Diagnostics according to plan:

General:

● Before changing any expensive components, Bomag BW 120 AD-4 / BW 125 AD-4 Service Repair Manual such as control units, you should run a systematic troubleshooting session to eliminate any other possible fault sources. Knowledge in basic electrics is required for this purpose. If a fault was diagnosed without having pulled the plug of the control unit or inspected the wiring, this should be done before changing any parts.

● Check for good cable and ground contacts, therefore keep all mechanical transition points between electric conductors (terminals, plugs) free of oxide and dirt, as far as this is possible.

Well, structured troubleshooting procedures can save time and money.
Random tests have revealed that purely electronic components or control units only very rarely are the actual cause of failures:

● In approx. 10 % of the examined cases the problems were caused by control units.
● In approx. 15 % sensors and actuators were the
cause of the problems.

By far the highest proportion of all faults could be
traced back to wiring and connections (plugs, etc.).
