Nice Thanks. That will not be for awhile it would seems. Lee. I am beginning to think I may have jumped in to soon. And the reason I say that is because I have to burden you with things I should already know. And what makes it a bitch is the little time I have available to go and read up on everything. There is no doubt that I want to learn, And I may be a bit slow but learn I will in time. So what is your take on helping me? It has to be somewhat of a burden on you to help someone as green as I am. If you want to call it off until I have time to learn a bit more so to help in the process Let me know ok? I don't want to burden anyone.

Larry - if Phoenix can put up with me you're a piece of cake. Trust me!
Thanks Nav, I just feel kinda bad causing extra work. It's not like they are getting paid. But then again I am sure they will be rewarded down the road for the good deeds. I should have done some reading and got a little of the basics out of the way. I jumped in to soon!
Some put their toe in the water and others just jump in. Jumping in is OK - it just takes a bit to get calibrated. Make sure those caps aren't loaded and try not to let the smoke out - you'll eventually get there.

Take a pic of the component that is giving you those 1600 readings.
