Re: Blinky Winky Yamaha Test Light ?
You can make one. It's just a 12v lightbulb. I might opt for an LED. A trip to Radio Shack would supply you with all sorts of possibilities. I think one of my old Merc 4-stroke school books shows how. I'll try to find it. Stay tuned...<br /><br />It wasn't in there. Here's what I think would work (haven't tried). Basically, you supply + to one side of the bulb. The computer flashes out the code by providing the - side in sequence. It would be safer for the computer if you used it's 5v reference voltage and an LED rather than a 12v bulb and battery voltage. Look for a Blue wire/white tracer and a red wire/black tracer. I don't know which is the reference voltage and which sends the signal, a voltmeter would probably help with that. Just connect the LED to those two wires. I'd probably hook it up permanently somewhere under the hood. Again, I haven't actually done this. I'm going by wiring diagrams.
Does anyone have one to sell or rent?<br /><br />Thanks
