Bike won’t crank

[Triker9999]

It’s a 1988 1500, it’s a reverse trike conversion, last yr everything worked fine, started, shifted, etc.. I get it out this yr to work on n it won’t crank.. good charged battery, the starter button is working, I hear a clicking on the left side relay, I jumped the b starter relay n starter turns slowly not fast… what safety switches are there to get starter button to work? Kickstand switch? Neutral switch? Any more switches I can test? Also on the b relay wiring plug which slot is from starter button so I can test that? Hopefully this makes sense how I’m explaining it.. lol
