Jinma 354 wiring diagram

I can not help you with a diagram but just cause a wire is hanging does not mean that it is being used, everything works on my two Chinese tractors and there are wires coming out of the harness hooked to nothing. where are these wires located?

I can’t help you, because I have the same problem. When we split the tractor last week to repair a leaking bearing seal, we disconnected the wires on the alternator without making a record or using taps to show which wire goes where. When we put it all back together, the tachometer won’t work and we think we hooked it up wrong. The diagram in the manual is useless. Did you ever find something or someone that refers to the colors of the respective wires and where they go?

ps: my tractor also came with extra wires just hanging down, but everything worked fine.

I have 2 Chinese tractors I can look and see if how they are wired and give you that info , but that does not mean it will work for you.

Some tractors have the tach wired off the alternator, others use a magnetic pick up on the flywheel housing.
