Perhaps.<br /><br />Could also be the power supplied to the guage console drops causing the issue. <br /><br />Run a temporary test pair of wires from the battery directly. Check for a voltage drop ( any differential) from the know 12v pos to the supplied at guage(s) 12 pos. Then again at the known to be 12v neg to the supplied ground(s)<br /><br />Shouldn't be too had with a digital VOM to find a culprit.
It's obviously caused by a voltage drop but I would think your alternator/charging system would keep up with the drain. Do the gauges recover or do they stay back?<br /><br />c/6<br /><br />Hooty
