I cringe at reviving this thread - but.... I am hoping DaveO is watching....
I wanted to verify that the e-fan conversion I did (some time ago) was behaving correctly, in terms of when it turns on and off.
DaveO knows my configuration - he provided all the info for the install (thanks Dave!). I have dual flex-a-lite 220's wired in to a VSC (variable speed controller), and the the stock accessory e-fan wiring - to take advantage of the automatic cutoff etc.
So to check when the fans are running (or not), I spliced in wiring for a small LED light to the main power and ground line (the power and gnd that goes from the VSC to the fans), then I ran the light inside, so I have an indicator light when the fans power-up.
I tested while idling - works fine - the fans go on, the light comes on. The fans turn off, the light dies.
But, I noticed something interesting while cruising... when I get to around 65-70mph, the light gradually comes on and gets brighter as I increase speed over 75mph.
My suspicion is that the fans are off, but the spinning blades are generating a current above a certain speed causing the light to come on. Would you concurr - or are the fans turning on at higher speed?
My goal is to ensure the fans are not turning at speed - this does seem to be the case. The clearly are turning off everytime I go above 25/30 mph. But curious about the behavior described above - thoughts?
