Replaced batteries in a month or 2 will still not start. Gone through 5 new batteries, and checked fuses, new spark plug too.replaced starter. Is there a possibility any of the wiring causing the batterys to go dead? ANY HELP WOULD BE APPRECIATED.

Why would you replace a new battery just because it was drained? Are you testing these batteries to see if they are drained or shorted? No need to replace drained. When you connect the battery cables does the final connection draw an arc, if so you have a short.
