Instrument Cluster Rebuilding

Just went through my dash . I'm in the process of checking instruments now . One thing i did was get rid of the old voltage limiter and went solid state. You can by them on Ebay for about $20. or make your own for $5. Doing this will give you a constant 5v with no spikes. Go to allpar.com they have pictures and detail discription on how to make them and you can get everything at radio shack, I think it cost me about $4.80 for everything. Also check your grounds and at your gas tank.
