This is an update to my thread. Being a mechanical engineer for more than 50 years it was frustrating for me to find the problem with the blown 20amp fuse. Mechanical problems you can see electrical problems you can't .I went to our local Scag dealer and was told that to find my problem could take hours. At $125.00 per hour I was determined to find it myself. Now, for all you DIYers I like to share with you a UTUBE website. Go to realfixesrealfast.com look for "finding a active short" and watch the video.This is not only for cars and trucks it is for all electrical wirings . The tool he used (Circuit breaker and amp. probe) I found the the store who sells it.
Handsontools.com. Click on Shop all dept,s, than click on Diagostics, than click on Circuit Testers, scroll down and you will find the tester KD 2524D short circuit tester for $30.00 I bought the tester and it took me less that 10 minutes to find my problem. It was so easy and simple. I know there are other ways to test electrical circuits, with multimeters, amp probes ect. but you still have to test the effected wire after you find it. To OHM out a wire is not accurate if the wire is broken and still hangs on 2-3 strands you will get a continuity reading and you still have to make a voltage drop test. Hopefully this will help someone
