I have a 1994 Heritage Softail (FLSTC) with an Evo engine, and I experienced an issue where the starter began to engage while riding... that experience sucked, as it happened when 175 miles from home on vacation. I checked with a few forums and HD people, and everyone said it is a problem with faulty relay or handlebar switch that got corroded. I ordered a replacement switch set and relay - I just replaced the old switches (which were corroded and nasty) and connected the battery... even with the center switch "off" and the handlebar switch "Off", the starter still engages. I cannot locate the Starter Relay. It is not under the seat or in the headlight housing or anywhere else I can locate. I am trying to do as much work as I can on her, but this has me stumped. Any ideas? Thanks!
