1989 jeep Grand Cherokee 4.O L
first owner 18 years dealer serviced, less than one year previous owner decided to install a security system and high powered stereo...
He disconnected the security system before I bought it in 2007
drove it for about 8 months was perfect...
Then radiator bottle cracked and killed the alt..
Had a new one installed it was fluctuating wildly.. mechanic said it checked out as well as the battery ~then it stabilized ~then on a hot day ~ ac on ~radio on ~brakes in ~ stuck at a train crossing ~ alt died.
Jeep sat for over a year...
Just had it serviced, new alt, new battery ~ seems good, but the turned on the AC and saw it fluctuating~ dropping slightly. drove a couple miles then it was up to 14 again.
Concerned since this is similar to what happened with the previous alternator.
Was told the last alt had a very bad short by the mechanic who just changed it out. first time there...3rd alt~ i am thinking it is something else.
I need the car to be reliable enough for 200 plus mile trips through the desert. plus daily driving in LA.
Engine is great ~no over heating ~ everything, else so far checks out, brakes a bit soft ~ but it's been sitting for over a year...new spark plugs oil change/filter...lube.
Advice please.
