Anyone familiar with the 'oddset bomben' setup? Need help with the wiring.

Hey, have you checked the ground connection? Sometimes a loose ground is the culprit, especially with complex modules like that.

The 'oddset bomben' module is notoriously finicky. It usually requires a dedicated filtering capacitor right at the input terminals, not just straight 12V DC. Check your schematics for that.

Short and sweet: Try boosting the voltage slightly. 12V might be too low for initial startup.

I had the exact same issue. It wasn't the voltage, it was the current draw on startup. You need a power supply with high transient current capability, not just a stable 12V rating. My rig uses a dedicated 15A unit.

Wait, are you sure the module is rated for continuous operation at 12V? Some of those things are designed for pulsed power, and drawing too much current too fast will trip or simply fail to initialize.

Long post: When I first integrated this, I thought it was a power issue, but it turned out to be a timing issue. The module needs a soft start sequence. You can't just hit it with full power. You need a relay or a dedicated power sequencer circuit to ramp up the voltage slowly over a few seconds. Otherwise, the internal components get hit with too much inrush current and fail to stabilize. This is a common pitfall that isn't obvious from the basic wiring diagrams. I highly recommend looking into a controlled power supply unit (PSU) rather than just connecting directly to a mains adapter.

Check your wiring gauge. If the wires are too thin, they will drop voltage under load, making it seem like the module isn't getting enough power.

I used a different brand of power supply. The quality of the PSU really matters here. Mine was cheap and kept flickering. Stick to industrial grade units.

Is it possible the module itself is faulty? Sometimes these custom modules just fail right out of the box. Maybe try testing it with a known good, low-power load first, just to confirm basic functionality.

Have you accounted for the module's operating temperature? If the ambient temperature is high, the power draw increases, and your 12V source might struggle.

Try adding a main fuse right at the input. It might not solve the flicker, but it will at least tell you if the power source is drawing excessive current.

I think the issue might be related to the data lines, not the power. Sometimes the module needs a specific handshake signal to initialize properly, and just applying 12V isn't enough. Check the manual for any required control signals.

Make sure your power source is isolated from any other high-draw components on the same circuit. Noise interference can mess with sensitive electronics.

It sounds like you're dealing with an inrush current problem. You really need a current limiting circuit, not just a voltage check. Good luck!
