I have a Meta 357T Cat 1 alram on my 748. I had to disconnect the rear indicators and I think one of the leads must have touched the frame. Problem I have is that where as before the indicators used to flash once or twice when activating / deactivating they don't do that anymore and the only hint I get is when I turn the ignition key it beeps when the alram is on. My main concern is that I immobilised the bike and about 30 seconds later with the bike on its stand not being touched, the alram went off. As the bike is in my Mums garage and I don't live there I am not sure what I should do.
I have a customers bike in that appears to act the same. It had gone over on one of the indicators. There's some srt of error indication via the LED I think. It's been tested at a Meta dealer and the PCB is shot.
