hi,
crossflow with facet pump.the pump is wired through the master switch and into a three position switch, which allows prime, run, and off. the run supply is then run to an oil pressure switch. i think this switch is possibly the cause of a long term headache. i will rig up a test light to check the switch but wondered if anyone else uses this set up , and where i can get an oil pressure switch.
any advice welcome.
barry.
