Im having the exact problem with my Murray mower.
I have got power to the left lug of the new solenoid the cable from this goes back to the battery live. but Im getting nothing going over to the rightside of the solenoid, no clicking when turning the key, but when I bridge the lugs on the solenoid the motor turns over no problem, is this new solenoid broken or have I placed the wires back in correctly
