Good morning and ASSISTANCE

Good morning I would like to introduce myself briefly. I am 26 and since the day before yesterday proud owner of a Suzuki Samurais ( 07/91, 130tkm, GKAT, 4WD, convertible, Japanese model, HardTop, Black, 235-tires, grey leather seats – otherwise minimal equipment BUT especially !! almost stainless !! what animated me to buy ) Have read here already a lot about the samurai 🙂 great forum – and pictures still follow here of course. The pride of the car held until this morning. Since I him yesterday first registered the car was standing around 2days and this morning it didn’t jump any more 🙁 A small clock in the amaturary board was still in operation (well, that doesn’t take so much – radio was definitely off because it was upgraded by me). Light I honestly didn’t test to my shame, because I wanted to work and took the other car. Prehistory : Before the test drive the car was short-circuited, then ran also almost 2 hours. I have the car several times and What can this be? Battery defective ? alternator? creep current? *snow* this is going well ….. Just a few questions : Unfortunately I have no BoardBook or TÜV report or other and am a little dependent on your help. I still need winter tyres or ATs, since the 235 are probably too much. Where do I get rims, which size should have been registered with me 195 + 20 5. The stand gas runs constant at 2300u/min – is that too much and if so, how do I adjust it optimally? Which additional tools and devices are useful in samurai? Thank you in advance Petz
