Hi there,
I have a 2004 Polaris Scrambler HO. Initially the overheat light came on instantly when starting and the fan never came on while operating it. After research it seemed I needed a new ECM. I replaced the ECM which fixed the initial problem however now, after I turn the unit off for more than 5 seconds, when I go to turn it back on and start it nothing happens. There's no power at all, no lights, nothing. If I unplug the new ECM and plug it back in then boom, everything comes back on. This is every time I turn the key off. Any suggestions would be greatly appreciated!

Thanks,
