Hi Mike an' EVerybody;

Talk to Pete Senkowesky out in Clear lake CA He fixes Raptures, or
might have a few ideas? But ya would have to park the EV while it is on it's
CA trip, the controller, I mean.707-994-1972 or 707-350-0156. Is this Fan
thing contagious? I have the same issues with MY Rapture 450 amp job. With
the Phoenix like weathrer I brought home from Phoenix, but FAR more
oppressive with our humidity, I ran the Jetta about 40 miles and had the
heat cut back feature go into effect. But I weeded out two bum badd-eries,
so amps were high and voltage low, that didn't help!Two reversed cells.
Gees! Wish I could dig out the bum cell and change it with ANOTHER good cell
from another bum battery. Like you USED to in the good old tar seal daze.
Next day the fan ran when ya first key in, as it ALWAYS used to. A self
check thing? All Rapturs did/do that when they are happy.IF you get water
inside or even NEAR them ya get NOTHIN! Wish the controller biz could make
stuff like the Chinese Hai Bao car , of forgotten years past; You could hose
the whole engine/controller dept. out with a garden hose!

But don't get toooo picky, we are lucky to HAVE them, EVen though they
aren't built with places that have weather! Shitty ,damp, cold, drippy,
foggy WEATHER. Maybe as EV history drags on, we will see encapsalated
elecctronics so ya can hose EVerything down, a clean car is a happy car!As I
look out over 70 degreez, sunny weather, lawnmower calling me. Love the
smell of new mown hay!

To get back to the Rapture; I GUESS there is a heat sensor on that board
ya pixed? HOW does the fan know to start?Is it on the heat sink?Where does
24 volts come from, to begin with?I THOUGHT the fan was 12 volts? Ran off
the Key feed?What used to amaze me with ALL the Raptures, I have had, is
that I could drive to work on the freeway , like LA, stop an' go traffic, in
90 degree weather and it be stone cold in arrival at work. Motor hot as
hell, but controller cool. After dealing with early SCR crap,oh say 35 years
ago, sevcon controllers that needed monster heat sinks, fans, the Rapters
were Raptures, they were COOL in more ways than one WITHOUT any radiaters,
pumps and hoses. I guess ya can use a Zilla for a NORMAL car the same way?Do
ya HAVE to have a cooling systen like on the Zombie?

Seeya

Bob
