I have been trying to track down a speedometer problem, come to find out at 2000 RPM's it is charging a little over 18 volts which I think is to high, also noticed win I unplugged voltage reg. quite a bit of oil came out of connection, can oil migrate down the stator wires to plug? A test light between ground and reg. pins shows nothing but a digital meter shows .14 volts at each pin, is the reg bad? terry
That was actually common on XLs in the early 2000's. When they charge that high, the speedo usually stops working. They also pop bulbs. You need a voltage regulator. Verify the stator (electrical tests) and battery while repairing.
If it's an FL, depending on the year there was a lot of oil from the plugs, and they were relocated to the flat plate between the two front frame tubes - thought was oil won't run uphill.
I believe there is a sticky on charging system testing.
