I've got a 98 camaro SS with some electric problem's... it's got a new alternator,primary wiring (i,e battery to fuse box's,alternator,starter.. )
and starter on it haven't checked the battery yet...

I was on my way home yesterday and thing lost all power and died!
now it will start when boosted and shows good with the boost cables on.. pull them off and it drop's to about 5.5volt's at the battery after it warm's up... when you first start it, it shows 13.9volts at the battery....

the #3 fan relay is getting hot in the fuse box under the hood as well even when the car is turned off...
what fan is that? I can't find anything about a 3rd fan any where in the manuel's on the car...

 

check out on everything before leaving your house.so it will not be a messy trip.check on your battery always.
