What might be wrong with 2007 Grizzly 700

Was out riding recently and everything was fine. All of a sudden, it started to misfire and lose power. I looked at my POD and the check engine light and EPS light were on steady-not flashing. Luckily, I was close to home and drove it back home and as soon as I got into the yard, it died and wouldn't start. I pushed it into the garage. I turned the key on and Er1 popped up and also codes 12 and 42 and another number or 2 on and off. I went back the next morning and it started right up but various numbers kept popping up on the POD, namely 12 and 42 amount others. I called my dealer and he said it's maybe my CDI box or a bad ECU. What do you think it might be?

farmboy, First off; Welcome to the site! I'm just sorry that your first posting has to be about a problem. Now I'm on a 660 and know as much about EFI as Hogs do about the Sabbath... but I'd check electrical connections first. Make sure that stuff is actually grounded that is supposed to be grounded... Do you have any of your connections in the wiring that have soaked up some water??? Di-electric grease in each one should eliminate that problem. Once you've got that sorted out, I'd be guessing that the dealer is leading you in the right direction... Good luck and let us know what you find!

WELCOMEto the gang Farmboy ...

I'd do like Bob suggested first as well as, make sure your battery cables are clean & tight. My brother Can-Am acted up like that & it was a loose negative ground wire on his battery.

And let us know what it turns to be ....

Er-1 = ECU Internal malfunction (output signal error)
- No signals are recieved from the ECU

12 = Crankshaft position sensor
- No normal signals are received from the crankshaft position sensor

42 = Speed Sensor
- No normal signals are received from the speed sensor

FWIW, Grizzled700

Gee... You're sounding like a guy who's stood over his Grizzly with a long face watching those very codes appear...

Bob,

Actually had that long face looking through here and my Yamaha Technical Service Manual as my 07 700 died and will not start... get no codes at all and all the DIAG options look fine. Now starting to meter out all the **** sensors...coil is ok...crank position ok...TPS ok...lean angle ok...rollover ok...cleaned air filter, was not dirty but did notice oil and found drail line full of oil. I will figure it out, just may take a while ;0)

Update: Finally got the Griz back from the dealer. He had to replace the regulator and the stator and said that should fix it. I hope so.
