I'd need to do some research, but isn't the part on the dash basically an LM7810T regulator? It's a part you can get from digikey for pennies. I'll try and pull my instrument cluster tonight to take a peek, but I think this should be a direct-fit replacement (does anyone have a photo of the regulator installed on their cluster?) -----Original Message----- From: Vanagon Mailing List [mailto:vanagon@gerry.vanagon.com] On Behalf Of David Beierl Sent: Wednesday, December 08, 2010 11:09 AM To: vanagon@GERRY.VANAGON.COM Subject: Re: Voltage Stabilizer in Instrument Cluster At 12:49 PM 12/8/2010, Anthony Egeln wrote: > The upshot was that the voltage stabilizer should be replaceable with > any matching 10 volt part.
Trouble is 10 volt regulators aren't that thick on the ground, that not being a typical electronics supply voltage. However there are readily available adjustable ones like the LM317T (http://www.national.com/ds/LM/LM317.pdf ) where you set the output voltage with two resistors. These folks will sell you one for twenty one cents with a buck shipping (but they have a $5 minimum order) http://www.taydaelectronics.com/servlet/the-187/LM317T-LM317-Voltage-Regulator/Detail
.
So you can pay money for the real thing or work for the generic, your pick. I can tell you resistor values if you need them. You shouldn't need the capacitors shown in the sample circuit -- the gauges don't care about transients.
