    109A Alternator Upgrade Problems

    Been driving around to trouble shoot (what better way) and was able to get to work today ~15 mins and back. Right when I pulled into my drive way my radio turned off, my idle RPMs spiked to 1500. Turned it off and tried to restart it; nothing. Click. Would love some advice from anyone who knows...

    109A Alternator Upgrade Problems

    Alright; I found that the alternator was bad so got a new one in and installed it. Jeep fires right up but with both of my batteries will not charge above 9V with the alternator. The thing is the alternator is pushing power to the rest of the Jeep, and with all accessories on (light, air...

    1990 Jeep YJ "The Grey"

    All; Tearing apart the wiring harness when waiting for the alternator to come in and was met with just absolute chaos. Found about 20 dead end wires. Makes sense with the removal of the ECU and nutter bypass, but very frustrating none the less. Below is a picture of the nonsense. Made it my...

    109A Alternator Upgrade Problems

    All, Swapped a 59A to 109A alternator today. In theory should charge much quicker. The problem is that it is barely charging at all; and today I lost power when driving and had to do a quick battery change to get home. I brought an extra battery out cause I thought something like that would...

    1990 Jeep YJ "The Grey"

    All; Bought my Jeep YJ back in January of 2019 and have done quite a bit of work to it up to this point. I'll try to remember it all and explain it below. Keeping this thread running and open as I continue to make changes and additions to the YJ. Bought the Jeep, these were the details...

    92 YJ 4.0 revs to 2000 RPM, stars sputtering, and won't go any higher

    You didn't have any problems before doing the tune up? Are there any other symptoms? If it was running fine before I'd start with the things you messed with in the engine before going elsewhere. 1) check the spark in each plug. You can do this easily by turning the Jeep on, letting it settle...

    A YJ with an LS on Coilovers & Spidertrax Axles

    Definitely going to be keeping a close eye on this one. Excited to see the process you take to get that engine mounted. Looks great so far!

    Erik from Cali

    Hello all How I got my Jeep YJ is one of brash decisions, money burning a hole in my pocket, and a friend egging me on. Long story short, I set a budget last January for a vehicle I could off road with, work on, and make mine. I stumbled upon a $6500 neglected, beautiful IL6 4.2L that, when...
