["Chapin, Tim" <tchapin bf umich edu>]

I think I confused people...  this is a Lester golf cart charger that I
am getting together for an old golf cart.  Being a non electrical guy I
just assumed that a golf cart charger of the same vintage as the et
charger would use the same caps.....  I am getting the idea that they
can be very different.  I will try to get some numbers off the Lester
charger cap tonight.  The thing is very rusty and don't think I can find
any.

Or you can just buy them from Harold Zimmerman and be guaranteed of 
getting exactly the right part.

Happy Harold customer
