[DeTomaso] NPC: Losing caps on my battery

[asajay at asajay.com]

Stock vented caps.  But with that said, I can't be sure they actually  
-were- venting.  Those that blew off are now free to roam wild in the  
highway.

I'll be measuring voltage later tonight to see if I can figure what's  
up.  I also have an induction ammeter that I'll try (oh wait, my Dad  
has those, drat!)
