Re: supercharger clutch noise
Let me tell you a story.
i liked the idea Steve had so I added an LED to the I/C pump and the S/C pump. Nice.
Went thru the tech inspection on Saturday, when the hood closed it pinched the cable that I used and it shorted out the 12 volts blowing the I/C pump fuse. I was in line and had to do my runs without the pump, and it got hot, intake was at about 210 degrees measured inside the plenum.
I have since rewired the circuit so that the led has a 1000 ohm resistor at the source end of the cable so that a short further down the cable just blanks out the led. THe fuse and the pump or S/C will operate as normal, just the light is off till its fixed.
FYI, Woody
LEDs operate at low voltage and need to have a current limiting resistor, positioning it on the INPUT end of the cable makes it a more bullet proof design.
