Turn Signal Relay Conversion Question- 85 CH150D

Post by kjkenney »

So I have a four prong female connector on the harness of my CH150D. The relay went out about a year after I purchased the bike so I do what I always do and found a decent looking used one on eBay. Get it, it doesn't work. Thought it may have been the control switch on the handle so I cleaned it 3 separate times to no avail. So instead of rolling the dice on used ones, is there a way to convert mine to use a "universal" relay that I can buy new? The style that this bike uses seems to be exclusive to this bike, from what I can see, and I miss my Aero 50 being a lot easier to fix with these types of things.

The manual shows it as two wire, which it is not. It has two greens and and one blue with yellow stripe and a mint green with black stripe. So it looks as if each side of the signals, Left and Right, have their own circuit in the relay. Maybe I just don't fully understand how these work (I don't), but I'm having a hard time understanding how to convert it. Anyone taken this step or ever had a necessity? I know it should be a very simple part of the circuitry, but the 4 prongs confuse me :?:

Need pictures of this 4 prong unit. Biggest issue with turn signals is dead bulbs... you checked those first? Also, they need to be incandescent bulbs, as the flashers won't work right if the electrical load is off.

I'm looking at the CH150 wire diagram now... it looks just like every other Honda scoot I've seen. 2 wire. One of the wires will have power 100% of time. The other is a draw wire; when you switch blinkers on it completes the circuit through that wire and the turn signal relay starts flashing. Note that this is a fused connection, and apparently that scoot has 3 fuses... so check those first.

You'll need to start troubleshooting. Of those 4 wires, at least 1 if not 2 should have power, and the harness would go back towards battery. The other two probably go to signal lights.

Here's a 4 prong flasher output. Note 1 pin is 90 degrees to other. Pins are ground, +12V, +12 dash panel, and to lights. This is a generic module... should be able to find at an auto parts store.
