So I notice that the little light that indicates gear position will not turn off pretty sure its draining battery but idk but when I bought the truck it had a hid unit installed but they didn't work so I removed then but I'm still losing battery juice so if someone has any idea what could be goin on please let me know

 

You'll need a voltmeter. Hook it to the battery, then individually pull fuse's till the voltage drop stops, that will get you to the circuit(s) that's causing the issue.

 

wont really work too well with a computer

 

I’m fighting the same problem. Also pulled the radio battery fuse and the voltage drop seemed to stop. Not sure if the instrument cluster needs work or if maybe the ignition switch isn’t turning the light off. Perplexed. Any help would be appreciated

 

you'll need an electrical schematic to trace the fault

 

I can look up a wiring diagram for you I just need these details to select the right options in service information:

-Year
-Engine size
-4 or 2 wheel drive
-Model and trim package

 

Replaced the neutral safety switch and PRNDL light is now off. New problem is it idles really high in park and neutral

 

Mine is a 1998 Silverado 4x4.(K1500,SWB,SC, 350CID) I have a "radio" fuse and a "radio batt" fuse. What is the "radio batt" fuse? Bringing the battery back to full charge tonight. Hope to start serious testing tomorrow.
Thanks!

 

The radio batt fuse is a direct battery feed to the radio for memory and communication after key off. The radio fuse is an ignition feed.

Neither fuse powers anything but the radio unless the wiring has been tapped into for aftermarket accessories.

 

Thanks for the information.
I've pulled both radio fuses and the drain seems to have stopped.
Now, if this thing didn't have a DIN AND A HALF radio!
Don't want to use a single DIN and fill the gaps and I'm not crazy about modifying the entire dash to squeeze in a double-Din.
