My motorcycle oil pressure gauge is low and the voltage gauge is maxed. Whats the problem?

Oil Pressue low....when? at idle, at operating speed? HD's run about 10 psi at idle, and most guages read 40-60 at operating speed. If it reads lower than those #'s, you most likely need a new oil pump. Take it to a shop and have them do an oil pressure test.How many miles are on the bike? If it has more than 30,000 on it, you want to have the cam chain tensioners inspected for wear. If they are worn to the point of needing replacement, that could also be related to the oil pressure situation. The worn away material tends to damage the oil pump, causing low pressure. If you need to have the pump replaced, DEFINITELY go with the new Screamin Eagle Pump/Cam Plate Upgrade. As far as the charging goes, you need to have the charging system checked out, if it's over charging, most likely the voltage regulator is bad.My motorcycle oil pressure gauge is low and the voltage gauge is maxed.

I don't know which, but if the oil pressure gauge is electrial and not mechanical, the two could be related since the oil gauge actually measures the amount of current flowing through it and not the oil pressure itself. The sending unit is what measures oil pressure and uses that to impede the flow of current through the gauge.





I guess the first thing you need to do is to check the voltage at the battery when the engine is running to see if it really is overcharging. If not, then it's time to start checking electrical connections and go from there.
Check for a faulty ground wire to the gage cluster.
The wires go switched.
