Hey all. 96 Sierra here.
So I'm experimenting with pushing a little more voltage to my blower motor, but I've been having some trouble with a seemingly simple task.
Ok, so I've used voltage step up converters on model aircraft and they're pretty straight forward. The converter has a certain input and output vdc range and amperage rating. If you make sure all of that is within range, you can use the pot on the converter to get the desired output voltage for whatever device you have connected to it.
So ive been trying to apply the same logic here.
I bought this converter from Amazon - DC DC Voltage Step Up Converter Boost Power Module 10-60V to 12-97V 1500W 30A CC CV https://a.co/d/7dBAWOX
And I used 10awg wire for all my connections and tested everything on full speed to take the resistors out of the equation.
Here what the issue is, finally lol.
I ran the pos/neg from the car side fan motor to the input side of the converter. Then, turn the car on, fan speed full, Output NOT connected to the motor, tested output vdc and was able to adjust the output vdc across the full range it's spec'd for. I wanted to set the voltage to like 15 or 16 vdc before I connected it to the motor.
But when I connect the output wires to the motor and run it, I cannot adjust it. It just shows about 12vdc output and that's it.
I've tried this on two different converters.
Anyway, it doesn't make sense, or at least I can't make sense of it. Disconnected from the motor, I can adjust output vdc, connected, I cannot.
Do you guys have any idea what I'm doing wrong here?
