In open ignition switch, and open the wiper switch when the first or the second gear (can be a low speed or high speed), measure the wiper motor is different from the outside of a 24 v voltage? Control (the anode) if you have, can prove that line and the switch is normal. Point of failure in the wiper motor.

There is also a situation. The excavator is to control the negative (term) which requires the positive pens and pick up on the 24 v power supply, multimeter and negative pens and after open the wiper switch, ordinal measurement plug if there is a loop, namely 24 v electricity. If you have, can judge fault parts in wiper motor, if not, you should check the fuse and switch.

According to experience, failure rate is higher, in turn, are: fuse, wiper motor.
