Haltech + brake + battery light= stranded
Need some help ASAP guys. If Anyone sees Hal tomorrow please ask him to call me.
Uprev flash had failed a few times to prevent o2 codes from being thrown. No big deal. Today after oil change had brake and battery warning lights come on and stay on (parking brake was NOT on car drove fine for a couple hours of running around, errands not track.
In gear going down steep hill something gives... No power. I'm thinking limp mode. Engine reves great but won't pull once clutch is engaged. Pull into liquor store parking lot..... Send seven year old daughter in for some whiskey. Car won't start like battery is dead. I'm guessing alternator issue.
Mech found a fuel leak during oil change and tightened AN fitting off drivers side fuel rail. Using my mad deductive reasoning skills looked to see if the helpful fellow may have pushed something loose or some such thing. Found some wires that may have been pushed againstblock that were pretty hot.... I dunno.
Jumped car and lights were suddenly gone and got home. Ran flawlessly. Started up again right after but will try again in the morning.
Single Dad without time to tinker much unless I want to find My little Ponies wedged in various spots of engine compartment and need to drive back down south Sunday 250 miles to home with secure parking. Can't really leave car here and afraid to get stranded for good with kid on some God forsaken back country road around here.
Any ideas?
Thanks Guys

age of a battery doesn't mean it's good. Batteries sometimes get bad cells in them or if the contacts aren't that great it can cause problems.
always easy to start small then look further if it's not the problem.

Car ran fine for half a day. Then Brake and Battery lights came back on but in a different manner. Now they were rev dependant, got noticable brighter as the engine reved higher. Then dissappeared during if I let engine revs drop. interesting

Thanks for input guys

def a charging system issue. On the surface, sounds like the internal regulator in the alternator has gone
easy enough to check with a voltmeter
how does the battery gauge in the center cluster read at idle? at low/high rpm?

ah sorry, didn't see you had a G35 in your signature
easiest way is to put a volt meter on the battery, take note of what it says at idle, have a friend press the accelerator to about 2500 rpm, take note of the voltage then. With the car off, it should be in the 11.5-12 volt range. At idle, around 12.8-13.2 ish (I forget the exact #'s, it's in the service manual though), and then a touch higher as rpm's are introduced
