I have a customer with a 1994 Superglide! When you turn the key on, the right front turn signal comes on, and stays on bright, also the bike turns over, but does not start, turns over really good! He did not check for spark yet, and I haven't been able to look at it yet! I was wondering if the turn signal is related to the issue, I know most of the time electrical problems are grounds! He had the wires run through the handle bars, was thinking issue could be there!

 

The first thing I'd check is to see if the left turn signal bulb is burnt out.
The second thing is to check for spark.

 

Your statement in red rings loud alarm bells! All around HDF and in every section we get a steady trickle of bikes that mysteriously no longer work - after the owner has swapped to apes and done his own internal wiring. I suggest you start by checking the handlebar wiring continuity first, when it is highly likely IMHO that the defective light and other problems will all come to light! Thrash that to death before being distracted to other things.....
