Insert the sensitivity switch through the faceplate with the three connection prongs positioned towards the battery drawer, slightly towards the centre of the reel. Tighten the nut. Fasten the sensitivity knob on the front of the switch using the brass screw. 17. Connect the black wire with quick-connect fitting to the negative terminal on the battery tray. Connect the red wire with quick-connect fitting to the positive terminal. 18. Connect the tape to the new circuit board assembly: a) If this is a Mk2 Water Level Meter, press down on the white terminals on the circuit board and insert the tape leads. Release the terminals and the leads should be secured. The lead on the bottom of the tape (numbers facing up) is inserted into the terminal with a white square below it on the circuit board. b) If this is an Mk1 Water Level Meter, with a Molex connector on the tape leads, remove the Molex connector by pushing out the two pins. Cut each pin in half (see image below for correct location). Use pliers to flatten the remainder of the pins against the tape lead, so it fits easily into the terminals on the circuit board. Connect each tape lead to the new circuit board assembly, as described above in step a. Note: To secure the battery tray, the #4 x 1/2” Phillips Screws are for plastic reels, while the #4-40 x 1/2” Phillips Bolts and Nuts are for metal reels. 9. Put the new Sonalert through the faceplate, and secure it using the retaining ring. Use the photo of the fully assembled faceplate below as a reference for its position. The negative terminal should be closest to the battery tray. Sonalert Sensitivity Switch Light Battery Tray Test Button 10.
