fluttering aimlessly from flower to flower in a

BE THE BLOODHOUND
-Sherm
4
-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
5
-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
6
-Are the fuses intact and emergency stop and/or
key contacts, if any connected? -Has a lead been
shaken loose?
7
?
-Are the leads from the power supply correctly
polarized, plus to plus and minus to minus?
8
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
9
-Has he been fiddling with leads and plugs
himself -Has he got hydraulic and electrical
diagrams at his disposal
