Volts Regulator

[Guest ih007]

Is this bodge on my volts regulator ok? I ask because my fuel and temp gauges are totally unstable, and it makes me think the voltage they're getting isn't regulated. I couldnt get any power to them at all without soldering on that little green jumper wire.

[Guest elgey7]

I can't make it out.

If you can get me a clearer/closure image I may be able to help?

Hows this?

[Guest ih007]

Still not great is it but better.

There are components on the other side of that board...but you have already answered your own question...

Why not just goto a scrappy?

There was a thread on here a couple of days back about using voltage regulators from maplin. Go here to see it.

Mine has a 7809 1Amp voltage regulator IC, It has 3 rather delicate legs which need soldering to. 12V in, Earth and 9V out. It is bolted to a piece of copper which serves as a heatsink and wrapped up in some insulating tape, mainly to stop the wires moving around and breaking the legs. (I should have made up a small circuit board).the centre pin is earth and the body of the IC is not insulated so the heatsink is also at earth potential. Size approx 2x1x0.4 ins.

78 & 79 are 3 terminal pos & neg voltage regulator series

 

7809 = 9v positive voltage regulator.

7805 = 5v pos version.

7812 = 12v pos version

etc.

 

7905 = 5v neg version

7912 = 12v neg version

etc

 

the LM317 refered to in the other thread is an adjustable voltage regulator

with the votage output adjusted & set by a resistor combination across it.

 

If I could see the component side I may be able to help you.

Although as I said to the guys in the other thread the older 2 terminal

devices were crude but much simpler to use.

OK cheers guys,

 

I think i'll head for the scrappy and try to get a two pin regulator because i have two 3 pins and cant get either of them to work.

 

What year did the 2 pin go up to?
