I posted this a couple days ago but in the wrong forum. Have been having alternator trouble so I bought a brand new 200 amp one. I put it in and it would drift from a full charge and hover around 9.5 10.5 volts. So I sent it back and they said they "fixed" it. In the course if getting ready to install it I ran across a mechanic that said that the single wire that plugs into the voltage regulator on the back of the alternator should have some level of voltage showing all the time. It should be more when the key is on and less when it is off. On mine, when the key is off I have nothing showing and when the key is in the on positon - not running - I get a reading of 11 volts. Normal or not??? Battery is showing 12.2
Thanks

This is the third post on basically the same subject. I just moved your 2nd post OFF of LT1/LT4 Engine Tech, to "General......" Now you've posted it again, even after I moved it.

You're describing an electrical problem, not an "engine" problem..... PLEASE post once, and post on the correct forum. If you have new info to add, just keep adding to the original thread.
