Can someone tell me how to disable the 12 volt power on my car? It is roadster #107, I understand it has no 12 volt battery? And by the way how does that work?

It does have a 12V battery so don't think you can disable it. Are you getting error message?
No error message, I'm installing a different stereo. I thought I'd heard that the early cars, did not have a 12 volt battery? Obviously they have a 12 volt system but I don't know how do it? Or maybe I was dreaming? :biggrin:
I'm almost done with the installation and haven't blown a fuse yet!
Thanks,

I remember reading the 1.5's don't have a 12v battery. Something about one of the sheets in the main battery is dedicated to car electronics.

If you have one, it would be located in front of the passenger side front tire behind a splash panel. It's a standard size motorcycle battery.
Early Roadsters (1.5s) don't have a 12V battery. 12V power comes straight from the main ESS.
To disable 12V power for radio work, the fuse box is your best bet. Take care with amplifiers, though. The available 12V power is very limited. The professionals installers who have done big upgrades have put in a separate battery to power their amplifiers.
e.g.; Worlds most bespoke Tesla Roadster | West Hollywood and the other one Al & Eds did for Dr Taras.

Thanks guys! The stereo is installed. I pulled three fuses, one apparently had something to do with the alarm because when I opened the door to get out of the car, the alarm went off! It then required my security code which I didn't know. I had the code in the house so all is well. Learn something new every day.:biggrin:
