Battery voltage ⚡️ drop

[LittleMike]

I still have to isolate the ehc with some velcro or double sided tape. I'm not sure if any metal to metal contact is happening there. I did mount all the connectors to the battery to the sides of the terminals and added cushion spacers under the seat. I saw there was some wear marks from the battery to the underneath of the seat.
Interestingly, my metal detector hits hard with a signal on my garage floor but barely registers on the rest of the driveway. I get a reading that points more towards silver than iron. I ran the detector over my test spot in the yard which is a quarter buried 6 to 8 inches and the detector is working fine, it should, it was a very expensive Garrett!

I once had a voltage regulator that had a wire that came through the epoxy or what ever they seal them with it shorted so the battery drained when parked. It only charged between 900 and 1200 rpm going by the tach. Try unplugging the voltage regulator and then check to see if a charged battery drains when parked in your garage.

The coil on our bikes is mounted using fiberglass washers to help with electrical issues. Maybe consider isolating your EHC using them . Cost next to nothing and can't hurt.
By the way, If you haven't already done so, install a CB or Fuse between your Battery + and EHC. Your parasitic voltage drop may decide to get real bad and start taking out stuff like Mick said. It sounds like JohnBoy dodged a bullet with his short.
Fiberglass washers are used when mounting a motorcycle coil to prevent rattle and heat transfer, ensuring a secure fit and reducing the risk of damage to the coil and surrounding components. They also help isolate electrical connections, which can improve performance and longevity. Got that from Ai

I had a drain one time and it turned out to be led decorative lighting strings that got old and fractured. It was weird how I found the problem. I was in my garage one night and turned off the overhead lights and in the dark I noticed tiny sparking along one of the led strips even though the system was off.

My govee lights behind my TV do that, stay on with a very low dim.
I'm wondering if I were to ditch the EHC and use one of those kits that bypasses all this stuff, I think I've read a little here on RIP kits that this issue would be fixed.
Gosh I wish I wouldn't have dumped over a thousand bucks between the EHC, ignition module, cam sensor and speedometer sensor I would probably go ahead and do one of these kits right off the bat.
meanwhile my 2 buds with honda furys stopped by and tell me to dump the chopper for a fury. Those do ride nice and comfortable.

These Dogs aint for everybody thats for sure. Fwiw, I have a rip kit in the Chopper and an Electronix Box from Curtis in the Pitbull. Both take a bit of wiring. Nothing mind numbing but they both have a bit to wire. Choice is as always your's. Curtis n Axel stand behind their product I can attest to that. BTW, the Furbie boys just jealous.

The EHC I got from Curtis was just plug and play, he contacted me and and we got the wiring down so all he had to do was install the correct connector for me and it was a 15-minute install.
He was certainly a decent guy to work with, it really seemed like he wasn't going to be happy until I was happy. Even checked in with me about 2 months later to see if everything was okay and running all right, you don't find that very often from a vendor. I've got some really good suggestions here and I've written them down and going through them and cross them all off one by one. A guy at my local Harley shop told me that it's possible the actual ignition switch that I'm installing might have been the culprit, I won't know until I get that all installed and let it sit on the concrete.

Curtis has always been a stand up guy,

For whatever reason I can’t pull up the photo of you on your BigDog but looks like’04 by the primary case?

 

[Sven]

If the EHC has one big plug to pull off the black box, disconnect and then note the battery draw or not. You might narrow it down to the pack i.e. of wires. On the garage floor bare, no wood, etc.

Yes sir, an 04

Have you tried removing the screws n checking for a voltage drain? Just a thought. Perhaps an internal gounding issue in the EHC? I have a RIP in the Chop n Electronix Box in the Pitbull. Both are mounted with double stick tape... think alien tape. Maybe an option?

I went ahead and mounted the EHC block with double-sided sticky instead of the bolts. Looked over the voltage regulator wires, checked connections on the battery, unplug any connections i came acrossed and reseated them with a little diametric Grease or whatever that stuff is called. I also installed a new headlight bulb and while I was in there looked over the wires and they look good no Burns no twists no half-ass connections.
My Chopper is running real good nice and strong nice having a new ignition switch, any of these troubleshooting steps don't work, I'm just going to cut a piece of rubber the same shape as the bottom of my kickstand, haha, but it would work

 

[Snuffy]

That will probably work but if it still drains then you might consider liquid electrical tape. You could dip the end of the kickstand in there a few times to make it thicker. Just a thought. Good luck

 

[LittleMike]

An excellent idea!

Keep your eyes open for more of these.

 

[Snuffy]

I want one or two for sure

Littlemike, take the battery (-) cable off the battery. Then press or tap the cable end to the battery's (-) post.

1. It may arc being the black box needs volts for the clock? Say it arcs either way.
2. Say no it does not arc. Then remove the wooden board or whatever you are using between the side-stand and floor.
3. Now say with the side-stand on the ground it arcs. Use a voltmeter between the cable and battery post and see how much volts are being drawn out.
4. Since it does show a draw, you can begin at the headlight bucket end and begin to pull each bullet or flat connector apart and note which wire stops the draw.

20/20 hindsight will say it was too simple as to understand WATT it was.

 

[Sven]

Say a volt reg? I could see the stator wires are 2, the 1 heavy wire out of the V/R going to the (+) battery would reverse out of the V/R? Just an off the wall guess. Unclip at the stator output first.

Hey look at that! I would be easy to carry the back pocket thanks bud! But I think I might have this whipped.

 

[LittleMike]

Hey fellas, my bike has sat on the concrete for 3 days now, and today it started right up I had 11.8 on the voltmeter. I would like to say I knew what exactly caused this problem so we can end this thread and try to help somebody else out. Here's what I've done! I put in a new ignition switch, I isolated the EHC from any metal and while I was there I did the same ignition module and I went through all the connectors I could find squirted WD and added the diametric grease. I should have probably gone one step at a time to find out exactly what the issue was but I'm always in a hurry to get the end result, sorry I did not take better notes on this.
Now I just need to get another Dixie horn and I'll be set, maybe I'll go with La Cucaracha this time.
