Hey y'all. I currently own my second CJ. The newest I bought 3 weeks ago. I know battery drainage is a common problem in the CJs and both that I own/ed have had this issue. Wondering if there is a common issue that causes this or does it vary greatly from one jeep to the next? Thanks
With key off, remove neg batt cable, and put clamp on cable end, and probe on battery neg post. Light will be lit if you have a drain. If light is on, start unplugging fuses one at a time, and when the light goes out, you've found the particular circuit your drain is on. If you pull all fuses and still have a drain, try unhooking your alternator and see if it goes out. My drain was a bad diode in the alterntor that was draining the battery.
