[QUOTE="mfenske, post: 2456963, member: 566364"] Anyone know anything about this: From Autosound 2000- ISOLATING RELAY N-52R $18.90 Order N-52R .:| Here |:. The N-52R is a 12 volt relay that is completely isolated from the vehicle. The input resistance is over 1000 ohms so the on current is less than 15 mA. The Normally Open contacts of the secondary relay are rated for 20 amps. Connect +12 volts DC to the trigger input, and 12 volts, at 20 amps will be at the output. Is there any other relay that won't cost me $20 that will do the same thing because the power supply for my XM Radio is noisy as hell. Disconnect the DC adapter and the noise goes away. [/QUOTE]
