[ARC5] Capacitor Tests

[AKLDGUY]

It's been rare for me to experience a failure after long-term running in a
high ambient temperature situation. Most of my failures have been in the
coldest months. It seems that it's the rate of temperature rise from a low
base temperature that puts the device under the most stress.
