I could really use some help.
Some backstory: For about 6 months, I've faced some very intermittent battery issues. Or at least that's what I assume. Everything would be fine then one day I'd have trouble starting the Jeep but with some charging of the battery, it started right up. I didn't worry too much because it was extremely intermittent. A few weeks ago, my wife and I left town for about a week. During this time the Jeep sat not hooked up to a battery charger or anything. When we got back, I got in the Jeep and it fired right up no problem. I drove it to drop it off at a mechanic who was building me a roof rack. He had it for about a week. When I went to pick it up, he mentioned to me I had some sort of electrical/battery issue. I trust this guy and he isn't a random mechanic I picked. He told me he had to jump the jeep almost every time he started it while he had it. He explained I probably have a parasitic draw and showed me how to chase it down.
I then began chasing the parasitic draw I thought I had. I used my multimeter set to 10 DC Amps and undid the negative terminal and began testing fuses. The draw I originally had before testing fuses was 0.13 amps (130 mA). I got no results on anything except fuse 20 in the PDC (1999 Jeep Wrangler Sahara 4.0). I noticed when I pulled out fuse 20 the current dropped to 0.001. So I researched and found that fuse powers several things like radio, interior lamps, and the OBD II port. I found when I removed C108 from the 100 pin connector driver side, it was the same result as pulling fuse 20. I tried this on all pins under there to make sure it was narrowed down to that one. I then began testing wires on that connector (Blue) and go nothing. I went to set up my multimeter in a way where I could see it from the windshield while working under the dash and every time I had it set up and walked around to the start testing wires, the amps had dropped from 0.13 to 0.001. So I went back and re-connected the multimeter and got the 0.13 amps and I held it there and after about 15-20 seconds it dropped to 0.001.
I also in the middle of all this went and had my battery tested and realized after 10 years it was shot. So I opened the wallet for a NorthStar AGM. I notice that when I test the alternator on both batteries I was only getting about 13.6 volts which is lower than I'd want but still acceptable. I don't THINK my alternator is quite in need of replacement.
Anyway....all that to say/ask: Do I actually have a parasitic draw or is the 0.13 Amp and eventual drop 0.001 a non-issue? And is my alternator okay? (I've tried to bold the key information above to help out...sorry for the long post.)
