hello all. my name is norman and i am a proud owner of a 2008 mastiff w/efi that i have owned for 2 years now. ride locally which is why it only has 3350 miles on it. and here is my problem: rode it to lunch the other day and washed it. rode it back to work just fine. went to leave 3 hours later and it acted like the battery went bad. on first key, speedo cycled like it should. primed when run button was pushed. hit start button and it just clicked and speedo had the flashing lights and odometer flashed in and out. just as if the battery had dumped. took it out and put it on the tender all night. put it back in and it all acted the same as the night before. load tested the thing and volts were good, but cca were only at 92. bought a new one charged overnight. installed it and turned the key on. speedo self check was normal. push run button and can hear it prime. push start button and nothing. no clicks no nothing. here are the checks i have done: pull side cover and check leds on ehc. amber pwr led is solid, green controller is flashing. ign led does nothing when run is pushed. have 9 volts at green wire at starter with key on. but does not change when run or start is pushed. pull b connector off ehc and check ohms at b6 and b28. circuit is open at first and closes 1.2 ohms when start is pushed. check rh pcb and ohm results are the same on both run and start button. open at first then closes when buttons are pushed. even went as far as jumping the run and start pins at connector for the pcb. primes when black and red are jumped but nothing when black and green are jumped. re-did batt connections as a double check. still nothing. not sure how to check circuit that pwrs the ignition led on ehc. is there any other checks i can do to confirm ehc is bad before i ship it off to have checked?
