300tdi clock replacement ideas?
I use a battery cut-off when parked for security and it does my nut in that the clock doesn't tell the correct time, so it's coming out Rolling Eyes

I can blank the hole, but maybe I could add a gauge - what would you do Question

Must be in-keeping style wise, but I'm thinking maybe revs or boost - needs to be not hard to install Laughing

Ideas please Thumbs Up Rob

Technically it is correct twice a day………. Whistle

That reminds me, my clock is still on British Winter Time. Almost not worth changing it now, judging by the weather here Laughing

I had a battery cut off on my 300tdi and i ran a low amp fused link between the terminals. It kept the clock, interior light, dash lights and stereo memory working but any attempt to start the car would blow the fuse.

Put a small fuse across the isolator, it will keep your clock going (and radio memory etc.) but will blow if someone tries to start the car.

Thanks for the suggestions. I left it isolated for 6 months last Winter and it started first turn, so quite like the idea of completely isolating as it avoided any battery issues

My 90 has been set up like that for nearly 20-yrs.
Small (fused) supply off perm live side of FIA isolator which serves alarm, tracking device, radio, clock, and an interior light. This feed is fused at source so any damage to the cable will blow the fuse (which is inches away from the FIA switch) but the remainder of the vehicle is isolated when switched off. ONE LIFE, GET IT!

I have took the clock out as it would not work to change the hour twice a year, not bad for the original one, so i got a boost gauge fitted Thumbs Up Clayton.

have a look at this, pay attention to the wiring Thumbs Up This is designed to keep the alarm features etc on line, but as soon as some Censored starts the car, that goes pop and the full works is dead in the water.

Well, after a year, unsurprisingly this issue has not gone away, so it's decision time!

I feel a blank looks a bit low rent, but the solution must be period correct, so I'm thinking a voltmeter or oil pressure gauge might just be a suitable replacement for the clock.

But, will it be difficult for a numpty to wire the voltmeter? Oil pressure gauge more difficult I assume??

I would prefer used, to be in keeping with the existing fuel gauge and water temperature so if anyone has anything please fell free to let me know.

Thumbs Up

Have you thought about trying the clock with a 9V battery? Fairly sure it would still work and the battery should last a decent amount of time.

As has already been suggested, just bridge the isolator switch with a small fuse, 3 or 5 amp should be plenty and will pop as soon as the heater plugs or starter motor are activated.

This will cover you for keeping the clock & radio active during day to day use (apart from when you keep forgetting to switch the isolator back on Rolling Eyes ) and just requires removal of the fuse for longer periods of inactivity such as winter lay-ups etc. Setting the clock in the spring after a long period is no real hardship?

Or.... if you didn't want to keep any of the other electronics live (alarm/interior lights etc), then run a +ve cable from the clock back down to the battery, add a fuse at the battery end and connect it directly to the +ve terminal of the battery (or the live side of the cut off switch)

That way when you turn the switch off then everything will be off apart from the clock.

But I feel it would be better to have the alarm live as well.
