Agriline Instrument Panels

A word to the wise. The Fuel gauge and Temperature gauge on the Agriline replacement instrument panels for the 4600 are polarity sensitive.
The original instruments didn't care a jot as they (I think) are hot wire gauges. The ones in the panel supplied by Agriline will not work unless the correct side is connected. In fact they will try to deflect even more past zero ! My replacement arrived this morning and when I fitted it, the common lead from the regulator was already fitted to the two gauges but on the wrong side. A quick bench test with a current limited lab supply showed what the problem was and it was easily rectified.
(Panel changed as the elapsed time 'running hours' counter was totally missing when I got mine.)
