+3 for this request
I currently have the 90amp GTR alternator (which was rebuilt by a bunch of incompetent monkeys when it failed 3 years ago)
When I run aircon and I stop at the lights, the voltage goes down to 12v and the hicas starts tripping out whenever it dips below 13v... most times im running 13.5v when the aircon is on, constant 14v when its off with a dip to 13.5 at idle when ac not engaged.
spoke to the auto leccy today, he reckons its a case of not being enough amperage going thru (and i have added a sub, amp, etc) so its probably not a bad idea.
i do have a question for you all tho - is it normal for air conditioners to draw that much load? I thought the alt was supposed to maintain constant 14v even at idle, so im not sure why me revving the engine would cause the volts to rise - which leads me to suspect the alt
any advice is appreciated very much
