Battery/Volt Guage
I got a question, When I start my truck the batt/volt guage will got to about 10 then rise slowly to about 14 stay there for a second or two and then drop back down to about 10. It will do this a few times then instead of dropping to 10 it will drop to about 12, it will do this a few times. As the guage dropps all the lights dim. After a few min usally after I have waited a few min then drive a couple of blocks then it will go up to the 14 mark and stay there and never drop again. I just started noticing it but it happens every time I start the truck. Today I drove about 20 miles in rush hour so the truck was running for about 45 min got to my destination was there for about 10 min and left again. When I started it up it all happened again so I don't think it has to do with being hot or cold since I know the engine could not have dropped that much in temp in that short of time however it is only in the single digit temps around here. My question is this normal? Is it the alternator? What should I check?
My truck is 92, 3/4 ton, CTD, manual trans.
Thanks in advance for any help anyone can provide.
