Well, the LED optic chips are available and I have a few left but you don't need those.
Your problem was my problem. A friend accidentally shorted my cluster with the ignition on back in Sturgis. This is long after I shorted the LED optic chips on accident. We were troubleshooting my trailer turn signals. There's the rub. With the ignition on that chip is hot it's not dormant and open. It's closed and it burns out.
That particular switch mode power supply chip is not available. Unique to the cluster and I could not source a Japanese vendor that sold it directly. I checked on countless boards across the country, and that particular chip was custom-made for the gauge cluster by the manufacturer out of a Electronics house somewhere in Japan. I think it had a lambda stamp on it or something, but it was not in circulation. New cluster $1499. Second option, source a good used, cluster off ebay and harvest the chip off of that cluster for your own.
My electronics genius in San Diego also took my memory chip off my original cluster and transferred it to a new cluster So I could preserve original mileage data, with that chip intact and all of the custom poop he did to my gauge cluster so that I could never ever have this happen again he installed. Mostly diodes to keep back surges away so my alarm system works great.
If your guy had cycled the alarm with the ignition off, he would've just burnt the LED optic chips alone which is 12 V that will do the damage. Most bike alarms come with 12 V flasher wires that simply activate old or higher voltage turn signal circuits with no trouble at all. This particular cluster is ferociously sensitive. You place certain elements in the wiring to protect the cluster and you're good.
If you need my guys phone number, I'll give you Manny's number and he'll explain it to you better than I can but he's pretty much made my cluster bulletproof. My alarm works great, all my signals, including the trailer circuit work great, and I have no issues with the switch backs in the LEDs in the brake circuit turn signal circuit or front turn signal circuit. Everything works fine.
Bottom line, and this is just my opinion, Suzuki knew we would put alarms on our bikes, because they know a lot of us run alarms along with wheel locks and others theft protection-prevention. They should've isolated a unique wire to reduce the voltage to the turn signal circuit, so that the alarm could be installed hassle free not all of this other stuff we've had trouble with and had to go through to fix. Nothing in the owners manual, no advisories of any sort. Canbus according to Greg at Boost by Smith is a very temperamental animal.
