Hi John,
Can you tell me more details about the power jumopers located on the "top of the terminal block" I dont have much electrical knowledge and thought I might replace this board on my own..since mine blew on a 2003 Sovereign last week. I dont want to do more harm than good if I dont know how to properly set the right jumopers please advise Marc

: You need part # 73355 (Kit, Heater Board Replacement). It is a simple
: fix, but there are a couple of potential problem areas that you must
: watch out for. First, exercise typical electrostatic precautions
: around the main board and the new heater relay board. Second, and
: very important, watch the power jumpers located in the top of the
: terminal block. The replacement board comes with a two-pole and a
: three-pole jumper in place. The problem is that the configuration as
: shipped is rarely the correct configuration. Failure to set these
: jumpers properly can cause massive damage and cost a small fortune to
: repair. Be careful.
