1992 corvette tach reads "0", fuel gauge reads "0"
1992 Corvette c4 electronic ignition, tach reads "0", fuel gauge reads "0"; The charging system is intermittent since a voltmeter on the battery will read 12v, and sometimes 14.5v. The alt tested good, and the dash voltmeter reads when a voltage is applied to it. Where is the tach filter located and how can I test it? What is the wire path from the dash to the point the voltmeter gets its voltage?
