I have an 83 kz550 m1 shaft drive. Went to go start it one day and no power to the cluster, no power when i switch the key to on. Good battery, Good fuses, Good connectors as far as I can tell after checking with a light meter. It's been rainy here. Attached video tells more.
You need make up a simple circuit tester if you dont have a multimeter and check each connection starting at the battery. I had a similar issue with a repro ignition switch. Power was ok all the way to the switch but nothing coming out when on. Took the switch out and the main power in lead had disconnected from the solder point on the back. Cheapo repro parts from China!!!!!
Hey all, figured out it was the fuses in the wrong slots. After checking those and putting new ones in it fired right up. Also if I took a wire brush and brushed the fuse clamps the lights and gauges turned on. I brushed them free of any corrosion and found out this neat trick that led me to my solution! Also used a diode wand to check battery and power flow through all my connectors and wires.
