Before you go ripping out alarms check your battery, eg a voltage check, you should have at least 12.2v anything less is a run down or cell damaged battery. The fact the main lights aren't coming on is pointing towards this, often older on the way out batteries will show little signs of dying, even when connected to a charger. As some die they just don't hold their charge once disconnected and die within hours or minutes, the alarm is possibly just doing it's job, e.g. it thinks the battery is being attacked and resets/arms.
I've seen this a lot over the years and it's nothing more than a battery going south. All that said it could be the alarm or a hopefully just a poor connection/earth, but check the battery first.
