ehc problem????

[330-DAN]

Ok so I posted awhile back about when u turn key on and all that happens is flashers like a cars hazards, also turn indicators on speedo flashed. Many stated battery, so I replaced battery. It was ok for a while but last weekend started all over again. Just flashing, nothing else would work and no crank. Checked all connections, battery, ehc, ign, etc.. finally started. Rode twenty five miles, stop fueled up n no start. Just a click from seemed to be under seat. Started, rode on and all the sudden the flashers start again while riding down road. Happens twice, hit turn signal and canceled it out both times. Its intermittent so never know when it will happen.
So I'm tempted to order a wire plus, just thought I'd get a few more inputs on this before I spend the money on the wire plus. Anyone have any similar issues and find the problem? ?? Any input will help. Thanks!!

Have you checked your charging system?
The symptoms are classic low voltage issue.
The clicking under the seat sound are your compression release valves.
08 Ridgeback so you might have the newer "Smart EHC" which had far fewer problems compared to the previous versions.
Try this:
Press the left blinker button and hold it
Now, while holding the left blinker button, turn the key on
After turning the key on Continue To Hold The left blinker button
This should put the EHC in a self test phase, if its a "Smart EHC".
It will spend a few seconds in this phase and if it finally goes through the normal key on cycle and ready to be started you will know you have no EHC issues.
If it seems to be stuck and not switching to the start phase then you may have an EHC issue.
This only applies to the newer "Smart EHC'"s though and the only way I can know for sure that you have one is by the Revision Info on the side of the EHC

I had the same thing, signal lights flashing no oil light or neutral light.

OK heres what i found....
Battery voltage 13.7( UNHOOKED) and the battery is new (4 mths old.)
I disconnected the battery,starter lead,all battery wires hot and ground and the EHC. cleaned all contacts . The EHC had old dielectric grease( looked real flakey) in it so i used a small fine brush and got all the old gunk out and used Q-Tips for the rest. Loaded some NEW Dielectric in the connectors (all inside the battery area) and reassembled

SUCCESS reassembled everything and WALLAH all lights work and she fires right up.. Only thing i can think of is a bad connection on the EHC. The reason i say this is i cleaned all the battery contacts BEFORE anything else and this didn't fix the problem. So i think the ehc may have had a OPEN circuit somehow???? Only thing i can think of is vibration as a factor for this to happen. I hope this helps someone else down the road. Oh and after this i checked the EHC lights and only have 2 that come on now. CONTROLLER ON / POWER
NOW LET'S RIDE
I Want too thank KaptinAmerika for the help....

I agree with the Kaptin, the next time you get it started put a meter on the battery terminals and verify your charging system is working...

 

[Sven]

I agree with Brew who agreed with... I would unsnap some connectors, see if any are green in color at the prongs? That says contacts are intermittent is a possibility.

So, green in the contacts is the green stays in the wallet. Start looking at every connector you can replug back in.

Nice work Kap

Hey thanks alot.. ill take my fluke home this weekend and test the charging system and also try that proceedure (kaptin) suggested.
i did pull ehc harnesses the other day and notice dialectric grease but like (cavcom278) , it was kinda crumbly looking. ill take some new grease as well to put on them.


hey kaptin are you talking about trying that when it acts up?? im guessing thats when you want me to try this?

 

[KaptinAmerika]

Sure but you can try it at anytime.
If there are fault codes it should notify you.
Thing about the fault codes also is it doesn't necessarily mean there is something wrong with the EHC it just means something happened in that circuit.

 

[330-DAN]

i see.. ok ill give it a shot and see what i come up with. thanks, ill let you know what happens.

 

[Brew]

One more thing is to make sure the circuit breaker didn't trip or if you have the inline fuse, check it and make sure it didn't blow...

 

[330-DAN]

tried the ehc self check but seems not to have the smart ehc, key on just goes straight to normal function just like i wasnt trying the check, unless im doing something wrong but followed it step by step, several times.
havent tested charging system yet, ive got the breather off and enricher out right now but will test once i get back together.
Brew, what circuit breaker?? and if that was the case would it act up then start at times, or just not start?
Im also going to put new dialectric grease in ehc terminal connectors just in case as cavcom278 did on his. ill follow up with any results that i come up with once i get to the piont i can start it up again.

 

[330-DAN]

Ok so far all ok, charging system good.. Starting fine. Added dialectic grease. Time will tell. Guess if it acts up again I'm gonna just get a wire plus...

 

[Nukeranger]

You seem to be headed down the same path I went.

What should it be? "B" ?

 

[07bigdog]

Mine was doing the same. Did the self test and all the lights would stay on the EHC. Lots of times after turning on the key all the lights would staylit up on the EHC. Installed a PDM a couple of weeks ago but haven't had a chance to ride yet. Still winter up here.

 

[jon57]

had this on my 05 ridgeback loose connection on battery

 

[KaptinAmerika]

I Made A Mistake In The Instructions
After Turning The Key On Continue To Hold The Blinker Button In
It Will Take 4-8 secondS To Complete
It Will Either Switch To The Start Ready Phase OR SiT In A Fault State
If Its In A Fault State Note What LEDs Are Lit On The EHC and If Any Blinkers Etc Are Running

Ok so far all ok, charging system good.. Starting fine. Added dialectic grease. Time will tell. Guess if it acts up again I'm gonna just get a wire plus...

 

[330-DAN]

Ok ill try it that way this evening (Kaptin).... Gonna try to ride some this weekend if the weather will allow it, so ill see how things go. Only bad thing is it just happens when it feels like it so I never know, it went a month without acting up before our last ride.
Thanks for all the info and suggestions to all.

Hows your scoot doing 330-DAN?

Hows your scoot doing 330-DAN?

Was wondering the same thing Brew. Weathers been terrible in Rogers Ar though. Think it even snowed there the other day. If Dan's like me.....I would have to wait until it warmed up to try it out.
