Volt meter slow to normal

After starting my truck the volt meter now takes 40 seconds to raise to 13 volts. TIA!

Is it only on cold start? If so glow plugs are engaging.

Yep, glow plugs are still on. Depending on oil temperature, they can stay on as long as 2 minutes.

No. I disconnected all wire from the GPR and started the truck, no difference. As a matter a fact the voltage drops so low I get a CEL and the truck missfires until the voltage comes to 13 volts. I put a NEW alternator on, tested the batteries. No CEL yet but the Volt Meter still seems to take more time than usual to get to 13 volts. I'll go with this for a while.

I'd check with a VOM instead of relying on the gauge
