If you don't change to LED (and IMHO it isn't necessary) at least replace all the bulbs so you don't have to take the binnacle out again anytime soon.

Regarding the alternator not charging, I went back in to make sure I had the correct bulb as the ones I had on hand where for the door lights, differnt part number, so I stopped and bought the 161 put it in and the battery light still comes on and no charging. Is there any thing else I can check that might cause the alternator to not charge? I have had a couple of brief indications of charging but that is all.

If the belt is spinning the alternator and the light is on, it's time to take the alternator to a shop to get it rebuilt.

The alternator is/was new when I put the motor in, I checked the voltage at the brown /yellow wire with key on,not running and with the wire connected to the alternator I read about 1.2 volts, I unhook the wire form the alternator and it goes to what the battery voltage is at, 12 volts plus minus depending on how long since I charged it. I do seem to have something drawing juice when the car is off. I am going to disconnect the battery tonight to see if battery holds charge or if the battery is bad. Brand new a month ago.
If the battery is bad, but good enough to start the engine after a charge, the light should still go out and the alternator should raise it to 13.5V or more. So, I'm with David -- Pull the alternator and get it tested/repaired.

Well back to the alternator again. Well pulled it out and decided to try it on the bench, put it the vise, hooked the multi meter up to the out put post and ground to the vise. Took my portable battery jumper hooked up ground to the vise, and with a nail in the positive applied to the differnet terminals in the plug in area. (there are 4 prongs) no description on the alternator for the prongs. And with me turning the pulley with a impact would find the terminal that would "engage" the alternator and put out around 14 volts. Install in car and nothing.
Assuming you also put the battery jumper's positive wire on the main alternator terminal since it put out... If so, it should work on the car if your small brown with yellow trace wire measures 12V (disconnected) and you put it on the same terminal that you put the nail on to make it output ~14V. (The others in the socket are not needed.)
Be careful -- Those regulators are not very forgiving if you apply ground or power to the wrong one...
Are auto parts tests unavailable there?
Post a pic or two of the alternator?

Not really a definitive way to bench test the alternator. You really should put a load on it. You could have bad diodes or a faulty regulator. If the alternator does test good you could have a wiring problem and/or a bad battery. Get the alternator properly bench tested and have the battery checked. If they are both good you have a wiring problem in the car.
