:rant:STILL cant get my 2004 RidgeBack to start.......I had the starter rebuilt by Wild Steed Worx,installed a MONSTER Braille battery,cleaned and lubed all battery connections,grounds are all good..... When I turn ignition on,NO LIGHTS AT ALL come on with the EHC,when i hit the "RUN" button a red light comes on solid and stays on,when I turn it off, red light go's off.........

ALSO the red LED on the Thunderheart Ignition module does NOTHING,its not lighting up at all.........WTF IS GOING ON HERE!!!!!!!!!!!! I'am ready to drop a quarterstick of C4 in the tank and remote Detonate this MOFO...:bang:

Thanks for any help I get!

I actually was having the same problem, (Sorda) Do you keep your battery on a tender? Is your stator plug plugged in all the way? Try to wiggle the EHC plug its self, Last but not least get the old multi meter out and start tracing where power is going

how do you lube battery connections ? -- but i would check to see if your battery if fully charged then check the main fuse/circuit breaker (maybe you shouted something -- then disconnect starter if that is the last thing you had done and check to see f you have lights -- starter may be shorted? -- i doubt it is but you have to eliminate some pieces....

Send your ignition modual to Thunderheart. Theyll check it for free.

Cool Info thanks man I will send the Igntion module out to get checked ASAP....And you lube battery terminals with a thin coating of Dielectric grease, it works great!!!!!

Busted out the Fluke DVOM and took some readings.......Ahhhhhhhhhhhh The green wire to the Solenoid is ONLY getting 5.25 volts.....have checked all the grounds and complete harness in the battery box....its all good......Took the starter BACK outta the bike,hooked it up to battery charger and bench tested it............works great........

Sooooooooooo I assume the EHC has shit all over me,because that is the only thing that controls voltage supplied to the solenoid.........anyone else got any clues???? Iam totally stumped on this......EHC is all I can conclude

Are you positive you connected all your wire connections to the battery terminals? Sometimes when changing out the battery a wire will slide down and get over looked. Are your plugs getting wet with fuel? Just a few things to check.

Didnt even bother checking the plugs for fuel because the starter doesnt even turn the engine over, it just barely kicks the drive out,then it gets stuck on the ring gear and I gotta push it back in.....and yes I triple checked to make sure I didnt drop a wire anywhere....This is so weird.........the bike was great when I test drove it,got it home and it completely shitout on me.....

I did everything on that checklist,and took the starter backout and bench tested it,it works great outta the bike, put it back in,and it barely kicks out starter drive....Tested the EHC solenoid wire...it only gets 5.25 volts.....So i guess the EHC took a major dump on me??????? Time for a PDM rewire maybe.I dunno

If your getting voltage to the solenoid then the EHC has done its job at that point. Turn the ignition on put a voltmeter positive on the starter motor terminal and negative on the battery. Hit the run button and then hit the start button and watch your voltage. You should be getting at least 12 volts, but more like 13.6. If your getting 12 volts but the starter isn't turning over, you have a primary cable issue, or your getting less than 12 volts, then you have a battery issue.

Just curious... you're getting 5.25V on the green wire to the solenoid with it disconnected from the starter, RUN button pushed, and START button pushed? What are you getting to the compression releases?

Also, make sure your starter and EHC have good grounds...

My bike has manual compression releases on top of the heads, and trust me I have triple checked the grounds over and over......

DD Tell me if this sounds familiar, Bike will turn over but no start, no light on the thunderheart and a red light on the EHC for Ign. This is what I did. Took the red wire and cut it before it goes into the EHC and stuck it on the positive battery post. Pushed the start button and the red light came on, on the TH module, Bike starts and run. Now to shut it down I have to take the wire off the post. Thinking of wiring with a switch. All I'm doing is bypassing the EHC IGN. Everything else works. Remember if you do this the only way to kill it is to disconnect this wire.

I know you might not want to cut the wire but after going through all my troubleshooting with my fellow Helicopter electrical buddies, This is the only thing I could do to get it going. Of course I don't want to accept the EHC is bad but the IGN is the only problem. I even changed the key assembly with no change. Original was a little loose.
Was running great for 25000 no problems and then it would just shut off but everything else was normal.
Let me know what you find out

Even though you have manual compression releases there's still the output wire coming from the EHC, true? That's what was asking about along with how you were measuring the 5.25V...

How did you check the grounds? Just asking...

The strange voltage to the starter is a dead giveaway. Assuming everything is grounded properly, as you say you checked, it's a bad EHC. Sounds like your Ign module is getting power, have you checked the coils? Despite what's going on with the EHC if the ign system is functioning and getting power then the bike should start when you manually engage the started as shown in the "starter won't turn thread". The only thing that would keep it from starting would be an issue with the coils or ignition.
