Trouble Analysis

The trouble in the electric system is divided into line trouble, which caused by wire crack or circuit short, and

parts trouble, which caused by parts wear or fire. On the other hand, according to the service and maintenance, the
system that approaches the final life car easily has trouble.

When check the circuit, first check the harness for wearing earth or cracking if exist please wrap up or con-

nect and continue to check.

If the circuit has no problems, check the parts associated with the system to find out causes.

If the fuse burns out frequently during the operation, please check the harness for wearing earth and the out-

put voltage of generator to see if over loaded.
