Hi all,
TL;DR
Setting Bosch SX motor to "lighting equipped" caused front light be very bright and burn out after a short while Guy at the shop claims he did it correctly but I have doubts. Voltage at the cable reads 13.6V not 12V. I'm trying to figure out if I've got a faulty light or more configuration is needed before I connect new one.
Full story
I've retrofitted back and front light set on Bosch SX bike. Lights are Cube Acid Pro-E 150 and Acid rear light that come on fully kitted variant of this bike. They are dedicated for Bosch BES3 with blue and red round connectors.
Cabling wise it was done by connecting a 3 way splitter BCH3361 to medium power port since SX does not have dedicated light ports. From there connectors were plug and play blue-blue (front light port), red-red (rear light port). Everything was verified for continuity and shorts with a multimeter.
Then I visited local shop that has Bosch diagnostic laptop. I was able to look what the guy is doing and he only toggled "lights equipped" to on and set light power to 16W.
After that lights turned on. After I while I've noticed that the front light is very hot, there's a smell of hot electronics (not burning but just hot new parts). Also Light mode button (3 step intensity) is not working. Did not think much about it at the time and proceeded to ride home.
30 minutes of light operation later Kiox shown "restart ebike", lights went off and bike has shut down. When I've turned it back on the same thing - brief flash of lights, error code with "restart ebike" on Kiox and a shutdown. Luckily I've figured out to pull front light plug which allowed my bike to stay on.
Back at the shop guy shown me light port over current error code. Each time we've tried to connect it back same story.
After a few tries front light stopped causing problems but now is completely dead, no initial flash followed by over current.
The question
What is more likely - a faulty light out of the box or misconfiguration when enabling lights? I could just connect a spare to test but at 100 EUR those guys are not cheap.
After another verification with multimeter cabling is fine but I've noticed that the voltage is not 12V as light manuals are saying but 13.6V. Is that something the guy at the shop forgot to set or normal?
