EHC Lost its memory one morning

Energy One

I thought I would just post what happened to me yesterday morning after working all night.

I believe my EHC lost its mind for the morning. I get off work in the dark and turn the ignition on only to get the two yellow right and left turn Led lights on the tachometer blinking together with all 4 turn signal lights also blinking and the head light is off. It is almost exactly like you pushed both right and left turn signal lights to turn on the emergency flashers except I didn't do that.

The other difference was there were no Dakota Digital lights on the Speedometer. No button pushed would change this condition.

So, I turn the key switch to off and remove the seat and then turn the ignition key back on. The EHC Fault LED lights all light up for what seems like a long period of time (normally they come on and go right out leaving the Yellow Power and Green Controller On LED lit). After all the LED lights go out, then the Yellow PC LINKED and Red Memory Check lights are left on and that is all I get.

After about 12 attempts to get something else to happen, I get a ride home. It has been very wet the previous three mornings but this morning is not bad with 99% humidity and 60 degrees out.

I go back to work with the truck and trailer (the only time I have had to trailer my bike) and the bike is back to normal after sitting in the sun all day.

Why the PC linked LED stayed lit, I don't know. But since the Memory Check lights stayed lit, I am going with my bike had a lapse in memory.

Again, I just thought I would share this.

Thanks for sharing I have an 05 mastiff have not had any trouble whatsoever . I ordered PDM a few weeks ago because I would like to get out of town without something like that leaving me stranded.

my suggestion to you is pull your electrical connections apart and waterproof them yourself. Use di-electric grease on all pin connections and silicone the electric control housings on the bars. By the way do you have a solo seat on your bike or a one up. I noticed that the dogs have a solo seat that terminates before the high point of the curvature of the seat allowing dew to build or rain to flow under the back of the seat and go directly onto the electrical turning into gremlins( alittle movie reference).I changed over to the one up seat just for the extra water shed protecting my electronics from just these kinds of problems. Me knocking on wood. Hope this helps in some small way. 8Ball

I am actually thinking that this may have to do with the Dakota Digital not coming on? You just never know until you know.

I am planning to replace my ground wire from the battery after removing it and thoroughly checking it out because I don't want this to be the problem and a good quality ground wire is important.

There was no moisture running down any cable to the Battery Box. Everything was bone dry under the seat. There was no rain and only normal high humidity. I have never had problems running in the rain. But thanks for the input. I will remember this one.

I didn't do anything except go home and go back to work in the late afternoon. All was good with no problems in the afternoon or after sitting on the trailer all night the next morning. I haven't been able to reproduce this yet.

I will put it on the list to see if unplugging the speedo will reproduce this

I wish I had more money.
When the HID headlights came out for the dogs people had issues similar to yours. Just an idea. May be totally unrelated.

I have had my Adjure since early spring but that is a thought although the Adjure uses the same bulbs as stock vice HID.

I don't think it is the speedo either.

Until it happens again, I won't be able to figure it out.

I thought I would post an update.

I checked the ground wire and found it to be approximately 0.5 ohms. So, I re-crimped the ends and re-installed it.

We will see! I haven't had any problems prior to checking the ground from the battery to the connection on the drive assembly.
