Silverado Z71 Driver Information Center Message After Installing Radio
 

Hi, I just installed a Ham Radio in my 2004 Silverado Z71 Truck we used a fuse tap when I start the truck I get this message "battery not charging" it goes away right after I start the truck and I do have the radio off when I turn the radio on It shows about 14.5 volts so the alternator is working the fuse I'm using is for a rear window wiper which is not installed on my truck it has a 15 amp max I do have 2 15 amps fuses installed on the fuse Tap. The black ground wire is attach to a 10mm head bolt that is under the driver side aera by the OBD-II port not Any help would be appreciated

Thanks
