Friend of mine just picked up a '90 244 which overall is in great shape. One major problem I came across so far is that the fuse for the right-hand parking lamps and the instrument lights blows as soon as the parking lights are turned on. The weird thing is the first time I put a new fuse in, the lights worked, but then a few moments later it blew and installing a new fuse blows as soon as the switch is on.
I plan to do some old fashioned troubleshooting this weekend to track down the problem but I'm curious if anyone else has come across this?
