72 overcharging

What battery are you running? I have the same high charging rate but I have the "red" Optima battery and was blaming the discrepancy from factory charging specs on the battery. I have already bypassed the amp gauge (converted to voltmeter on dash).

Satellite stock 318 results after warm-up (perf. viscous drive fan)
Charging Voltage at idle (headlights off) 14.5 Volts
Charging Voltage at idle (headlights on) 12.5 Volts

And I also have the headlight relay kit installed from member "Cracked Back".
