Blaupunkt flattening battery

Hi I have an Alfa 166 3 litre,2000 yr with a factory installed Blaupunkt cassette, cd changer radio in the Integrated Control System centre console. Should we not use the car for a week, with the radio and ignition off, the battery is flattened and the Alpha dealer states the radio leaking current and flattening the battery. Nobody seems to know in NZ how to fix this as they need software codes. Any help would be greatly appreciated, John

Hi,
I would be concerned about the amount of current required to kill a car battery in a week:

Let's assume that 1 week = 24 * 7 = 168 Hrs

A typical, healthy car battery will deliver anywhere between,
45 to 70 Ampere-hours at small currents, depending on the
size of the car (check your car owners manual)

Assuming a weak battery has a 40 Ampere-hour reserve, it would require an average current of 250 milliamperes to drain
in a week, or about 3 watts of power.

While this does not seem like a lot, it certainly indicates
something is wrong, because the clock and station memory
in a radio should take a lot less than that.

====

The first step is to make sure that the radio is actually at fault,
not damaged wiring or another one of the dozens of electronic
systems in a modern automobile.

Don't trust your mechanic on this, I have never met a gear-head
that was any good in electronics, but they do come up with
some fairly captivating fish-stories when they do not
understand something. :)

1) The first step is to disconnect the radio and isolate the
problem.

2) Remove the radio and hook it up to a 12V DC supply,
or battery through a digital milliamp-meter. Check the
current with the radio shut off.

3) Anything over about 10 mA or so is BAD.

4) If the radio draws any significant current with the switch
shut off, look for a bad switch or a leaky capacitor on the
B+ wire (before the switch, so it should not be hard to find)

Another possibility is the clock/keep alive controller chip,
but this is less likely. The most likely culprit is probably
an old leaky capacitor (electrolytic or solid tantalum),
since these do tend to fail with age, vibration and extreme
temperatures in a car environment.

5) If the radio is at fault, you will need some knowledge and
electronic instruments to find the problem yourself.

A quick way to check an electrolytic or tantalum capacitor
is with an ohm-meter. Connect ohm-meter to the capacitor,
and watch the reading race to infinity as the capacitor charges
up. Then reverse the leads and watch it again. Once charged,
the capacitor should have infinite impedance.

6) If the radio is not at fault, it could be dozens of other
problems, ranging from the body control computer,
immobilizer, remote starter, parking lights, door-locks,
alarm system, bad wiring ... you name it.

7) You should be able to isolate it by measuring the battery
current, while pulling fuses one at a time.

8) Another possible cause is the battery itself, or a bad
(shorted) diode in the alternator. The best way to check
the alternator is with an oscilloscope, while the car is
running.

A bad diode will show up as a missing peak in the otherwise
regular pulse train.

9) Finally, don't over look the relays in the power distribution box.
These can over heat and stick in the ON position with the
ignition turned off.

Good luck, Martin

Can't help you with the wiring diagram, but a short term solution might be to put a toggle switch in line with the radio power lead, perhaps at the fuse, and just flip that switch to take the radio out of the circuit. Once you have solved the problem then remove the switch. One way to do this might be to take out the fuse for the radio completely and add a switch and inline fuse with an alligator clip on each end of the switch/fuse wire assembly you have made and clip one clip at each end of where the fuse plugs in. Once a permanant repair has been made, remove the assembly and plug the fuse back in. Be sure you are disabling the right power source to the radio. There are two. One for the memory function and one for the switched power function. If I were a betting man I would bet it is the one for memeory function since that one is not every turned off. Of course when you disconnect that one it will cause you to loose all your station presents and clock time, but at least your car will start and you will know which circuit is killing your car battery. My first guess would be the output module for the radio is about to fail. Just a guess, but maybe this helps. Later man. Good luck

Blaupunkt cancun cr63 car radio


I'm having the exact same symptoms and have had the same luck online. My guess is that the logic got fried during the "brown out" while trying to crank the engine on a very low battery. I thought I might find something about the "VF" and "SK" modes that it is getting into (pretty cool if I weren't missing my radio stations). I'm guessing they are European bands or something. Also getting into a CD changer mode - funny since this was a pretty low-end cassette tape model. My Cancun is 12 years old. What I'm going to try (when it stops raining) is to disconnect the battery leads for 15 minutes or so and then reconnect to see if that clears out the radio memory (if I could easily identify the correct fuse, that would make the process much easier but, alas, I can't). Let me know if you have tried anything else and I'll let you know if my attempt works.
