does any one out there know if you can purchase a instrument voltage regulator for a sierra instrument cluster

 

thanks graham

The regulator is a standard electronics 78 series voltage reg at if I remember 10Volts.

It is in a TO220 package and is a 7810 available from RS and posibly CPC

I worked with electronics for 30 years some parts dont change and feel like they have been round since the arc was built.

Ian the 10v regulator appears to be a bit of a rare beast. I have managed to purchase a 12v one would this be ok to use. Am i right in assuming a 10v one is used to allow for a margin of saftey

thanks

The 12V one won't realy do because of the dropout voltage (don't go there). Use a 5V one with a 5V zenner diode in the centre leg. As Ian said, use a TO220 package and bolt it to a heatsink.

[Guest dark horse]

wont go that route then. Nice to know there is another way round the problem thanks for your help

Heavens sake guys, I am glad I work with the "Up" and "Downy" bits. You lads can keep your "Electrons".

Two attoms are walking down the street and one sais "I think I've lost an electron", The other one sais "are you sure?", the first one sais "I'm positive"
