moxie1990

I drive a 1996 hilux and off and on for the past 6 months the oil light and battery light have been coming on. Sometimes it comes on for half an hour occasionally, sometimes its on constantly and then sometimes it never comes on. I was told it may have been the alternator, but my battery always has good charge. I am still able to run my 1000w amp for hours without my battery dieing. I dont know what else it could be. Can anyone help?
