I suspect the voltage stabilizer has died as the temp gauge has stopped working, & the fuel gauge has never worked properly (always reads 3/4 full regardless).
Would this be a dodgy voltage stabilizer?

I have the Nippon Seiki gauges but am unsure how to replace the voltage stabilizer.
Is this possible? How do I go about doing this?

Hi,

There's a post or 2 about this, I've posted in one about the replacement component required. 

Have a search it should show up...

Cheers  :proud:

Nice one.

 

As Maplins (as mentioned in the Link) are out of business, you can get the Regulator (assuming it's also 10V like the Smiths one) from RS Components;--

The 10 Volt types are a little obscure and not easy to come by.

 

I also note in the linked article the use of a heat sink. If it's onlt the Fuel and Temp gauges that are being run off this, I wouldn't bother with the heatsink, however, a couple of small Capacitors should be fitted too, one between the Input & Earth and the other between the Output and Earth, anything around 1 to 10 Microfarrds would be fine here, just be sure that have a 15 volt of higher rating and watch the polarity of them.

Hi,

Good find!

The one I posted in was linked to that how to post. The question was asked as Maplin had just closed.

I looked up a 10v 1amp voltage regulator on eBay for my reply.

Cheers  :proud:
