Super A -Alt Amps

A while ago I had to rev the engine up as far as it would go to get the alt to kick in. When I did this it would peg all the way over past 20 amps change and then slowly work back down to 4 or 5 amps charge.

I decided I didnt like this so I took the alt off and had a smaller pulley put on and a little bigger gap on the pulley where the belt would fit down in there better. Got it back on and now the alt kicks in right off and charges at about 4 amps no matter the throttle.

Today when I brought it inside I turned the lights on and looked at the amp meter and it showed a discharge of about 4 amps. Turned the lights off and it kicked back to charge. I did that a few times and then I thought it shouldnt do that cause it would eventually discharge the battery if the lights were on for a long time. I did rev it back up for a little while but it didnt change anything, might not have let it rev up long enough.

I didnt drive it or let it run very long to check it out any more.

Does the discharge sound right?

I checked the belt this morning and it appeared tight but I went ahead and tightened it some more. I could tell it sat down in the pulley more after I had done that. So I started it and bingo it did just what it was suppose to do. I know I made sure last night it wasnt slipping but I guess it was such a small slip I couldnt tell.

I was so upset last night I had allready started pricing new ones. lol Now if I can just solve the rest of my problems that easy.

Thanks guys.

Before I had the smaller pulley put on I was getting a higher charge. The Alt shop that put the pulley on checked it out to make sure it was a one wire but I dont know if they checked anything else, I didnt ask them too cause it all worked. Just dont see how changing the pulley could have messed anything up.

I dont have anything to check it with so Ill have to take it somewhere if it aint working right.
