88AMComanche Posted May 20, 2011 Posted May 20, 2011 I have the Sun Pro gauge set (Oil pressure/temp/Voltage) ......I hooked up my voltage gauge just fine & it usually reads between 11.5 and 13.5 depending on rpm or running or not. But I never disconnected it from the regular IN-DASH factory gauge, so I get volt reading from BOTH gauges & they Both read normal. Any opinions on this?? Id Like to disconnect the factory dash volt gauge but not exactly sure where or how and they both seem to operate just fine & both seem to be accurate. Is it ok like this?
Eagle Posted May 20, 2011 Posted May 20, 2011 Why would you want to disconnect the factory voltmeter?
88AMComanche Posted May 21, 2011 Author Posted May 21, 2011 I just wasnt sure if it will cause a problem long term having them both reading voltage. Why would you want to disconnect the factory voltmeter?
airspeed Posted May 21, 2011 Posted May 21, 2011 An electrical volt meter would be considered a passive device, requires no power. The electrical system doesn't even know that they are there. Your voltage when the engine is running should not drop below ~13V.
