Don’t learn from the butterfly

-Think and work in logical order and literally follow the direction of the

current whether talking about hydraulic or electrical currents

-Determine whether the error is electrical or hydraulic, but remember: Without specified pressure and flow it is not easy to find the cause of failure

-Check whether battery voltage is correct

-Check whether there is water on the battery cells

-If a lot of water is missing the terminal voltage of the battery may be ok in unloaded condition, but loaded it will drop many volts

-Are the fuses intact and emergency stop and/or key contacts, if any connected?

-Has a lead been shaken loose?

-Are the leads from the power supply correctly polarized, plus to plus and minus to minus?

If the user of the vehicle is present he should be thoroughly questioned about:

-The kind of failure and influence on the system

-For how long has he noticed that something was going wrong

-Has he been “fiddling” with leads and plugs himself

-Has he got hydraulic and electrical diagrams at his disposal
