I am fixing an electrical fault on a BMW R1150R (2001). I have traced the fault to two wires that have abraded and shorted together where they enter the connector beneath the fuel tank. With a bit of tight fiddling I can repair the two damaged wires. The problem is trying to get a clean area to work. The whole area around a cluster of about six connectors is covered in some kind of black gunge. My guess is a previous owner has sprayed the area with something to keep out moisture and over time it has accumulated grime.
Can anyone recommend a good product and method for cleaning up this area, prior to beginning the fix?
Any advice is most welcome.
Kind wishes - Patrick
