Jeep ZJ electronic spins

Hello together, I’m new here and therefore still a bit clumsy, but I can write at least :-D. So, I bought my first car about 1/2 years ago, a Jeep ZJ, 4.0 Laredo, bj.98′ When collecting and for another 3 months everything was fine with the car. When I left it for 2 weeks then the battery was empty, thanks to a good motor that started quickly I could then charge the battery again without a charger. Since then the battery is another 2 times lee r. That’s only when I didn’t drive it for more than 1 week. So I assumed something wasn’t going to work, but I didn’t have the time and not the necessary tool to measure the currents. If you want to say something about it/further information–> goes to point no. 6. But now in the last month, funny, illogical things have always happened, which have to be attributed to a problem of electronics/electrics. I list these all times: 1. Starter engine does not get genu g current, I had trouble, because engine to start after I drove about 1h. It seemed as if the battery was empty, but this could charge for an hour… the generator works according to voltage meter on my dashboard. As the engine ran again we drove again about 10min, took a short break and then worked again perfectly. 2. Transmission does not switch correctly, has happened to me so far only once, possibly user-error… engine started, gearbox in D ges the engine is almost soaked off… speed down to approx. 500 rpm and has stopped, so I got off the brake, got on gas and that was everything, the rest of the ride went normal and without problems… 3. Light switch does not switch correctly, smallness but still a bit question-würdi g, the Cherokee has a rotary switch, which can be changed between off-standing light – dipped-beam. So if I switch from stand-on to dipped-beam in the evening, and if I want to switch off the light on arrival and exit the car, I have to switch back to the stand-on before the off, the function also works, I switch off from there, but the headlights go on again…??hää? Speak the light, although the switch is off… if I still have to turn off… On a stand-off and again on a turn off, they finally go out… 4. Mileage suddenly, even the little one, once I noticed that the indicator for the mileage became weaker and weaker, until this completely out true…I drove on, because the indicator is not particularly important to me during the ride. The next time start the light then went again. 5. The interior lights go underground long, sometimes the lights go nac 6. After I was allowed to borrow a measuring device for the current from the store, I took off all the fuses as well as the total consumption, result: no current except the one fuse for the stationary heating and the alarm system, together these 30mAh… the next day for the antenna from the radio no more… the fuse from the radio I have removed to measure, I say close I don’t understand… so nothing at all, like if the speakers don’t get any current…grobly said nothing else except the radio’s display..I guess, however, that I have to adjust something with it again, and not that the electronics is doing something wrong… 7. Here I keep myself short, thank you for taking the time to read all the 7th points. Thanks a lot. e for your help. Friendly greetings Liam 😀
