Alternator?

[1979Jimmy]

Has my alternator gone? When i start my truck up the voltage gauge is sitting at about 10 and after a few miles its goes up to alittle over 13 volts. Is this normal?

I think that sounds about right. Mine does the opposite, it goes down really low. I've had it checked by a few different people and get the same reply...... "it's good". You gotta realize these guages are far from accurate most of the time. For a piece of mind take it to Autozone or whatever parts place and have them check it.

That jeep thing? Yah I understand it....... Like my Blazer? <a target="_blank" href=http://community.webshots.com/user/blazerk5>http://community.webshots.com/user/blazerk5</a>
