Hi there,

Thank you for the donation,

I would start with a current draw test on the electrical system, this is where an Amp meter is placed between the battery pos terminal and the battery cable and with all doors shut and key out, check the current draw, get your mechanic to do this test, if he can't let me know and I will give you a full description of how to do this simple test.
