the jaw, it can be repositioned from above behind the plate.
Simple when you know how,but not immediately obvious to spot when jaw has crud in.

tip of that proximity sensor has had a bollocking - should be flat ... got a similar set up on the Startrite band saw .. tells it to switch off at the bottom of the stroke ..... basically similar tech as yer average ABS sensor ... very fine wire coil wound round a magnetic core, 'cept this'll have its own power source as the pin's proximity would not generate any voltage, like the hall effect in an ABS sensor does

Glad you sussed it Kev :cool:

The main things to try and id, its the output type pnp or npn, and normally open or closed, then match the thread size and detection length up

aye I bet it will be ... if it comes in an Engcon packet ....
... I'd have it out sooner rather than later and look for some numbers, whilst they'm still hopefully visible -- it will be a generic part for sure :rolleyes: ... and probably a quarter of the possible cost
