68 Barracuda........ Temp and Gas Gauge Issue.

I recommend the RTE because it emulates the pulsed output voltage of the original limiter, and thus keep the heat load minimized on the IVR. The big issue with using a standard regulator is that when the oil pressure is high, the tank is full, the temp is high, and the alternator is putting out 14 volts, then the heat load on the regulator is pushing into the 5 watt range. With no heat sink paste and a small heat sink like shown above, the junction temp is going to soar immediately well beyond 125*C and that is moving into eventual failure territory. The PO's 5v regulator obviously did not last based on the pix in post #1.
