Issue: rear brake does not trigger brake light
1: brake light bulb is good
2: front brake switch triggers brake light (proving bulb is good)
3: all fuses test good
4: BMU pins 54A, E2, and E1 have been jumpered together and pins 58E and 58A have been jumpered together to effectively take the BMU out of the equation.
5: with rear brake switch connector disconnected, shorting the two pins at the connector does not trigger the brake light (thus taking the rear brake switch out of the equation)
6: there is continuity between the rear brake connector and E2 of the BMU
7: there is 12v at the rear brake switch connector
8: the BMU instrument warning light turns off after riding ~5 minutes and does not come back on while riding.
Thanks in advance.
