I had to add a separate 30 amp circuit for my fan & I upgraded to a higher =
capacity alternator. I also discovered that having very good electrical con=
nections is important. I had some high resistance connections initially tha=
t caused some issues but it was caught soon enough to avoid a meltdown.Gary
