On the bench today is a HP 5385A frequency counter which seems to have a short to ground on the 5+ rail. Fixed: The 5v over voltage crowbar protection circuit was being switched in, because the 5V rail became noisy/ripple (+/- 700mv ripple voltage).

Replaced the aged smoothing capacitor on the 5v switch mode power supply output. That fixed the ripple and stopped the over voltage issue the zener diode was tripping on.
