Car taperecorder

[Haya Khan]

Dear Members

Hi,
I am really happy and pay thanks to the forum and honourable members Mr. Johnholl & Mr. Diblue in that I have daignosed the car battery leakage at my own through their valuable guide lines.
The problem is not rectified yet but is isolated to the Remote Controlled door lock system (solenides).
At present it is disabled (fuse removed) and the car with the same battery & alternator is woking well.
As the car tape & door lock solenides are sharing the same electrical circuit, it has damaged the tape before as mentioned earlier in the "battery leakage" that once, while starting the car with 60/70 amps battrery, the 100 amps alternator fuse blew off. The tape also was damaged.
I checked the tape and found one IC # XLA3915B is not working. I searched the local market but could not get the IC. I found that # BA3915B is the exact replacement to it, but un-luckily it is also not available in the local market.
Therefore, once again I request the honourable member to help me out to procure this IC.
Thanks & Best Regards
