Troubleshooting 

Troubleshooting the engine protection system requires additional information from the manual that is supplied 
with the Muirhead

®

 EPS system. As a guide, a typical engine protection schematic is provided in this manual. 

During  troubleshooting,  inspect  all  components  and  connectors  before  any  components  are  replaced.    If 
connectors  are  not  tight  and  clean  they  can  cause  intermittent  or  permanent  electrical  faults.    Ensure  the 
connectors are tight and clean before any other tests are carried out. 

Failure of an electrical component can cause, or be caused by the failure of one or more other components.  
Always  attempt  to  find  and  correct  the  cause  of  the  engine  protection  system  failure  before  replacing  a 
component. 

Tools needed: 

■ 

Part no. 2005 

– Digital Multimeter x 1 

■ 

Part no. 7599 

– Circuit Tester x 1 

Digital Multimeter 

Use  the  part  number  2005  digital  multimeter  or  equivalent  for  making  continuity  checks  and  voltage 
measurements. It is recommended that the circuit tester, part number 7599 or equivalent only, be used to test 
the three outputs of the EPS control unit. 

Note 

If  the  EPS  system  is  being  installed  in  conjunction  with  an  idle  timer  and/or  a  fire  status  control  unit,  it  is 
imperative  that  the  units  are  installed  in  the  correct  order.  Failure  to  do  so  may  result  in  the  machine  not 
shutting down correctly. 

Refer to the appendix at the end of this manual for the correct sequence.
