This community is such a wealth of knowledge…
Don’t forget the diode on the pulse line to protect the xAC.
Good im glad we could help.
Just to reiterate what amal is saying:
You will end up with 2 diodes;
the one shown in my image (courtesy of 12volt) is a flyback diode to stop damage to the relay and suppress emi created when the relay tuns off.
you will need to put one on the white wire feeding into the first relay.
Sounds like diodes are like fuses… no way that you can have too many.
Yes, I mean no, well kinda
The 2 diodes in this case provide 2 different forms of protection.
When you’re working with 12V systems, you can put diodes in all day. You get a diode, and you get a diode!
Not so much with 3.3V systems
Yeah .6fvd is significantly more of a percentage of 3.3v, one of the boards for work (a custom camera and laser driver solution) runs on 1.8v diodes start to be a bit problematic
Putting this all together for ya @Steven1727.
You need to know 2 things to understand what’s being referenced.
First you actually lose about .7 volts when you pass through a diode. (The right way, the wrong way don’t work at all.)
Second, Engineers and Technicians will haggle back and forth over a half a volt in the same way and with the same passion that Historians and Military Officers will deconstruct, study, reconstruct and re-fight the Civil War. Seriously it gets intense.
Your motorcycle probably has;
9-10 volts while starting.
10.5 volts when battery dead and no load or charging
12.5 volts when fully charged with no load or charging.
13.5-14 volts while running and charging.
Don’t sweat that .7v
I’m typically really good when it comes to car wiring… But these diodes are throwing a bone in the bucket I have never had to deal with lol. Thanks y’all. I’m even thinking about adding some LED diodes to show that The chip has been accepted and the system is armed.
The coiled up wire with LED on your reader will come on while a chip is being read.
You can also remove that wire if you’re careful.
I wish it was only Satur9 bending my brain when I read through here.
Very interested in how this turns out. I’d very much like my new bike to start keyless.
hi guys ive had one of these in my bike for about a month now and it works great, no complaints at all its been very reliable, i have now just added a voice output to it and i thought i would share it with you!
i live on the facebook group. and im rarely on here.
Nice work and thanks for the share.
Would be cool if you did your own separate project for this one, otherwise it may get over looked.
