Notes: BWW tower sensor. One of the mount screws wouldn't come out initially; Joe got it out pulsing with vice grips + WD-40. He cleaned out the white dust inside the bolt holes with a thread cutter. He sprayed the bolts and bolt holes with a anti-corrosion spray before I installed it again. The 7550 temperature sensor was bad. I replaced with a repaired homemade temperature sensor. The HMP fan was not spinning, but it seemed to work fine after I removed a bit of fluff.
