Wiring Aging on Mercedes Classic Cars
« on: July 01, 2024, 11:14:58 »
Dear Friends

Much have been written on the matter, but many have not realized the danger on which their loved classic  Mercedes are on catching fire.

I am working in a harness for a customer with a rare W112-300SE COUPE 1964.

The harness showed normal aging signs, but once all PVC tubing was removed, the extensive damage was revealed in detail.

  • T30 lines (always hot-non fused) have completely compromised and absent insulation, that happened on segments exposed to heat, and also inside the cabin
  • T50 starter selenoid activation line, shows external insulation softening

So my friends, please make your harness be serviced by someone with patience and attention to details.

Those two major lines have in my opinion always problems. So replace them.

Here a link for a photo album, with high resolution pictures.

Best regards
