Symptoms of a bad or destroyed EHC

Last night I think my EHC quit. No symptoms or problems starting at all. When we stopped for fuel, when I went to start up there were no lights except for a dim oil light on the speedo and a low buzz from the EHC. Checked battery at 12.7 volts.

Did you check your circuit breaker to see if it tripped?

First question is - Has ANYTHING been done to the bike recently (Maintenance, washing etc) before this happened?
Check the battery connectors are tight.
Remove EHC and clean contact and use dielectric grease and re-install
Test starter by removing green wire and jumping the post to the 12v stud (make sure you're in neutral)

To start off, the bike had been performing perfectly. No problems cranking or anything weird. The battery has always been strong during cranking. The only thing out of the ordinary was I hit a pothole that jarred the bike pretty good. Today I'm going to check the battery and possibly replace it but I'm pretty sure the EHC is gone

I would check your connections and do as Jersey suggested. The ehc seems to always start out with weird stuff going on for some time before completely taking a crap. The pothole could have knocked something loose. Best of luck.
Thanks will do. Yea i just can't believe it would stop working. No burnt wires or smell of electronics shorting out.

Some do go out “a lil” at a time but mine went all of a sudden, tried to crank it and starter wouldn’t stop, turned key off and it still kept goin until I got green wire off

Connections all looked good. Just had the battery tested a few minutes ago. The guy said there was only 7 volts. Bought a new battery just hope thats the problem. He also identified the negative terminal was showing signs of arcing. Will soon see later today.

Oh yeah nothing looked out of the ordinary when I pull the EHC apart. No smell of anything burnt.

It seems as though your battery could have shorted or just plain gave out. Regardless , After you put the new battery in be sure to check that the charging system is working. Should be 14-14.5 vdc while running.
If your battery did short out it very well could have taken out your EHC at the same time. Once you get your bike running be sure to protect your EHC from a shorting battery by putting a fuse or circuit breaker between the battery and EHC. The CB installed on your bike only protects the battery from a VR short or over-voltage but does nothing to protect the EHC.
