Hi. Haven't lurked in awhile
The last time I spent some time on this forum was before I did the infamous np242 swap. That all went well, but now I'm back with a slightly different problem.
Specs: '93 ZJ, 230k'ish km on the clock, I6, AW4, np242. No real mods, but the battery is a optima redtop which is about 6 months old.
Last night as I was coming back from a pretty epic weekend of skiing, I noticed the voltage drop from the usual ~14 to somewhere just over 9. Uh oh. She seemed to be running okay, so I turned off most of the electronics, and found a spot to pull over. Pulled 'er over, popped the hood, checked the battery connections (which have been problematic recently), retightened 'em, etc. Unfortunately, when I restarted 'er (started no problem), the voltage stayed extremely low (~9.5, with no real variation), and the Check Engine light came on.
Got home okay, but unfortunately, this was all pretty late last night, and I had to come in to work this morning, so I haven't been able to pull any codes, or have a closer look under the hood. Just wondering if anyone has had similar issues, and any recommendations?
Alternator? Something else electrical?
Hopefully it's not a career ending injury, because I'm not living at home right now, and have limited tools and work space.
