Looks like there taking care of you.. Sorry I was tied up on a job. I'll read through all the post in the morning and see where we're at

I was super busy at my shop today so I told one of my guys to run over to my hobby shop pull every connector they could find, hit it with contacts cleaner, air, and dielectric. Then, put the ehc in and let me know. It fucking worked. It's not the methodical process I wanted to do to find the source of the problem but I'll take it. I still had my run jumper in it and it came to life. Under 6k miles! I have to run over when I can put the switch back in to see if it works. Thank you guys so much for getting me this far!!!

Great News !! Check your headlight and Check for bike in Neutral. Your picture shows the blue light on ( high beam) default is low beam unless the bulb is bad and no neutral light. Probably just not in neutral.
Your second picture is indicating a fault on the circuit related to the position of the light. I can't tell from the picture which circuit it is. Good news you get to troubleshoot it and get a true feel for the process not the shotgun!!
Lube your cylinders before cranking just to be cautious.

Super. Just FYI, your EHC has been upgraded to the 05 EHC with a circuit board adapter. Which it a good thing. Once you get the Deka battery, I going to recommend replacing the voltage regulator. On those old EHC, there is no protection between the battery and the EHC. If something happens to that old voltage reg. it will smoke the EHC.

Great to hear -- This may not have been as methodical but really it was. If it was contacts/dielectric needs and that bike sat, its really better that they were ALL done -- Otherwise you might have done it till it worked and had one fail shortly after possibly while on the road.
Glad we could help get you going.

Yea, since it was picked up at an auction or salvage I'm sure it sat outside in the rain at some point and however long easy for it to get corrosion.

Got some time to check it out this evening. Right hand pcb is indeed bad. Ordered a new updated one. It is in neutral but the brights stay on and when I switch it to low beams it just flashes 3 or 4 times. Had the plugs out already oiling the cylinders. Nice fat spark on both plugs. Battery is coming Thursday as well as the carb kit. Should be ready to fire by Thursday evening. Also, thankfully they got the title and its notorized and ready to pick up. That's the main reason I got it so cheap (paid $1425) the auction house was "pretty sure" the title would be forthcoming but it was potentially not. Ordered new front and rear masters as they're both bad. Hopefully it doesn't have catastrophic engine damage. Can't thank all you guys enough. I don't know if I ever could've figured it out but I would've surely bought a replacement ehc before I did. Looking forward to paying it forward.

that's what this site is all about.
I've said it before, without this site I probably would have given up on BDM years ago (or striped everything out and rewired old school as much as possible give I have an EFI bike).
I have people on this site that I am closer to than any of my blood relatives!

Rebuilt the carb and flushed the tank out and this sucker runs real well. Have to rebuild front and rear master cylinders so no ride yet. Also the neutral light never comes on. Once again, I can't thank you fellas enough for helping me get it running!!

If you take the tach ring off you will probably find a broken wire just needs a little solder and your neutral light will work again. And while you have it apart check the tach connection it’s probably ready to come apart.

You check the plug on top of the trans?

On the way!

Now your down to easy stuff. Neutral indicator switch on top of the the transmission check that first. You can jump the pins on the plug on it just to see if neutral light comes on. Then you'll know if the neutral switch is bad or a different problem.

Just a ground switch, and you wouldn't really think they can go bad, but occasionally they do. Mine stopped working, just replaced and all was well.

This bike is making me feel pretty dumb. What the hellkind of snap ring pliers do I need get to the one in the front master?!?

Need a set for an INTERNAL snap ring.

Internal Circlip Pliers

Internal circlips are designed to be fitted inside a hollow, cylindrical housing or bore. The spring action pushes outward against the sides, so it’s a radiating pressure that holds the ring in place.

Internal circlip pliers work the opposite way around to external versions. When the tips of internal circlip pliers are inserted into the holes on the snap ring, squeezing the handle results in the plier tips closing together. Once the C-clip is in position, the handles can be released, and the ring returns to its maximum diameter.

You can get a cheap set at Harbor Freight if you need too.
