Any thoughts on the following?
My gas gauge has always read high, my temp gauge seems to be reading higher in the cold weather than it did in the summer my oil pressure gauge is nearly pegged whether the engine is hot or cold (it only drops slightly at idle), and my voltmeter has always read 16-17 volts since I bought it in May. Could the excessive voltage be causing the other gauges to read high, or are they just crummy gauges?
