You proved the start circuit is good up to the TSM. Did you check battery fuse?

TSM: Turn Signal Module. Turn signal switches give an input to TSM and then it provides an output to the lights. 5-8 do you have 12 V on 5 & 6 when you push the corresponding switch? 12V on7 & 8 when switch is pushed?

When you turn the ignition and kill switch on do you have 12 V on 1 - BN/GY and 2 - GY at the TSM? Is wire 12 BK common to ground?

We replaced the fuses with new fuses, Not sure if the BK wire is common to ground, I see in the diagram it is the ground wire for the TSM. I just tested the BK #12 wire to ground and it is common.

Not worried about the turn signal just yet but I metered the terminal 1 BN/GY and Terminal 2 GY. without the ignition on or the Kill switch I have 12 v. Once I turn on the ignition and Kill switch I have .54 Volts

Look at the partial schematic below. The Battery fuse should have 12V all the time, as long as the Maxi fuse and Battery are good. It doesn't even go through any switch.
Connect the Black lead from your volt meter to the battery negative or a good ground. Red meter lead to battery fuse, you should have 12 V. Ignition off measure to ignition fuse, 0 V turn Ignition on, 12 V.
Check at the TSM connector again after verifying 12 V at fuse block.

What did you read doing turn signal checks?

Had to leave town for work but will try it tomorrow evening when I get home. Didn't have time to check directional's, but will when I get home.
thank you so much for working with me on this. Learning a bunch.

I have 12V for the turn signals when i press the respective right and left button

I have checked the ignition fuse and it is fine and the battery as well has 12.79 V
Left turn signal showed 2.4 V before I pressed the button and 12.59 after.Not sure why I would have a current draw on the left
Right turn signal shows .01 V then 12.39 with button pressed.

One more thing I was told, When they jump started the bike they connected it to a pickup and it was running. So not sure it something burnt.

You need to verify the TSM has 12V on the BN/GY with ignition on or off. Connect the black lead to battery neg and red to the connector 30B BN/GY wire, 12V?
Do the same with the GY wire, you should see 12V to ground with ignition on 0V Ign off.
If you do find both wires have 12V with ignition on plug connector 30 back together and see if you have 12V on the RT and Left turn feed with the blinker switch on.

Doing these tests tells us if the TSM is getting power via Battery and a signal that ignition is on with GY wire. You verified 12 BLK is a good ground so with power to 1 and 2 you would think an input on 7 or 8 would get an out put on 5 or 6.

Look at the page from Ronnie's and check which model TSM you have, 11 or 12. Good link if you don't have it. http://partsfinder.onlinemicrofiche.....asp?make=hdmc

That's not a good way to do it, the truck's charging system may damage your bike's own electrical system or the battery. Only jump with the motor off if using a car or truck.
