Hi, i've got a wired problem i don't find the battery. .. the second battery. I found out that all the electronic still works even if i disconnect the battery behind the front fender on the drivers side. So there must be another battery but where. I looked nearly everywhere.. and because i still mount parts to the car many areas are open and visible like the engine bay without engine. So i can say that there is no battery in the engine bay. Also in the front compartment nothing. Then inside the car i got the seats out and the carpet away. There is no battery under nor behind the seats. Then i looked behind the radio nothing. I even robbed deep into the passangers footwell ... i don't ever thought that there is sooo much room behind the footrest and fuse box So where is it??? I don't want two batterys in the car also if its a normal battery maybe it starts to leak acid everywhere.
I know you said you looked in the engine bay, but did you look behind the left rear wheel well, the old location for the early cars? If it isn't there, then try opening up the trunk and looking under the trunk liner. You could take out the window washer fluid container and have room to put in a small battery. Just a guess?
I dont have any wheelwells installed. Also i don't have anything except the abs / brake system mounted in the front. I can look to naked matel in front and rear. Only inside the cockpit, pedals .. are mounted. I don't looked unter the car in the middle tunnel , i also don't know if there is some space behind the tank? Or space behind the pedals..or behind the dash? Or where the steering goes through?
Did you actually physically disconnect one of the terminals from the battery, or just turn a disconnect switch?
Yes both connectors from the battery. The second battery only works when i open the door or turn on the ignition or something i don't figuered it out. When i go to the car on a new day start the radio and disconnect the battery radio shuts down. When i go in and turn on ignition then it works then i can disconnect the battery and the radio still works. Maybe it only charges the battery when the doorcontact is open or i turn on the ignition and because the second battery is old or small it discarge itself over night. I dont know i only know that i got 12V when i put my primary battery out on the table and that is not normal When i first noticed it i won't believe my ears disconnected the + connector on the battery radio keeps playing then i thought ok big capacitor anywhere waiting 3..6...7 seconds .. mmm calculated fall off time on only 2A .. no cant be a capacitor or the capacitor must be bigger then the tank... then i searched for the second battery and surrendered after some hours. And i found out that it is connected with the power switch on the front when i turn it off there the radio and anything else stops.
The 348 stores the battery in the front left (or back left for early models)...the 355 stores the battery in the front right. I'd look there.
No both sides no battery i have the frontbumper off. Behind the pedals is there the same big room like on the passanger side? It doesn't look so .. But it must be anywhere ... last chance would be to follow every cable on the emergancy switch. But the cables are all tied together and go round the hole car.
Is it perhaps a 4 post battery and they've got cables in the back side of it (so when you take off the top cables, it's still powering the car)?
Okay you said you looked behind the radio. Does that mean that you took out the climate control pannel and looked behind it? If not, try that.
Yeah, if you took out the mouse motor ECU's (maybe there are none for the Euro 348's?) there would be room down under there.
I have a normal battery and put the battery out of the car 5 meters away from it So if my battery doesn't develope wireless current then it got the current from another battery. I have the climatic control out. Also the entire center console. I haven't looked under the car , behind the tank, behind the padels, behind the dashboard. But i don't know if there is anywhere some sace for a battery. Mouse system? No in europe they had normal seatbelts. Where they mount the motors? And under the car in the middle there is a plate with a sealing for what is it? The plate wich covers the shiftcables, gascable, climate pipes ... The rubber sealing like a doorsealing is also formed like a battery ... but it seems tobe stock because it is also in the partbook.
I'll bet on an alarm system being installed, having its own power source (battery) and energizing the car through the ingition circuit. If you have an alarm it may have a battery so that it still works when the regular car battery is out. If so, then disconnect, or remove the alarm system from your car. They have been known to cause all sorts of bad electrical things to happen that are otherwise unexplainable. BT
I think BT has nailed it - it sounds exactly like an aftermarket alarm system. It would have a battery pack to engage the alarm if a thief disconnected the battery. You are probably looking for something about the size of a cigarette pack - and it is probably well hidden so a would-be car thief can't easily find it and disconnect it.
No alarm system connected. Also i can hear radio with the second unkown battary atleast 30-60min. till now i dont test how long it last only with the second battery.But maybe he removed the alarm system and not the akku pack or battery. I think i have to remove the complete dash , pedals to find it. Maybe the tank too.
Well heck, as crazy as it may sound, have you looked inside the doors, behind the pannels? You could fit a small battery in there. Or even in the glove compartment?
Can you use one of those electrical tracers for a DC circuit? You know, where you put one thingy on the electrical item, and then use a probe to find the active circuit? Maybe you could trace it from the fuse block using one of those thingys. You know, like for testing circuit breakers and Christmas lights? BT
This is sounding nuts sammy. I reckon.............leave the 'normal' battery out and if you still have power, start pulling fuses and relays one at a time and see what that does. You may kill the power source and then maybe identify which circuit it is wired into. Will the car start by any chance with the '2nd' battery?
Because i repainted the car and doing other intense works on the car i nearly looked everywhere because all is apart. Inside the doors is nothing. I only found out that the second power source is also connected to the main switch ... but there are so many cables. And it is nothing stock that ferrari build anywhere inside a small battery because it is wired to the power switch and all cables look genuine? Ok could be done professional that it all looks good. I can't start the engine because the engine is still under development Drysumppump system, engine mounts and inlet manifold are still under construction if its all done i can test it but i dont think it can start the engine. Because then it must be a big part and because i looked on many locations it has to be something smaller wich fits behind the parts i doesn't have apart.
Something like a small lithium battery of some sort? But why???????????? Strange this problem. Very strange. Have you tried pulling fuses/relays yet mate?
