So, heres the skinny. Just installed my EDP turbo on my 2014 GT A6. The kit came with a slim dual fan setup from Jegs.
The fan came to me, already wired to the output of the resistor. Both fans are paralleled.
While data logging, I noticed that the temps were getting higher than I liked. After some observation, the fans were only coming on after 210 ECT or the A/C was on. I verified with my tuner that the low speed is triggers at 185 in the tune. ( Swapped the HS & LS relay, to verify both were operable )
What this boils down to it that the low speed resistor has failed, MAYBE because of the load of two fans instead of the one OEM unit.
My question: There is a 40A max fuse for the cooling fans. There is a high speed relay and a low speed relay. At the resistor, there is a ground, and two 12V+ feeds, one is HS, the other is LS.
If I remove the resistor from the picture, parallel the grounds for the fans, hook the 12V+ from one fan to the LS and the other fan to the HS..... when the HS fan is on, will the LS wire still be energized?
The ultimate goal is to have the PCM control the fans. One fan on for LS and the second comes on for HS.
I guess the last option would be some crazy ass bundle of relays and diodes. In that case, I welcome any of you to offer a schematic of how that would work.
