EHC power ro Thuderheart ?

[hayseed]

hello,,, i am trying to firure out why the hot lead coming form the EHC (red/green/black) to the thunderheart module always has 8.6 volts coming out with the key on or off,,,then with key on i press the run button on the handle bar contol in jumps to 13 volts, and hit the stop button goes back to 8.6v ?

anyone ever experience this or next time they are in doing dsome poking around can they place a volt meter probe inside the connector touching the red pin over to the negative batterry terminal and let me know the results --

Did you ever figure out what's up with the constant voltage?? I am getting the same 8 volt constant only with key on at the signal wire to the starter and trying to figure out if its normal

i have not figured out why or if its normal,,, so yours has 0 volts when the key is off, key on is 8 volts and the run button pressed its 12.xx volts ?

Same for me. Key off 8-9 volts. Key on, run = 12 volts.
