Truck is starting harder
Recently my truck is turning over slower. It has been anywhere from 40 to 70 when this has occurred. It doesn't seem to matter if it has been sitting for a day or two or short time (it may be a little worse after sitting for a day or two). It has been puffing a little more white smoke when it starts.
My batteries read 12.29 volts after sitting for a day. and 12.9 volts after running for a couple minutes. I separated the batteries and they both stayed around 12.8 (truck off).
Does the voltage sound okay?
Is this a sign of the starter getting weak?
Thank you for any help.
I replaced the glow plugs 6 months ago and put on a Stancor relay
