When I first start the truck I noticed that it was not charging enough. It would read between 10 &amp; 12volts. As the ruck ran abit (under 1 min.) the guage would go up to normal charging. The headlights would confirm for me by getting brighter that the reading was correct. Is this normal,if not any ideas?<br> Thanks

 

That is normal. The low charging is caused by the intake manifold warming grid. This grid kicks on and off until the intake manifold reaches a certain temperature.

 

Yea my 24v is the same. I was told that is normal and not to worry. <br><br>Bob

 

Your intake grid heaters come on below (I think) 50 degrees. They'll cycle for 3 minutes or until you exceed 18-20 MPH. They have a pretty high draw, which you'll see in the voltmeter and vehicle lights. This is completely normal and you should only worry if it's cold and you DON'T get the cycling.<br><br>As your batteries get older, you'll even get a check engine light as the initial draw brings them down below 10 volts. Mine are getting to the point where I'm going to have to start looking for new ones. 5 years isn't too bad though!

 

Thanks for the help, I feel much better now. My usual reaction would be to get another alternator or something, but due to the knowledge of the people here I haven't wasted money.....more for Bombing ;D
