Amon 5-pole slim relay surge coil countermeasures

My CBX uses Amon's 4-pole relay and 5-pole relay for the added wiring part.
It will be referred to as a relay below.
Coil surge countermeasures are written as noise removal.
When choosing a relay, it may be better to choose one that is labeled as noise-reducing.
When purchasing a relay, it is safer to purchase a relay that is labeled as noise-reducing from the beginning.
The other day when I was browsing the internet, I found that the current flows backwards after the coil is turned off.
I did not know. The relay is used to turn on and off the position lamp.
I felt that something was wrong.
I looked it up on the web.
It seems that it is necessary to apply surge coil countermeasures to the relay.
I'm not an expert on electricity, so I looked at the information my predecessors have posted on the web.
I also check to see if there is any similar information and try to install it on my own motorcycle.
The relay was melted, so I think it may be subject to a phenomenon called a surge coil.
I will write down the results of my own modifications to the relay.
I hope this article is helpful, but it's not accurate.
Please search the web beforehand before proceeding.

What is a surge coil?

Excerpt from wiki

サージ電流 - Wikipedia
In this relay case, when tuning the relay from on to off, It appears that a reverse voltage is being generated. It looks like the relay is melting or malfunctioning. It probably depends on how it is used and where it is used, but it seems better not to use relays in complicated places or use them without blowing a fuse. When dimming the LED light or processing it in conjunction with something else, it would be a good idea to be careful whether there are any devices that may be sensitive to voltage before or after the LED. In my opinion, I have a strong impression that things like air-fuel ratio meters break easily.

Take measures against surge coils

I purchased a rectifier diode 1000V5A from Amazon.

It's a procedure.
① Cut the film with scissors.
②Connect the black wire and blue wire with a rectifier diode. The direction in which the line is pointing is the cathode mark.
The cathode mark is on the blue line side.
③Solder to the board.
④ Cover it with a film and re-wrap it with insulating tape.

That's all. I've attached a photo, but it's not professional work so it's dirty.
When I use homemade surge coil countermeasures or noise removal, the polarity of the blue wire and black wire seems to become severe.
I have added titles to the photos, so please check them out in the next section.

The photo of the motorcycle shows the hazard button, the on/off position lamp, and the relays used to achieve this. From a waterproofing point of view, it may be better to fix it with adhesive.
This time, I simply wrapped insulating tape to make it easier to disassemble and check, and to prevent the rectifier diode from falling off.

Amon 5-pole slim relay surge coil countermeasures【summary】

I would have been happy if they had written a large warning in the manual, such as always using a fuse, not having coil surge countermeasures, and selling products with coil surge countermeasures separately.
It would be worse if you didn't know about it, so try to think that you're glad you didn't cause any big trouble.
It's DIY, including the work I do myself.
From now on, when purchasing relays, I will be careful to choose products that are labeled as noise-reducing.
I learned a lot this time, and the tuition wasn't too expensive, so it was a good thing.
Please be careful when touching electrical items.
See you again!
