I bought my 98 Wrangler Sport a few months ago, and so far have replaced the exhaust manifold, brake pads, front rotors, steering damper, crankshaft position sensor, spark plugs, and I think that's about it. I just want to get this thing tip top for the winter, but at this rate, I'm not sure it will ever be reliable.
So this is the newest development: I'm driving and the battery voltage indicator flat lines accompanied by the "check gauges" light. I get home before turning off the car. Start it back up and it seems to be fine, only now the voltage is at 12v when before it was at 14v. A few days later, I drive it around and the voltage meter keeps going off and on. I get home park it, come back later and to investigate. I remove battery terminals, clean everything with baking soda, rehydrate the battery cells, and start her back up. Now it's not turning over so well. Eventually the car is dead. I jump it, and it has a strange time starting. I have to give it a little gas while holding the ignition, but now if the RPMs drop in neutral it will stall. I finally, get it started and get it to my mechanic to park for Monday without it stalling out. The mechanic is just around the corner luckily.
So to recap, the current symptoms are:
-unpredictable battery voltage indicator
-radio flickering and going crazy
-engine stalls without gas
-seems battery isn't charging either
So is this merely a bad alternator? The engine sounds sketchy when running, like the pitch of its sound goes up and down.
