Re: Help a 147 newbie diagnose some niggles
The pin holding the clutch pedal on broke on my 147, and when the pedal twanged up, it pushed the cruise control switch plunger too far into the body of the switch, stopping the cruise control from working.
I fiddled around, and found that leaving the switch open circuit, or removing the switch and shorting the connections together wouldn't cure the problem. After much head scratching, I realised that the computer will not activate the cruise control unless it has seen the switch in both positions, i.e. open circuit AND closed circuit.
So first ensure that the switch is actually working, and will go closed circuit when you press it, and open circuit when the plunger is extended. (I think that's the correct way around)
Then, start the car, get into the footwell, and press the clutch switch several times, then unplug the switch.
Now the cruise control should work normally, BUT it won't switch off when you use the clutch.
If all is well, and the plunger's too short to hit the pedal remove the switch and extend the plunger by your chosen method.
I took a piece of plastic and a soldering iron, and plastic welded it onto the end of the plunger until it was long enough.
The switch is secured to the plate by a bayonet type mount, so to remove it, rotate it 90 degrees anti-clockwise.
