2002 Overland - new forum user - Admin: if this forum is the wrong place to post this question feel free to move it. Thanks!
A couple of months ago the AM radio in the vehicle started to make ‘popping’ noise and fading in and out as if I was driving in the middle of the desert at night. I thought there may have been something wrong with the radio until I was playing a CD and in a blank space in the audio I heard the popping sound - very much like a plug coil going off.
This Jeep has had its own share of electrical issues; seat heaters, mirror settings jump around, etc. Over the last few years I’ve had to replace the PCM three times - and the second to last time I did that I was told the problem was using the Interstate battery. The PCM remanufacturing place said that was it for sure - and so I took out my 1 year old Interstate and picked up a standard Costco battery - that did fix that problem!
However, now it seems that my driving lights are dim (although they do not brighten when revving the engine) and the radio has this fading / popping noise problem. During the daylight hours if I reeve the engine to 3,ooo rpm the fading of the radio goes away. Add driving lights and the fading comes back.
I’m thinking the problem may be the alternator - and I want to get that checked out. However, I thought I saw that the Overland came with a higher rated alternator.
Can anyone shed some light on the weird radio issue and confirm the correct alternator for this rig?
Thanks ahead of time!
