GPR? Please Help

Can the GPR draw power when the truck is off? My batteries seem to drain somehow when my truck is off. Anywhere else that could possibly draw electric from? I have my fog lights and CB hooked to the battery. Why can't everything be mechanical.

No I don't think so as the gpr needs 2 trigger wires to operate. One is from the pcm and the other is from the ignition or when the key is cycled.

It just seems my batteries are lower than what they should be. When i turn the key it makes a buzzing noise right on the dash and i only get a couple good cranks out of the engine. If my truck doesn't start after 2 or 3 tries then i don't have enough juice in the batteries to crank it. I have changed my batteries and alternator many times and have had these things tested multiple times saying they are good, yet my starting power seems low still. I am just out of ideas

I would start by unhooking the fog lights and cb from the batteries and see if they still draw down.

if unhooking the lights and cb doesnt work i would try disconecting the batteries all together for awhile and see if one or both still looses power. If you do that i would get a voltmeter and check them both before your hook them back up, both should be very close to the same voltage.
good luck
