Actually 2 things on my mind. Speedo works when it wants but only at highway speeds and again randomly. Now blinkers are starting too work intermittently. Any ideas? Don’t believe both switches would go at same time, Short maybe or relay. Not sure and I would appreciate any ideas.
Might be a failing Harley speed sensor. Remove the sensor and see if it needs to be cleaned. Sometimes, fine metal shavings or or a paste like film from normal transmission wear can cover the end of the sensor. This will cause the sensor to work intermittently or not at all. You will find that your turn signal problem is linked to your speedo issue. Your speed sensor reports to your module, information, that is used for signal cancellation based on distance/speed. Check your speedo head for stored diagnostic trouble codes. If your problem is not a bad speed sensor, it may be a bad TSSM (turn signal security module ). If you can pull any codes from your speedo head, it will aid in helping you make a quicker, more accurate diagnosis.
