my friend owns a 02 civic DX and she is having problems with the alternator, the problem is that mechanics are telling her that she has too many electrical devices running in her car, only one amp rated at 1500w, and some angel eyes, and that it is draining too much from the battery and alternator, is this bullcrap or is it true? if it is true can she swap another alternator from a different car to make more power? thank you very mucho!
