Voltage Gauge Drop
hey everyone, i have a 2004 ram 3500 cummins that was over charging at about 15.1 volts, so i installed an external regulator properly grounded to the alternator, wires to keyed power and soo on. It works great putting out 14.7volts, my problem now is when i get about 30mins down the road the voltage gauge on the dash goes all the way down to 0 (or 8 if you prefer) but using a multimeter at the batterys while the trucks running it still shows 14.7volts. Once i turn the truck off and starting it again after an hour or soo the gauge will work perfectly and drop out again after 30mins... Please help and thank you in advance

The stock wiring is disconnected from the plug, the plug from the alternator goes directly to the external VR. And when the voltage gauge shows nothing the alternator is putting out 14.7v

Not familiar with how the system is supposed to work on the newer trucks.
