I would suggest that you try this:<br>

Would it have any effect? To put it crudely, but in the language that I can understand, wouldn’t the fluctuations still come down the Green/Black wire from the sender unit and hit the gauge’s terminal T? And wouldn’t those fluctuations still register as such on the gauge, totally unaffected by the capacitor? <o:p></o:p></p><p class="MsoNormal">Shouldn’t the capacitor be wired in such a fashion that the fluctuations cannot bypass it?<o:p></o:p></p><p class="MsoNormal">Maybe I’m over complicating things and should just try it without understanding it.
