hey folk, you’re all fit in the autoelectric field. therefore the following question to you: I connected the radio memory contact correctly with durationplus. Proof: Theft-led flashes even with the key taken off and if I turn on only ignition level 1 or 2, the storage is still available. however, as soon as I start the motor, the radio goes off. and when I turn on again, all storages are gone again. what can go wrong here? it can be because the battery already sees r old/weak? what solution is there? e.g. radiopower also at perdandplus? car: mazda 626 radio: the one from aldi thanks already
