A non-polarized and high impedance voltage divider/float circuit may be used as a diagnostic instrument. The circuit may permit a non-polarized DC connection and permit greater voltage spans when illuminating polarity indicating devices. The diagnostic instrument of the present invention may be non-biased (that is, it may be hooked up to the power supply in either direction), may allow testing systems of various voltages and may be capable of seeing signals of opposite polarities simultaneously.
