wired in the gauges from a calibra following a how 2 on cavweb.
When i connect the live lead and ground the needles on th oil move past maximum and the volts reads correctly.
When i connect the sidelight s they work fine, but after fitting a oil sender it has no affect on the gauge.
Even if i try to earth the oil sender lead it does not register any different.
Any advice greatly received, and they are brand new units.
Thanks in advance
