Just to clarify, you got the 75 from Errin? But he doesn't sell Boondockers, Randy does. What does the label say on it--PM4-75 or PM4B-75? Also it looks from Randy's site that his labels say Boondocker but the PM ones say PowerMax. What does yours say?
Here is a photo of my prototype adjustable 100amper. It is a much modified PM3-100. Randy's new adjustable ones are similar except no carrying handle it seems.
Here is that strain relief I rigged for the jumper cables I use for it as a portable
I used a bit of red tape to mark the pos terminal better. I have since used a marker pen to add gradations around the knob for some settings such as 13.6, 14.8 so I can set the converter voltage even when it is attached to the battery which skews the voltage showing on the meter some.
