I'm not sure if this is the correct area to post this but if its not sry. I was curious about an Electrical drainage problem I've ben getting since having the car. I have a brand new stock alternator and brand new battery, however everytime I put on the rear defrost and stay idle for a while my interior lights begin to dim out.. when I shut it off.. everything lights up a bit until I press the gas... Sometimes it begins to dim out when the norm defrost is on @ idle for a while but I notice its when I turn on the rear defrost more.. Is this a common problem for the MKIV turbo Supras?? The only mods I have done to the car is the HKS EVC EZ 2 BC, Greddy BCC, Rmm DP/GT-Spec, HKS SSQV bov, Autometer Boost Gauge, Greddy Turbo Timer.. Any help will be appreciated.. ty.
