Roy,
I have a later manual for the 732A. P/N 788414 May 1986. This manual
shows the little 3 pin connector labeled J10 for the battery module. The parts
list shows a Fluke stock #720844, Mfg 89536 (Fluke) and Mfg P/N 720844. I have
long since removed it from my 732As and replaced it with two minature banana
jacks (2.64mm) red and black. There seems to be some sort of Mfg mark on the 3
pin connector but I cannot identify it ( I saved the old 3pin connectors). If
the manual you downloaded is from the Fluke website and is named
"732A____imeng0000.pdf" or "732A_Users_Manual.pdf" you will see a
"Change/Errata Information, 7/85" list in the front of the file. Change #5
changes the battery connections to the spade lugs and Change #6 changes the
banana jacks to the 3 pin connector.
You were very wise in removing some metal from the top plate to allow plenty of
room for the spade lugs on the new batteries. I didn't do this intially and
one of the battery terminals shorted to the metal plate and fried the + 18 volt
regulator assembly, which took a few days to fix. My opinion of the 732A vs.
the 732B is that since the 732A has been around longer the references have had
a longer time to stabilize. The only issue I know of 732A vs. 732B is the
battery life. The 732A battery life is around 12 to 15 hours without being
powered. The 732B specs the battery life at around 72 hours. This makes it
easier to get it to Fluke in Everett WA without losing the "IN CAL" light. My
experience is that even when started from cold after being off for a long
period of time they will stabilze at exactly the voltage they had when the
power was turned off. It does take a few days however.
Bill
