I wonder if anyone has any idea what could be causing this to shut down. When you turn it on you hear the relay click and it all lights up. Then about 4-5 seconds later the relay clicks again and it turns off. I have looked carefully at it and checked all connections and it all seems ok.
Anyone have a suggestion?...

Re: Motorcycle flasher mystery.
Just to let everyone know I used led bulbs instead and it cured the misfire when the indicators were used.
I also found slightly tarnished contacts on all the fuses and found there was a diode in the fuse box which after I cleaned its contacts also cured a slight single occasional misfire when at low revs and under load like when slowly powering out of a slow turn (very annoying sometimes). -
Re: Motorcycle flasher mystery.
If I put .0.2uf caps between earth and each of the extra bulbs, would that work too?
The side stand and clutch/ neutral switch are safety features. In 1979 I had a serious life changing crash when I left the side stand down after filling with petrol after work. Then rose off to 1st left corner and unable to bank bike to go round corner and hit car coming other way. Lucky to be alive and a year in hospital. So glad of these features now....Leave a comment:

Re: Motorcycle flasher mystery.
Very interesting that. Just had the very problem of viewing angle with first set of bulbs that turned up.
They made indicators flash a bit faster and the indicaotor bulbs in these light units fit on the side so from the rear you are seeing the light coming from the side of the bulb and these led bulbs dont emit any light much from side on.Leave a comment:

Re: Motorcycle flasher mystery.
Just connected up a couple of old after market led motorcycle indicators in place of the normal 12v 21w incandescent bulbs and it works!
Just ordered a couple of clear Led reverse light bulbs off ebay so hopefully that should sort it.
Just out of interest if I has used a inline diode with a incadesessant bulb would that have worked too?

Re: Motorcycle flasher mystery.
Great idea STJ why didn't I think of that (light emitting DIODES). Hahaha.
Cheers will let you know if it works...Leave a comment:

Motorcycle flasher mystery.
usually get help on here for computers and monitors etc but I thought you guys are the best I can think off to help me solve a real mystery.
I have a Honda NT650V bike and recently fitted a towbar to tug a little trailer sometimes.
Everything was good until I connected up the trailer socket.
The problem is whenever I use the direction indicators/flashers it causes a misfire as soon as I cancel the flashers the misfire stops. The bike without the trailer lights attached is fine.
.So far Ive tried the following:
1) I replaced the battery for a higher A/h original... -
Re: Honda CX500 Motorcycle CDI ignition unit
Thanks Redwire that's great and yes my health has improved but not a lot of thanks to my GP doctors who were partially responsible for making me so unwell. By filling me with so many different pills every day that they were actually making my Tramadol pain killers less effective. Found this out after a really bad day when I threw up big time emptying all tablets that day from my stomach. Next day woke really better than in long time, So stopped all tablets just now except pain killers and every day getting better and better,...Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
ive tried all these things like amitriptyline, gabapentin, pregabalin and a few others. It is strange how Tramadol is so effective but its not just me as there are lots of evidence to back up its effectiveness. Its also got very few side effects especially compared to all the others and no one should try gabapentin as it made me put on 35 pounds weight and looked all bloated and puffed up.
All the weight eventually came back off once i stopped taking it.
just been told I cant get a operation to hopefully...Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
I too have difficult circumstances having multiple sclerosis as its my entire nervous system thats been damaged. A great deal of the pain is from my nerves making things feel like they are aching or stinging like my hands and feet are. Then there is the muscle spasms in legs and arms and pretty much any muscle anywhere can start going into spasm. Some times I even get my jaw getting huge cramp which hurts. They have tried everything on me drug and painkiller wise and things like morphine don't work because its nerve pain. Tramadols...Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
That's remarkable what you have done Redwire. think you are probable right about the enclosure when you need extra space for those better caps.
There is still another option that I can always relocate the CDI box elsewhere where there is more room if it wont fit in original location.
Here are some photos of the connectors and a list of what they are and where they go. Ive listed them in the same order as the schematic to make it easier.

Re: Honda CX500 Motorcycle CDI ignition unit
Yes STJ ive tried everything but this latest pain is literally a pain in the arse. Its spasms in my pelvic floor muscles that sting and burn and feels like a sharp knife cutting up inside your bum. Eye-watering! believe me. I am told there is no cure and I will just have to manage the pain with pain killers but they don't like giving me enough to keep it tolerable and I end up having to lay on bed (cant sit down). Mnd you if I got stoned I wouldn't care I suppose....Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
Hi everyone, I apologise for my silence recently but my multiple sclerosis has had be practically confined to a bed in agony. I am still hoping the docs find something pain killer wise that will allow me to resume my life swing as they say problem in incurable.
I am ever so grateful for terrific interest you put into helping me sort this CDI problem out.
Redwire if you are still interested in trying to design a alternative unit for it I would be eternally grateful. I will try and resume where I left off and continue checking...Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
I think the Bud PN-1321-DG is the most likely as its only a fraction higher than the original.
The original is still in great shape and there is a plastic sheet that keeps the pcb from shorting on the bottom. I would have to make a good job of sealing it up again but otherwise it would be ok and I could also reuse the original rubber sealing piece around the input and output connections. Original case inside dimensions are (mm):
Length=92mm, width=55mm, 30mm.
Just do what you prefer Redwire I would be more...Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
Just took a look on my bike and the CDI box sits in a recessed space in the frame, below the seat. Your box would not fit as the space available is not much bigger than the original CDI box which was 134 x 65 x 35.
The maximum size of the recess in the frame you can see in the picture is: 130 x 65 x 35mm.
The maximum size in the tail space behind seat is 180 x 90 x 45mm...Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
Have you managed to get all you need Redwire? I've almost finished putting the old unit back together and just have a few broken resistors to replace. I am only reassembling it for reference purposes if needed.
Is there any more info you need from me Redwire....Last edited by roadrash; 07-13-2021, 01:35 PM.Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
Yes you are right Redwire, the CDI box is located under the seat and is not in a exposed area to the wet. its more likely to just get damp under there.
The height of the box is more important than any other dimension as if its too high it might be subject to the seat pressing down on it or even the seat may not fit anymore. Otherwise there is plenty of room around it. If it was larger than the original it would be fine as long as its not higher.
I've spent hours going through that awful schematic and and...Leave a comment:

Re: Honda CX500 Motorcycle CDI ignition unit
Thanks very much for all your doing for me. Just had a bad time last few days as I lost my mother due to a blood clot in her heart. I Will be back on in few days.Last edited by roadrash; 07-08-2021, 04:10 PM.Leave a comment:
