Cluster voltage limiter

[bherman]

Hi Guys', I believe that my voltage limiter is not providing the required 5 volts for the gauges in my instrument cluster. Although I haven't taken it apart and checked the circuit, none of the gauges work leading me to suspect the limiter. Previously I read a post on this site that explained how to replace the voltage limiter with a solid state device. The post said that this modification also produced more stable gauge readings as the voltage did not fluctuate. I can't find the post. Does anyone know the name of this post or where it's located? Thanks Brian.

It was the thread on the DC Buck Amazon sells (that does not work). Here is a link to what I have done in the past and it works great:

Thanks very much Brian.

Just to add my two cents; I pried the case off the dash regulator and gutted the bimetal switch. Then I mounted the LM7805 onto the case cover of the old dash regulator and wired accordingly. Good luck!

I got mine from Classic included with the circuit board. The old board was toast with loose and broken pins. Was a no brainer.
