Whats up.... SOrry it took so long for me to get back to you. Anyways, my truck was fixed by changing the starter contacts. Yes, that is all. THey are very easy to just look at and see if that is your prob. Bout $85 and its back to new. I know better now, but I listened to the people that were saying the diode thing and all, the tests that they ran came out just like you have described with the low charge and all. Anyways I ended up getting a new alternator because the guy that looked at the diode charge said he was sure that was the prob, three days later my truck wouldn't start. Blah blah blah, took it somewhere else, and it was fixed in a couple hours. Hope this helps you out.
