Hi, i am new to this site so be friendly as i am not as intelligent as others lol. I have bought a dvd/cd unit and wired it upto my car, but it is keep losing its memory on the unit. I have tried reversing the 12v live and 12v switched wires around and it still loses memory, I have also conected the constant live to the battery with an in line fuse and it is still losing memory. I have tested a little further with my mulit-meter on the direct line from the battery and the cars 12v live and switched wires and here is my results. On all 3 wires i have permanent 12 volts or over when the car is not cranked over. When i crank the car over they all drop to around 10v approx for a second or two until the car starts and they go back to 12v when running, I beleive i am losing the memory feed when i crank it over. Is there anything on the market what will hold the voltage whilst i crank the car over? here are the unit specs: Supply voltage 10-15v, current consumption 4~15a (this i am not to sure on! any pointers on this is much appreciated).
Just off topic i have an electronic boost gauge which calibrates itself when i turn the car on to the 1 position, when i crank the car over it loses power and goes through the calibration test again, is this due to the same fault as my car dvd unit as the power for the boost gauge? Thanks in advance for any replies Ian
