The engineers tried out my new tester on a fuel injection computer

few
load dump cycles. I think that's why they went to side terminal
batteries.
? What's the difference in transient voltage handling between top
and
side term batts? I thought the difference was merely physical
config.
Bummer on the quick trashing of your tester.
The fuel injection computer was destroyed, not my tester. The solder
holding a thick solid wire to the top of the stud-mount clamp Zener
melted and the wire popped off. The next high-voltage discharge
wrecked the module before I could run around the engineers and stop
it.
Do side terminals corrode?
