hello everyone
before anyone asks, i have searched this subject and have noticed many a problem relating to the alternator. now onwards!

it's been 4 years since i've owned a rolla and managed to get my hands on a 91 GTS, y question (s) is/are these: the car wont turn on. new battery installed last year and still no joy. i can start it with a boost, once started it will run but that's it. there are no dash lights, all gauges work, dome light and such works and the marker/parking lights are always on regardless.
If i go to use anything with power it almost kills the bettery good. Also the previous owner had installed an aftermarket Cruise control and i believe he failed horribly. anybody know what might cause this. if it helps, i doesnt matter what i do cause after i turn the car off after any length of time it will not turn back on unless i boost it.
cheers and thanks in advance.
