So I recently bought a Doran 16 lamp light monitor off ebay... I was hoping to tinker around with it hooked up to a battery and make the lights come on and whatnot... and eventually hook it up to monitor the lights in my car. However, they are a LOT more complicated than I anticipated. I have the wire diagrams but they require the in depth understanding of an electrician... Anybody have any kind of advice to offer? or any similar experiences?

Not entirely sure how to explain it over the net. These things are complex in design, but fairly straight forward in installation.

What seems to be giving you trouble?

Think of it this way, the wire going to each lamp you wish to monitor must pass through the monitor. Example... Output from backup light switch to monitor, then two outputs from monitor to lamps (one each).

The monitor must first have a positive and a negative going to the corresponding terminals or it won't work at all. For the warning lights- there is one input (ie, left amber, right amber, left red, right red) and two outputs (left amber front, left amber rear, right amber front, etc). The circuit must pass through the monitor- as in it must come in one input and go back out on its corresponding output terminal. You could wire in some sort of test bulb in the circuit but if the test bulb doesn't light, neither will the monitor, because that's what its meant to do-monitor lights.

If its a newer unit that monitors incandescent or LED bulbs, it gets a bit more complicated because it will be highly voltage sensitive and the monitor may need to be reset at proper voltage to work.

If you are trying to just wire one in for fun, I suggest get rid of the monitor board, but keep the faceplate and do what txstreetman and I did by building your own board, and in essence building a circuit tester rather than an actual light monitor.

We can't all be conventional!
