I am embarassed to tell you that I went and purchased a mulit tester "actron" is the name of the one I got. I have read the instruction 3x and still have no idea of how to use it. It has a dial and around it, several sections. I think I want the one that says DCV, but what number do I set it to? It also has 3 holes to plug a red and black wire into. I know I can do this, Please don't give up on me. I will wait to hear back from you on how to use this silly thing.

OK, you'll want to put the red lead in the hole marked + and the black lead in the -. Set the dial to DCV to a number higher than 12, probably should be a setting for 20+/- DCV, that is the one you'll want. Before starting the car put the + lead on the + battery post and the - lead on the _ battery post, what is your reading? Should be 12.5vDC or so. Next start the car and repeat the test, what is the reading now? You should be seeing 13.8vDC or so.

Report back with your findings.
