When is the front cooling fan supposed to run?
w/ no load & just turning it on cold, the fan sometimes runs & sometimes doesn't run. Also, long after a heavy load is finished, the fan will often not shut off by itself. If I turn something small on then off, the fan will then stop.

I have installed it as directed in your note. There is plenty of ventalation. It is not behaving as a thermal fan should as I described above.
Incorrect set up can actually affect fan operation, first ensure correct installation. 2 positive and 2 negative cables must be used. The negative cables must be attached directly to the battery negative post, no chassis ground. For a 3 foot run use 4 gauge cable, do not use jumper cables and clamps, this must be a permanent bolt and nut installation. Adequate ventilation and mounting away from heat sources is required. The fan is a thermal activated fan so it will come on and off as needed to cool the circuit board down. For further assistance, please contact 1-877-619-6321.
