Slow crank

Ok guys to see if its a cable issue in going to disconnect existing battery cable and run short factory style short ones and put battery on fender to see if its a cable issue or further in. Battery cable for positive was getting hot after attempting to start last night. Will report back after test!
Thank you all for the help!!!!
PLEASE don't do that ****. It will not "find" the trouble. Use your meter and make some measurements as /similar to what I outlined. FIND the problem. By doing this kind of thing you change the problem so much that you are only guessing in the dark. This may be as simple as one bad terminal on one cable
