 +===== BASIC TESTING of Turn Signal Wiring =====
  
 +==== For 1991 - 2013 Models ====
 +Disconnect the Turn Signal Module from the wiring harness connector. Testing will be done on that wiring harness connector.\\
 +For 1991-2003, the module is under the seat. For 2004-2013, the battery must be removed to withdraw the module located under the battery.
 +
 +Look at the [[techtalk:​evo:​elec03#​turn_signal_modules|wiring diagram]] for your module. Identify the FEED OUT & SWITCH IN pin numbers as shown on the diagram.
 +
 +Identify the two wires (BROWN wire for RIGHT-side & VIOLET wire for LEFT-side) that feed power to the lights. Find the two wires (WHITE/​BROWN wire for RIGHT-side & WHITE/​VIOLET wire for LEFT-side) that are incoming from the handlebar switches.
 +
 +The connector pin with incoming power is Pin2, Accessory Power, using an ORANGE wire or ORANGE/​White or GREY wire. __**BE VERY CAREFUL HERE!**__ This power is fused but will allow many amps of power to flow before blowing. BE VERY CAREFUL not to short this pin to ground! ​
 +
 +**BEING VERY CAREFUL** not to short any other pins:\\
 +With the TS module disconnected and the Keyswitch **ON**, CAREFULLY put a jumper __BRIEFLY__ between Pin2 (Power into the module) and the pin that is identified as RIGHT FEED OUT (BROWN wire). The RIGHT TS lights (both front & rear) & indicator should light up.
 +
 +Now, CAREFULLY move that jumper __BRIEFLY__ between Pin2 (Power into the module) and the pin that is identified as LEFT FEED OUT (VIOLET wire). The LEFT TS lights (both front & rear) & indicator should light up.
 +
 +\\
 +
 +Now you need a multimeter to check the incoming signal from the handlebar switches. Set the meter to 20v DC voltage. Place the BLACK probe on a good ground. The connector will have a BLACK wire for ground on Pin1 (for rigid mount models) or Pin12 (for rubbermount modules). See the wiring diagram.
 +
 +With the TS module disconnected and the Keyswitch **ON**, CAREFULLY put the RED meter probe on the pin identified as RIGHT SWITCH IN (WHITE/​Brown wire). Press the RIGHT-side TS Switch, then check the meter to see if it is getting the 12v input signal.
 +
 +Move the RED meter probe to the pin identified as LEFT SWITCH IN (WHITE/​Violet wire). Press the LEFT-side TS Switch, then check the meter to see if it is getting the 12v input signal.
 +
 +\\
 +
 +
 +==== For 2014 - 2021 Models ====
 +ONLY THE OUTPUT wiring to the Turn Signal lights will be tested. Because the handlebar switches use the CANbus to communicate with the BCM, it cannot be simply tested.
 +
 +Disconnect the Body Control Module (BCM) from the wiring harness connector. Testing will be done on that wiring harness connector.
 +
 +Look at the [[techtalk:​evo:​elec03#​turn_signal_modules|BCM wiring diagram]].\\
 +All the BCMs use the following pins for power to the TS lights:\\
 +Front Right - PinJ2 - BLUE/Orange wire\\
 +Front Left --- PinJ4 - BLUE/Pink wire\\
 +Rear Right -- PinK2 - BLUE/Brown wire\\
 +Rear Left --- PinK4 - BLUE/Violet wire\\
 +
 +Pin1 has constant BATTERY POWER - __**BE VERY CAREFUL HERE!**__ This power is fused thru the Main Fuse which will allow **40amps** of power to flow before blowing. **BE VERY CAREFUL** not to short this pin to ground!
 +
 +With the TS module disconnected and the __KEYSWITCH OFF__, CAREFULLY put a jumper __BRIEFLY__ between Pin1 (Power into the module) and one of the above identified pins. As power is applied to each pin, the identified TS light should be lit.
