I don't think that hooking it up to 12v only will advance the meter. It probably needs a Tach signal to advance. I called the manufacturer of mine and asked for the signal spec. Then hooked it up to a signal generator for the appropriate number of hrs.

As for why it is reading "no data" ... perhaps the plug is not wired the same as the old one. Is it an OEM replacement? S
