My Ranger is blowing the 5 amp primary fuse every once in
a while when
I turn it on. I have checked for any kind of intermittent
short but
unable to find anything. I am now suspecting inrush
current. My Ranger
has all the power supply mods. Solid state HV and LV power
supplies
with 330mfd LV cap and 165mfd HV cap. At first did not
suspect inrush
current due to having choke input filters but I suppose
with the solid
state rectifiers and the large caps it maybe happening.
Does anyone
have any suggestions to limit this inrush current in the
Ranger. Also,
does anyone know what the Ranger's nominal current
consumption is from
the 117 VAC source under full load? Any info is
appreciated. 73, Randy


You might try a slow blow fuse. You could be right
about the inrush current with the solid state recifiers and
much larger than original caps.
