Hi there New to this forum and to the alphard so hello! We bought our Alphard camper conversion a few months ago from friends of ours who used it as their daily driver. Now it mostly sits and gets driven a couple of times a month at most. My partner went to start the camper tonight and set the alarm off as she used the wrong fob to deactivate the alarm (we have the optional toyota fitted version with the triangular sensor/LED thing on the dashboard). Now we can't deactivate it as the battery is flat. The van is sat making a loud ticking noise....which I assume is the alarm trying to sound but as the battery is flat it can't. When I tried to turn the ignition hoping to cancel it, there was very feint flashing of the dash lights and the interior mood(?) lights and the tick stopped but as the engine couldn't turn over it returned as soon as the key was removed. If I leave it like this any idea if it's damaging anything (apart from my nerves) and will it just go on until the battery is toatly dead? Please help with how can I fix this? Preferably without annoying the whole street. Should I remove the barrty and charge it? Where is it? Is it the one between the front seats or is that the leasure battery? This is the second time the battery has flattened so I'm thinking that there might be a drain somewhere and/or I need to get a new battery though this one is less than a year old. I'm usually pretty good with cars but this is our first hybrid and camper conversion and there's a fair bit to get my head round. Thanks!
