Fixed the Clock, But what’s this?

Postby Midnight.R » 11 Apr 2006, 17:55

My time clock has been making some bad grinding sounds recently and its been quite annoying so after fighting with the dash I thought I would give the clocks a good seeing to.

Turns out the spring clip holding the top half of the gears in place was broken causing one of the gears to roll around in the casing a nice simple fix.

Anyway on the water and temperature gauge one of the contacts has split and burnt in half. Strange thing is I’m sure both gauges work before I took them out but I have a feeling its for the lights since I don’t remember them working.

Oh and does anyone have one of those gear displays instead of the clock and do they light up depending on which gear?

I guess that would be expensive but what do they do?

Welcome to the world of chevettes, cheap and cheerful.

However, I like your idea. What you could do is take your gearlever apart, and fit a set of microswitches in the appropriate positions when the lever is in each gear, tie these into something like a TL084 op amp or a small optoisolator - actually stuff that, it's just LEDs so the switches should handle 30mA. Fit LEDs into the gear pattern indicator, then wire each switch directly to it. Easy enough job, the only problem would be getting the clearances right to actuate the switches. Probably put a switch on the common ground for when you've had enough of them.

On the plus side Mk1 astra's definitely used to have the same clock and presumably lots of other Vauxhalls too so there should be some decent spare ones out there somewhere :)

Mine works just fine and keeps good time, but unfortunately the adjusting wheel on the front is broken off, which means changing the time with the aid of a pair of pointy nosed pliers!

If you can get at it with pointy pliers, can't you glue a bit of dowel or similar onto it?
