My battery gauge goes to the D side about 1/2 way and when I put the turn signals on ,you can see the battery needle go with the signal. Could this be a bad headlight switch? All gruonding seems good.

If so then the amp gauge will show a discharge any time something is turned on because there is no current being fed through it back to the battery.
Check your voltage at the battery with the engine running and headlights on. Should be around 13.5 volts to 14.5 volts. If so then the alternator is working.

Check the belt. It needs to be real tight as there is not much surface contact on the pulley with the 6 cyl. engine.
They say money can't buy happiness. It can buy old Chevy trucks though.

I needed an alternator with an internal SELF ENERGIZED REGULATOR .So now the truck has plenty of power and the battery stays fully charged.

But glad you got it charging. | | |
