With older vehicles there are often problems with the electronics. To fight as a layman through the tangle of cables is often more tedious and often parts get exchanged, what does not need to be replaced, or suddenly other electronics errors appear elsewhere. To avoid this, we offer the possibility to test the electronics and, where appropriate, overtake at the points required. You can specify both a complete harness to be replaced, and sometimes just a simple fuse, that has to be known first. Especially classic cars are tricky.
