[RFI] Single or Dual-Connector Posts on Battery?

[Jim Hill]

Hi Doc: I'm using a dual-connector pair Interstate battery in my 
travel trailer.  I carry golf cart batteries in my truck (no room in 
the trailer), and use modified jumper cables to connect them to the 
trailer (negative terminal of trailer battery not connected when golf 
cart batteries used).  I've had poor connection problems with 
continual disconnects and connects, causing heating, voltage drop, 
and when listening a hum modulation of CW signals.  I need to clean 
the battery terminals and wire lugs periodically and tighten the nuts 
securely.  Hand tightening of wing nuts is not adequate.  If I seldom 
changed connections, I think I would get regular battery cables and 
modify them to go from the battery to trailer wiring.
