This is a strange one to me... I've got my new portable fridge in the boot, currently running of the cig lighter socket in the rear (soon switching to aux battery).
Strangely when the compressor is running the volume of the AM band on the radio is reduced and there is quite a bit of static. Only on the AM band though, not on FM or on CD.
I'm familiar with alternator whine effecting systems but never heard of it interfering with one band only?
Any suggestions on cause/solution?
