i've had my prosport EVO oil temp and pressure gauges hooked up for about 10 months now, no problems.
Recently, my oil pressure gauge has been tanking to 0 at idle and when a high electrical load (turning fan on max) is applied.
hoping to solve the problem i rewired everything from my previous set up to connecting it to the IG2 fuse and grounding the gauges directly to the frame. that did not solve the problem, so i then re did the wires from the senders of both gauges, cleaned it up and re organized all the wires down below...
this also did not solve the problem
i find it hard to believe that it's a bad sender because the problem is only seen with high electric loads. The temp gauge is also sometimes affected (about a 5* rise in oil temp with blower on high)
any suggestions? things to check
i almost think this is a sign my alternator is in the first stages of taking a permanent vacation.
