Along with a other gauges I installed a new VDO electronic Speedo p/n 437-151. Well it won't work. First thing, the install instructions say that when the indicator is first powered up it does a self test and the gauge needle will sweep across the whole range. That doesn't happen. When the gauge is powered up it reads 0.0 in the odometer space and the needle bounces a bit. When driving the needle is parked at zero. I installed a hall effect transmitter in the transferase p/n YBE100530. not sure about it. I odrede if off Amazon and it came from china. Quality is suspect.
I did call VDO technical support, they won't answer the phone or reply to my message so they are no help.
I have triple checked the wiring. its getting power, and the ground is great.
Any suggestions?
