Bike Shuts off when turn signal used.

[Guest]

Initially, my turn signals stopped flashing but the bike ran fine. When the switch was engaged nothing would happen or they would turn on and stay illuminated (not flashing). I checked voltage to the relay switch which was adequate, so I ordered an OEM relay switch to replace it. After replacing it, the bike now shuts off(sometimes, not all the time), when I turn the signal switch.

Not sure about the 850L's wiring (you know that dreaded canceling unit and whatnot).

There's so much that could be wrong...what have you done so far, other than replacing the switch? How did you come to the conclusion that the switch is the culprit?

Check you haven't pinched a wire, Is it left, or right or both indication that causes the problem?

Often that is the first clue to low system voltage due to charging system problem and battery voltage going low. Next clue is slow starting next time.
Next clue is engine dieing at some point, maybe when added another elctrical load - - hey, that is what you said happend.

Charge battery with a 1 (or 3/4, or 1.50 amp, not 6 or 12amp) charger.

THen take off charger for half hour or so.
Measure battery voltage with key off, then key on (headlight on), engine at idle, and engine at mid RPM (like 4500-5000).
