Stowe Navigator 1

[julieros]

I have a Nav 1 with an intermittent fault which I am sure I can fix if only I could take the cover off the unit. Having loosened all the obvious screws I find that the unit will come apart once I have removed the knob from the rotary switch projecting from the front panel.This knob will not pull off with the sort of persuasion I can apply by hand. Am I too weak or is there a special technique or tool I need to apply?

Should just pull apart as a complete lump from the inside, if there is a nut under the knob then take that off too as the switch is mounted on the PCB, which is in turn mounted on the rear case.

I can email you the manual if you haven't got it.( Send me a PM - private message from my profile). Contains a wiring diagram but not a diagram of construction so can't help on that point.

Thanks for your reply. Are you saying that the knob should just pull off? I have tried using my fingers but it won't budge. Have you any suggestions about a suitable tool?
How about a Mole wrench?
