problem charging

On my 87 K5 Blazer at idle it doesn't charge at higher RMPs it charges at about 14 to 16 volts.
I have a new red top optima and a new high amp Alt. What else could it be?

RE: problem charging

Is it a rebuilt alt ? maybe a bad voltage regulator.

RE: problem charging

You should not be getting voltage that high out of the alternator. It definitely sounds like the voltage regulator is bad.

RE: problem charging

I will take it in a get it tested. I think that it is rebuilt. I'm going to go through and redo the ground contections. Thanks

got it tested and the regulator failed. got a new one and truck running good. Thanks again!
