Recently installed a smiths oil temp gauge and sender in the 64 bus and temp on gauge showing 130 - 140 degrees under normal driving conditions when actual temp measured with temp gun 70 - 80 degs.
Rang smiths and they told me their gauges are designed to work with 10volt supply only, therefore my system being 12v (13.6v when running) is the reason for temp showing high.
Anyone heard or know of this? Cannot understand as why would you make an automotive gauge to work on 10v when all cars use 12v system?
