Testing front wiper motor ?

[dvddvddvd]

I accidentally left the front wipers on when van was warming up, and the windscreen was covered in 3 inch of snow.

Now the front wipers do not work anymore and fuse 17 keeps blowing.

I have taken wiper motor off and there's a 4 pins connection 1 2 (3) 4 5,
There are 4 wires coming in, to test which pins do i connect up to bench power supply ? had meter on it and seems pins 1 3 and 4 are to earth ?
The fuse did not blow again with motor disconnected.

thanks

This any use? Pin 1 is the main earth. 2 & 4 will be the slow & fast speed while 5 will be the park switch. As you are testing a powerful motor the windings will show very low resistance. Personally it sounds like the motor will have burnt out. illyme:
See if it smells like the wifes cooking !:lol: alut:
