Recently, the topic of using an electric oil pressure gauge (to replace a
mechanical one) was discussed. Looking at a "sample" gauge wiring diagram in
the Holden Vintage & Classic catalog, it seems that they recommend placing
the electric oil pressure gauge at a 12v supply. This differs from the other
two electrical gauges (in a TR6 anyway) -- namely the water temp and fuel
level -- which are wired *after* the voltage stabilizer (and thus a ~10v
supply).
Does anyone know why the oil pressure gauge is treated differently from the
water temp and fuel level gauges? I'm quite curious (and admittedly know
nothing about how a electric oil pressure gauge works). Is it because the
oil pressure sender has the ability to make the same adjustment a voltage
stabilizer does for the other two gauges? (If so, this might explain the
relatively high cost of the oil pressure sender).
Thank in advance for any insights.
