Alternator and battery showing 14.1 volts with multi meter when cold or at normal operating temperatures. DIC shows 14.1 on startup and drops to 13.5-13.7 volts as engine warms up. Anyone encounter this problem and did you find the answer.
Voltmeter and DIC will always show lower voltage than battery…voltage comes from Ignition 1 circuit of IP so it will go through some circuits before getting there…on C5’s the same way…about .4 volts lower as you can see below…there will be some voltage drop along the way between the battery and IPC.
Dic not showing incorrect voltage
