ive just wired up my prosport guages and wanted to try one so connected it up with just the ignition on, the power and sender unit plugged in when they finished their start up process the light was just flashing on and off. Anyone had this problem? I tried another guage to make sure it wasnt just that one and that was the same.

 

no signal from the senders.if its oil pressure it will flash till its running.I would just check all the connections as they arent the greatest,just check all the little connectors on the back are firmly pushed in.
