Code 3 RX2700 Wiring Question

[markhart]

I recently purchased several Code 3 RX2700 lightbars from a municipality that were taken off vehicles that were being removed from service. The harnesses are different on two of the lightbars, and I would like to power them up to test them before selling them. I hooked up 12 volts to the heavy red wire and negative to the heavy black wire. From looking at the wiring instructions, I should get various lighting when I connect the smaller gauge wires to the positive connection one at a time, but when I do I get nothing at all. I am using a fully charged jumper battery as a power source and I have tested the output with other lights. Can anyone tell me what I need to connect to power it up? Thanks!

Try your vehicle battery sometimes jumper packs don't have enough juice.... Also check for internal fuses

First step is to always pop the top, and check fuses, if there are any. My experience with the 2700 says there are none, but that doesnt mean anything.

I have also found that my jump box isnt powerful enough to power Liberty I/O boards, so it may be the same with the 2700

I’ll give it a shot from my truck battery and let you know what happens!
