Hey guys,
Found this in my service manual for the 2003 model ehc.
For all 2003 models the rear LED assembly serves as taillight, brake light and turn signal. There
are three wires that connect the rear assembly (red, green and black). The red wire powers up the
taillight and the green wire powers up the brake or turn signal and the black is the ground for the
entire assembly. If the brake lights do not work then try a turn signal. If the turn signal works,
then the wire to that part of the assembly is good. There is an open connector position on the
EHC that can be used to determine if the brake problem is in the EHC or the wiring or brake
switches. Position number 5 on J4/P4 connection at the EHC (see schematic) can be used to test
for brake lights. Using a small skinny metal object (for example, a paper clip) that will go
through the connector housing, push through the connector so that it touches the contact on the
EHC side and then clip a jumper wire on the metal pin and then touch the other end of the
jumper wire to the positive terminal of the battery. When this is done the brake lights will come
on. If they do not, make sure that the metal object being use is indeed touching the contact in the
EHC and if so then the EHC should be replaced. If the brakes light do come on then the problem
is in a brake switch or the wiring.
If a brake switch is defective such that the EHC is getting a brake switch signal when the brake
levers are not being operated then the turn signals can be used to determine this condition.
Normally if the brakes are on all the time one can tell by the brightness of the LED’s but if not
then turn on either of the turn signals and count the times that it blinks before shutting off. If the
signal goes past the normal count and does not shut off then one of the brakes switches is being
activated and should be checked. For this test to work the bike must NOT be in neutral. Refer to
the electrical schematic when performing these troubleshooting tips.
