Rear Alternator Condensor

[mshac]

Just know that a condenser and a capacitor are one in the same. They act as a small "reservoir" of current, catching small spikes, and smoothing temporary low voltage situations. If you've ever had an RV, think of it as the rubber bladder that stores a bit of water pressure before the pump has to kick in. Unless there is electrical noise or interference with your radios, I would not be overly concerned about it.
